Notice of Pre-AIA or AIA Status
The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
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:
A person shall be entitled to a patent unless –
(a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention.
Claim(s) 1-8, 10-19 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Takahashi et al. DE 102021100122 A1.
Independent Claim 1: Takahashi discloses a robot used by a method for operating an autonomous mobile green area maintenance robot (10) having a maintenance tool (20), wherein a maintenance height of the maintenance tool is adjustable (via 38), the method comprising the steps of:
a) monitoring whether a criterion for being stuck is satisfied (via 44a1), wherein the criterion for being stuck is characteristic of the green area maintenance robot being stuck (see the boxed text on page 2 and the circled text of page 5 of the attached document);
b) increasing the maintenance height when the criterion for being stuck is satisfied (at S116, see the boxed text of pages 5 and 11 of the attached document); and
after step b), reducing the maintenance height and starting movement of the maintenance tool (at S120) when a reversion criterion is satisfied,
wherein the reversion criterion is that the criterion for being stuck is no longer satisfied for a minimum period of time (when the strength of the area signal and acceleration signal are affirmed then normal routine is initiated again, see S104), and
wherein the maintenance height is reduced to a value such as that before the criterion for being stuck was satisfied (S120), as per claim 1.
Dependent Claims 2-8, 10-17: Takahashi further discloses wherein the green area maintenance robot (10) has a locomotion mechanism (16, 16, 26L, 26R) designed for locomotion of the green area maintenance robot,
wherein a contact part (40) of the green area maintenance robot is designed to perform a monitoring movement caused by the locomotion and the condition of being stuck,
wherein the contact part is mounted movably in relation to the locomotion mechanism, and
wherein the criterion for being stuck is that the monitoring movement is caused (see the circled text of page 5 of the attached document), as per claim 2;
wherein the green area maintenance robot (10) has a locomotion drive system (16, 16, 26L, 26R) designed for locomotion of the green area maintenance robot, and
wherein the criterion for being stuck is that, in spite of operation of the locomotion drive system, the green area maintenance robot is not moving as in the case when it is not stuck (via drive wheel rotation sensor 56 in addition to the acceleration sensor 50 or impeller rotation sensor 58, as described in the boxed text of page 12 of the attached document), as per claim 3;
wherein the monitoring comprises:
sensing locomotion by way of determining a change in distance, position and/or route of the green area maintenance robot (via GPS sensor 54, see the boxed text of page 12 of the attached document) and/or by way of magnetic field measurement (via magnetic sensors 36, see the boxed text on page 7 of the attached document), as per claim 4;
wherein the monitoring comprises global and/or local position determination (GPS sensor 54), as per claim 5;
wherein the maintenance tool (20) is rotationally movable (via motor 22), and
wherein step b) comprises stopping the movement of the maintenance tool when the criterion for being stuck is satisfied (see the circled text of page 11 of the attached document), as per claim 6;
wherein the green area maintenance robot (10) has a tool movement drive system (22),
wherein the tool movement drive system is designed for moving the maintenance tool (20), and
wherein step b) comprises stopping operation of the tool movement drive system when the criterion for being stuck is satisfied (see the circled text of page 11 of the attached document), as per claim 7;
wherein the green area maintenance robot (10) has a locomotion drive system (16, 16, 26L, 26R),
wherein the locomotion drive system is designed for locomotion of the green area maintenance robot, and
wherein step b) comprises operating the locomotion drive system to move the green area maintenance robot in an averted locomotion direction (as described in the boxed text of page 8 of the attached document) after the maintenance height has been increased, and after the movement of the maintenance tool has been stopped (see S126, Fig. 10), as per claim 8;
wherein the green area maintenance robot (10) has a protection device (12) designed to protect against access into the maintenance tool,
wherein the protection device has the contact part (12b), and/or
wherein a protection height of the protection device is adjustable, and wherein step b) comprises increasing the protection height when the criterion for being stuck is satisfied, and wherein the method comprises the step of reducing the protection height after step b), as per claim 10;
wherein the maintenance height (of maintenance tool 20) and/or the protection height are/is adjustable in a range of from 0 cm to 20 cm (the height of the robot is about 30cm which means the maintenance height is movable in a range from 0-20cm via adjustment device 38 as seen in Fig. 1), as per claim 11;
wherein the green area maintenance robot (10) is designed such that the adjustment of the maintenance height (via motor 38a) and/or the protection height are/is independent of locomotion (via motors 26L, 26R) of the green area maintenance robot, as per claim 12;
wherein the green area maintenance robot (10) has a locomotion drive system (16, 16, 26L, 26R) designed for locomotion of the green area maintenance robot,
wherein the green area maintenance robot has a height adjustment drive system (38a) designed to adjust the maintenance height (of maintenance tool 20) and/or the protection height, and
wherein the height adjustment drive system (38a) is independent of the locomotion drive system (26L, 26R), as per claim 13;
wherein the contact part (40) and/or the protection device (12b) are/is arranged in front of the maintenance tool (as seen in Fig. 1, contact part 40 is in front of maintenance tool 20 and protection device 12b extends from the front of the robot to the back and so is also arranged in front of the maintenance tool 20), as per claim 14;
wherein the green area maintenance robot (10) has a locomotion frame (12a) and/or a covering hood (also 12b),
wherein the locomotion frame and/or the covering hood (12b) are/is arranged above the contact part (40) and/or the maintenance tool (20) and/or the protection device, and
wherein the maintenance height and/or the protection height are/is adjustable in relation to the locomotion frame and/or the covering hood, and/or

a height adjustment device (38), wherein the height adjustment device is designed to increase the maintenance height when the criterion for being stuck is satisfied (see S126 in Fig. 10); and
and a tool movement drive system (26),
wherein when a reversion criterion is satisfied (affirmation that the area signal and acceleration signals are changing), the height adjustment device is designed to reduce the maintenance height (at S120) and the tool movement drive system is designed to start movement of the maintenance tool (at S104),

Response to Arguments
Please see the updated art rejection in response to applicant’s claim amendments. Takahashi does indeed disclose the reversion of the blade height back to the original setting and return to normal the normal work process (at S120 and S104) once the controller has determined that the robotic mower has become unstuck by comparing area and acceleration signals.
See also newly cited Kruckeberg 9,861,035 and Conrad US 20200120866 A1 which both disclose similar reversion steps to those newly recited in amended claims 1 and 18.
