This displacement detecting sensor is provided with two encoders attached to a first link and a second link that are coupled in such a way as to be capable of moving relative to a certain axis, wherein: the two encoders are provided with two scale members at different distances from the axis, and two detectors for detecting scales on the respective two scale members; a positional relationship between the scale members and the detectors changes in accordance with an external force accepted at the distal end of the second link, generating a difference between the two scales detected by the two encoders; and the displacement of the distal end of the second link can be detected on the basis of the two scales.

Displacement detecting sensor, control device, and control system

A robot joint structure includes a motor configured to be used for a robot joint shaft capable of turning about a vertical axis, a motor-side gear mounted on a shaft of the motor, an auxiliary bearing configured to axially support the shaft supplementally, an adapter configured to integrate the motor, the motor-side gear, and the auxiliary bearing, and a moving mechanism configured to move a unit structure integrated by the adaptor in a radial direction of the motor such that the motor-side gear approaches a mating gear meshing with the motor-side gear.

Involute interpolation method

A method and apparatus for controlling the feed speed of a machine in a numerical control system having a manual pulse generator for generating pulses in response to a manual operation. The numerical control system numerically controls the machine by supplying the machine with the generated pulses as feed pulses in a manual feed mode and with feed pulses corresponding to a commanded feed speed in modes other than the manual feed mode. The commanded feed speed is modified in accordance with an override quantity stored in a register. The method includes selectively designating the modes other than the manual feed mode, changing the override quantity, which is stored in the register, based on the pulses generated by the manual pulse generator and in accordance with the designated mode, and modifying the commanded feed speed in accordance with the override quantity stored in the register.
