The information disclosure statement (IDS) submitted on 01/02/2025 is in compliance with the provisions of 37 CFR 1.97. Accordingly, the information disclosure statement is being considered by the examiner.
Claim Rejections - 35 USC § 112
The following is a quotation of 35 U.S.C. 112(b):
(b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention.
The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph:
The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention.
Claims 12-14 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention.
Claims 12-14 recite the limitation “a gross slip detection frame rate counter.”
It is unclear what “gross slip” is referring to. The specification does not appear to provide a definition for the meaning of the limitation. Therefore, the metes and bounds of the limitation cannot be ascertained.
Claim Rejections - 35 USC § 102
The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:

Claim Rejections - 35 USC § 103
The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action:
A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
Claims 2-4 and 16 are rejected under 35 U.S.C. 103 as being unpatentable over Rodriguez Garcia et al. (US 2021/0146532 A1), in view of Tsuboi et al. (US 2009/0076657 A1).
Regarding claim 2, Rodriguez Garcia does not specifically teach wherein the sensor unit includes an elastically deformable sensor sheet having a plurality of capacitive elements that detects a pressure applied to the gripping surface, and the control apparatus detects the slip of the work on the gripping surface based on a change in pressure detected by the plurality of capacitive elements.
However, in the same field of endeavor, Tsuboi teaches:
wherein the sensor unit includes an elastically deformable sensor sheet ([0079] “The deforming section 41 is made of a viscoelastic body having a viscoelastic characteristic such as a silicon gel material. The deforming section 41 can be easily deformed by a load from the outside.”) having a plurality of capacitive elements that detects a pressure applied to the gripping surface ([0067] “ Each of the sensors 21 provided in the robot hand 1 includes a capacitance-type pressure sensor that detects only normal force (a normal direction component of reaction of gripping force) perpendicular to a surface of the sensor.”; [0079] “The pressure detecting section 42 includes a capacitance-type pressure sensor that detects pressure making use of a principle of detection of, for example, a resistance change and a capacitance change.”), and
the control apparatus detects the slip of the work on the gripping surface based on a change in pressure detected by the plurality of capacitive elements ([0067] “The sensor 21 detects, on the basis of the detected distributed pressure value, a slip between a gripped object and a fingertip”; [0080] “The pressure detecting section 42 can acquire amounts equivalent to a slip direction and slip speed according to a slip by using the pressure center for sensing of a slip.”).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the teachings of Rodriguez Garcia to include an elastically deformable sensor sheet having a plurality of capacitive elements that detects a pressure applied to the gripping surface, and detect the slip of the work on the gripping surface based on a change in pressure detected by the plurality of capacitive elements, as taught by Tsuboi, in order to accurately detect a slippage of the work.
Regarding claim 3, Rodriguez Garcia does not specifically teach wherein the control apparatus detects the slip of the work on the gripping surface responsive to a number of capacitive elements that have a pressure detection value changing, within a predetermined time, meeting a predetermined threshold.
However, Tsuboi teaches:
wherein the control apparatus detects the slip of the work on the gripping surface responsive to a number of capacitive elements (Fig. 5; [0089] “one-hundred sixty-eight sensor elements 52”) that have a pressure detection value changing ([0094] “The sensor elements 52 output a distributed pressure value detected by using a capacitance change as a detection principle to the signal processing unit 53. The principle of detection of the distributed pressure value may be other than the capacitance change.”; [0103] “the pressure-center calculating unit 122 calculates a pressure center position using distributed pressure values of the sensor elements 52 for which the contact detection is performed by the contact detecting unit 121.”), within a predetermined time ([0104] “ The pressure-center-movement calculating unit 123 as pressure-center-movement calculating means for calculating a movement value of a pressure center position using a temporal change of the pressure center position accumulates pressure center positions from the pressure-center calculating unit 122 in time series. The pressure-center-movement calculating unit 123 calculates, for example, a difference in a moving average of the accumulated pressure center positions or a difference among the pressure center positions and outputs the calculated difference to the slip detecting unit 124 as a pressure center movement calculated value.”), meeting a predetermined threshold ([0105] “The slip detecting unit 124 as slip-detection-value calculating means for calculating a slip detection value on the basis of the movement value of the pressure center position performs a pressure center movement detection calculation using a calculation result from the pressure-center-movement calculating unit 123. The slip detecting unit 124 compares a calculation result of the pressure center movement detection calculation with a predetermined threshold (hereinafter referred to as judgment threshold) and detects a slip”).
It would have been obvious to one of ordinary skill to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the teachings of Rodriguez Garcia, in view of Tsuboi, to detect the slip of the work on the gripping surface responsive to a number of capacitive elements having a pressure detection value changing, within a predetermined time, meeting a predetermined threshold, as taught by Tsuboi. Such modification can accurately detect a slip at the time when an object slips very slowly.
Regarding claim 4, Rodriguez Garcia does not specifically teach wherein the control apparatus detects the slip of the work on the gripping surface responsive to a pressure center position or a pressure distribution calculated based on pressure detection values of the plurality of capacitive elements changes within a predetermined time.
However, Tsuboi teaches:
wherein the control apparatus detects the slip of the work on the gripping surface ([0094] “The sensor elements 52 output a distributed pressure value detected by using a capacitance change as a detection principle to the signal processing unit 53. The principle of detection of the distributed pressure value may be other than the capacitance change.”; [0103] “the pressure-center calculating unit 122 calculates a pressure center position using distributed pressure values of the sensor elements 52 for which the contact detection is performed by the contact detecting unit 121.”) responsive to a pressure center position or a pressure distribution calculated based on pressure detection values of the plurality of capacitive elements changes within a predetermined time ([0104] “ The pressure-center-movement calculating unit 123 as pressure-center-movement calculating means for calculating a movement value of a pressure center position using a temporal change of the pressure center position accumulates pressure center positions from the pressure-center calculating unit 122 in time series. The pressure-center-movement calculating unit 123 calculates, for example, a difference in a moving average of the accumulated pressure center positions or a difference among the pressure center positions and outputs the calculated difference to the slip detecting unit 124 as a pressure center movement calculated value.”).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the teachings of Rodriguez Garcia, in view of Tsuboi, to detect the slip of the work on the gripping surface responsive to a pressure center position or a pressure distribution calculated based on pressure detection values of the plurality of capacitive elements changes within a predetermined time, as taught by Tsuboi. Such modification allows the robot to detect a slip at the time when an object slips very slowly.
Regarding claim 16, Rodriguez Garcia does not specifically teach determining whether a predetermined pressure distribution profile is present.
However, Tsuboi teaches:
determining whether a predetermined pressure distribution profile is present ([0104] “The pressure-center-movement calculating unit 123 calculates, for example, a difference in a moving average of the accumulated pressure center positions or a difference among the pressure center positions and outputs the calculated difference to the slip detecting unit 124 as a pressure center movement calculated value.”; [0105] “The slip detecting unit 124 compares a calculation result of the pressure center movement detection calculation with a predetermined threshold (hereinafter referred to as judgment threshold) and detects a slip.”).
It would have been obvious to one of ordinary skill to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the teachings of Rodriguez Garcia, in view of Tsuboi, to determine whether a predetermined pressure distribution profile is present, as taught by Tsuboi, in order to detect whether a slip of the work has occurred.
Claim 5 is rejected under 35 U.S.C. 103 as being unpatentable over Rodriguez Garcia et al. (US 2021/0146532 A1), in view of Suzuki (US 9,868,215).
Regarding claim 5, Rodriguez Garcia further teaches wherein the control apparatus causes, from a state of gripping the work with a first gripping force, a pressure adjustment adjusting the work ([0050] “Of course, each end effector may be commanded to adjust only the magnitude of its applied force, only the direction of its applied force, or both the magnitude and the direction of its applied force.”) and a movement changing the relative position of the hand portion with respect to the work ([0050] “ while the second end effector 120b may be commanded to rotate to adjust the direction of the force it applies to the object 150 (indicated by the curved arrow in FIG. 4B)”).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the teachings of Rodriguez Garcia to cause, from a state of gripping the work with a first gripping force, a pressure adjustment adjusting the work and a movement changing the relative position of the hand portion with respect to the work, as taught by Rodriguez Garcia, in order to prevent or limit the slippage of the work.
Rodriguez Garcia does not specifically teach the pressure adjustment includes adjusting the work from the first gripping force to a second gripping force lower than the first gripping force.
However, in the same field of endeavor, Suzuki teaches the pressure adjustment includes adjusting the work from the first gripping force to a second gripping force lower than the first gripping force (Claim 1 “the robot hand controller controls the robot hand so as to decrease a force, by which the robot hand grips the object, after the robot hand is arranged at the position and posture in which the moment is generated at the object, to allow the object to rotate relative to the robot hand by the action of gravity while preventing the object from dropping from the robot hand”).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the teachings of Rodriguez Garcia to adjust the work from the first gripping force to a second gripping force lower than the first gripping force, as taught by Suzuki, in order to allow the work to rotate relative to the robot hand by the action of gravity while preventing the work from dropping from the robot hand, as stated by Suzuki.
Claim 6 is rejected under 35 U.S.C. 103 as being unpatentable over Rodriguez Garcia et al. (US 2021/0146532 A1), in view of Suzuki (US 9,868,215), and further in view of Otsuru (US 2020/0198899 A1).
Regarding claim 6, neither Garcia nor Suzuki specifically teaches wherein the control apparatus causes a change from a first attitude in which a distal end of the hand portion is oriented downward in a gravity direction to a second attitude in which the distal end of the hand portion is oriented in a direction orthogonal to the gravity direction.
However, Otsuru teaches:
wherein the control apparatus causes a change from a first attitude in which a distal end of the hand portion is oriented downward in a gravity direction to a second attitude in which the distal end of the hand portion is oriented in a direction orthogonal to the gravity direction ([0021] “the moving device including a turning-over section configured to rotate the suction hand around an axis in a horizontal direction perpendicular to a gravity direction, from an orientation in which the suction unit faces down along the gravity direction and a suction surface of the suction unit intersects the gravity direction”).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the teachings of Garcia, in view of Suzuki, to cause a change from a first attitude in which a distal end of the hand portion is oriented downward in a gravity direction to a second attitude in which the distal end of the hand portion is oriented in a direction orthogonal to the gravity direction, as taught by Otsuru, in order to efficiently transport the work.
Claim 7 is rejected under 35 U.S.C. 103 as being unpatentable over Rodriguez Garcia et al. (US 2021/0146532 A1), in view of Suzuki (US 9,868,215), and further in view of Sakai et al. (JP 2018126836 A).
Regarding claim 7, neither Rodriguez Garcia nor Suzuki specifically teach wherein the control apparatus causes a movement in a longitudinal direction of the work.
However, in the same field of endeavor, Sakai teaches:
wherein the control apparatus causes a movement in a longitudinal direction of the work ([0026] “Therefore, by gripping by the first hand portion 30, it moves in the lateral direction of the gripping target object 100 and is gripped by the second hand portion 40, whereby it moves in the longitudinal direction of the gripping object.”).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the teachings of Rodriguez Garcia, in view of Suzuki, to cause a movement in a longitudinal direction of the work, as taught by Sakai, in order to allow the robot to grip the object.
Claims 8-9 are rejected under 35 U.S.C. 103 as being unpatentable over Rodriguez Garcia et al. (US 2021/0146532 A1), in view of Tsuboi et al. (US 2009/0076657 A1), and further in view of Katsuhara et al. (US 2021/0208012 A1).
Regarding claim 8, Rodriguez Garcia does not specifically teach wherein the sensor sheet comprises a pressure sensor, the pressure sensor including a sensor electrode layer in which the plurality of capacitive elements are arranged in a matrix form, a reference electrode layer, and a deformation layer disposed between the sensor electrode layer and the reference electrode layer.
However, Tsuboi teaches:
wherein the sensor sheet comprises a pressure sensor (Fig. 3A; [0077] “sensor 21”), the pressure sensor including a sensor electrode layer in which the plurality of capacitive elements are arranged in a matrix form ([0088] “The pressure detecting section 42 includes, for example, plural pressure detection elements (hereinafter also referred to as sensor elements) 52 arranged in a matrix shape on a flexible substrate 51”), and a deformation layer (Fig. 3A; [0077] “a deforming section 41”).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the teachings of Rodriguez Garcia, in view of Tsuboi, to include a pressure sensor including a sensor electrode layer in which the plurality of capacitive elements are arranged in a matrix form, and a deformation layer, as taught by Tsuboi, in order to acquire pressure information of the object while improving safety for humans and realizing physical interaction with higher affinity with humans, as stated by Tsuboi in [0082].
Tsuboi does not specifically teach a reference electrode layer, and the deformation layer is disposed between the sensor electrode layer and the reference electrode layer.
However, Katsuhara teaches:
a pressure sensor ([0038] “sensor 10 has an elongated sheet shape, and is capable of detecting pressure applied to both main faces of the sensor 10”) including a sensor electrode layer (Fig. 2; [0046] “sensor electrode layer 20”), a reference electrode layer (Fig. 2; [0059] “ The electrode base 11 includes a flexible base 11c and a reference electrode layer (hereinafter referred to as “REF electrode layer”) 11d provided on one main face of the base 11c.”), and a deformation layer (Fig. 2; [0040] “deformable layer 12”) disposed between the sensor electrode layer and the reference electrode layer ([0040] “The deformable layer 12 is provided between the one main face of the electrode base 11 and the one main face of the sensor electrode layer 20”).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the teachings of Rodriguez Garcia, in view of Tsuboi, to include a reference electrode layer, and dispose the deformation layer between the sensor electrode layer and the reference electrode layer, as taught by Katsuhara. Such modified configuration of the pressure sensor enables an input operation with a higher degree of flexibility, as stated by Katsuhara in [0151].
Regarding claim 9, Rodriguez Garcia does not specifically teach wherein the sensor sheet includes a pair of pressure sensors, the pressure sensors each having a sensor electrode layer in which the plurality of capacitive elements are arranged in a matrix form, a reference electrode layer, and a de- formation layer disposed between the sensor electrode layer and the reference electrode layer, and a separation layer comprising a viscoelastic material disposed between the pair of pressure sensors.
However, Tsuboi teaches:
wherein the sensor sheet
includes a pair of pressure sensors (Fig. 1A shows a plurality of sensors 21”), the pressure sensors each having a sensor electrode layer in which the plurality of capacitive elements ([0067] “a capacitance-type pressure sensor”) are arranged in a matrix form ([0088] “The pressure detecting section 42 includes, for example, plural pressure detection elements (hereinafter also referred to as sensor elements) 52 arranged in a matrix shape on a flexible substrate 51”), a deformation layer (Fig. 3A; [0077] “a deforming section 41”), and
a separation layer comprising a viscoelastic material disposed between the pair of pressure sensors ([0067] “The sensor 21 has on the surface thereof a viscoelastic body having softness like the human skin. The viscoelastic body is deformed into various shapes by force received from the outside and a form of the force, whereby pressure is dispersed to the sensor 21 on the inside.” – Since the sensor 21 has a viscoelastic layer on the surface and Fig. 1B shows the sensors 21 are placed next to each other, the viscoelastic layer of each the sensor 21 separates the sensors 21 from each other).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the teachings of Rodriguez Garcia, in view of Tsuboi, to include a pair of pressure sensors, the pressure sensor each including a sensor electrode layer in which the plurality of capacitive elements are arranged in a matrix form, and a deformation layer, and a separation layer comprising a viscoelastic material disposed between the pair of pressure sensors, as taught by Tsuboi, in order to acquire pressure information of the object while improving safety for humans and realizing physical interaction with higher affinity with humans, as stated by Tsuboi in [0082].
Tsuboi does not specifically teach a reference electrode layer, and the deformation layer is disposed between the sensor electrode layer and the reference electrode layer.
However, Katsuhara teaches:
a pressure sensor ([0038] “sensor 10 has an elongated sheet shape, and is capable of detecting pressure applied to both main faces of the sensor 10”) including a sensor electrode layer (Fig. 2; [0046] “sensor electrode layer 20”), a reference electrode layer (Fig. 2; [0059] “ The electrode base 11 includes a flexible base 11c and a reference electrode layer (hereinafter referred to as “REF electrode layer”) 11d provided on one main face of the base 11c.”), and a deformation layer (Fig. 2; [0040] “deformable layer 12”) disposed between the sensor electrode layer and the reference electrode layer ([0040] “The deformable layer 12 is provided between the one main face of the electrode base 11 and the one main face of the sensor electrode layer 20”).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the teachings of Rodriguez Garcia, in view of Tsuboi, to include a reference electrode layer, and dispose the deformation layer between the sensor electrode layer and the reference electrode layer, as taught by Katsuhara. Such modified configuration of the pressure sensor enables an input operation with a higher degree of flexibility, as stated by Katsuhara in [0151].
Claims 12-14 are rejected under 35 U.S.C. 103 as being unpatentable over Rodriguez Garcia et al. (US 2021/0146532 A1), in view of Yamamoto et al. (JP2005177977 A).
Regarding claim 12, Rodriguez Garcia does not specifically teach incrementing a gross slip detection frame rate counter.
However, in the same field of endeavor, Yamamoto teaches:
incrementing a gross slip detection frame rate counter ([0026] “the control unit 4 determines the slip amount of the object X by counting the number of pulses of the sensor output (detection signal) of the slip sensor 1”).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the teachings of Rodriguez Garcia to increment a gross slip detection frame rate counter, as taught by Yamamoto, in order to determine a slip of amount of the work.
Regarding claim 13, Rodriguez Garcia does not specifically teach determining whether the gross slip detection frame rate counter meets a threshold.
However, Yamamoto teaches determining whether the gross slip detection frame rate counter meets a threshold ([0025] “ a detection signal with the number of pulses corresponding to the amount of change (movement amount) is output, and the object to the slip sensor 1 is output. If X is stationary, the number of pulses is zero, that is, no detection signal is output.”; [0026] “the control unit 4 determines the slip amount of the object X by counting the number of pulses of the sensor output (detection signal) of the slip sensor 1, and refers to the sensor outputs of the angle sensor 2 and the torque sensor 3, By controlling the driving unit 54 so that the slip amount becomes zero ...”) – The threshold can be 0; hence, if the slip amount of the object is detected, the gross slip detection frame rate/number of pulses of sensor output is more than zero and therefore has met the threshold.).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the teachings of Rodriguez Garcia to determine whether the gross slip detection frame rate counter meets a threshold, as taught by Yamamoto, in order to determine a slip of amount of the work.
Regarding claim 14, Rodriguez Garcia does not specifically responsive to determining the gross slip detection frame rate counter meets the threshold, reset the gross slip detection frame rate counter to zero.
However, Yamamoto teaches:
responsive to determining the gross slip detection frame rate counter meets the threshold, reset the gross slip detection frame rate counter to zero ([0026] “the control unit 4 determines the slip amount of the object X by counting the number of pulses of the sensor output (detection signal) of the slip sensor 1, and refers to the sensor outputs of the angle sensor 2 and the torque sensor 3, By controlling the driving unit 54 so that the slip amount becomes zero and adjusting the gripping force of the robot hand 50, the object X gripped by the robot hand 50 is prevented from slipping down.”).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the teachings of Rodriguez Garcia to reset the gross slip detection frame rate counter to zero responsive to determining the gross slip detection frame rate counter meets the threshold, as taught by Yamamoto, in order to adjust a gripping force of the robot hand and prevent the work from slipping down.
