Numerals 300(plug in/out apparatus), 313(holding mechanism), "server rack column"(accommodating frame) Allowable Subject Matter Claims 16-18 are allowed. The following is an examiner’s statement of reasons for allowance: Independent Claim 16 recites limitations that include the following: A device assembly method, comprising: receiving, by a control apparatus, an operation and maintenance instruction, wherein the operation and maintenance instruction comprises an operation type, a rack number, a slot number, and a code of a to-be-plugged device; controlling, by the control apparatus based on the operation and maintenance instruction, a mobile apparatus to move to a first location, wherein the first location identifies a rack in which the device is assembled; controlling, by the control apparatus, a first visual mechanism to scan, to obtain a current rack number, and verify whether the current rack number is consistent with the rack number in the operation and maintenance instruction; controlling, by the control apparatus, the lifting apparatus to drive a plug in/out apparatus to move to a target location in a first direction after verifying that the current rack number is consistent with the rack number in the operation and maintenance instruction, wherein the target location is a slot for storing the device in the rack, and the first direction is perpendicular to the ground; controlling, by the control apparatus, the first visual mechanism to scan, to obtain a current slot number and a code of a current to-be-plugged device, and verify whether the current slot number and the code of the current to-be-plugged device are consistent with the slot number and the code of the to-be-plugged device in the operation and maintenance instruction; after verifying that the current slot number and the code of the current to-be-plugged device are consistent with the slot number and the code of the to-be-plugged device in the operation and maintenance instruction, obtaining, by the control apparatus, pose information of a current slot and current pose information of a plug in/out mechanism, and controlling, based on the pose information of the current slot and the current pose information of the plug in/out mechanism, a pose adjustment mechanism of the plug in/out apparatus to adjust a pose of the plug in/out mechanism, to enable a hook arm of the plug in/out mechanism to be aligned with the slot; and controlling, by the control apparatus, the hook arm to extend, to plug the to-be-plugged device into the slot, or unplug the to-be-plugged device out of the slot. These limitations, alone and in combination with the other limitations in the independent and dependent claims, were neither found, nor taught or fairly suggested, in the prior art of record. Claims 2-4, 6, and 8-15 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims. In the alternative, one or more of these claims may be incorporated as further limitations into the respective rejected independent base claim from which they depend. These allowable claims would make the rejected independent base claim allowable because the rejected base claim would then contain subject matter that was neither disclosed nor taught or fairly suggested in the prior art of record. Conclusion The prior art made of record and not relied upon is considered pertinent to Applicant's disclosure because the prior art references contain subject matter that relates to one or more of Applicant’s claim limitations. Any hypothetical prior art rejection based on these references would require impermissible hindsight reasoning.
