Abstract
A position control method for controlling a position of a movable portion, includes: performing control of allowing the movable portion to approach a predetermined position by moving the movable portion; and performing control of moving the movable portion to the predetermined position by moving the movable portion and detecting a relative position of the movable portion with respect to the predetermined position by using an imaging unit.
Claims11
A position control method for controlling a position of a movable portion according to instructions from a processor, the position control method comprising:
- moving the movable portion to a predetermined position by moving the movable portion and detecting a relative position of the movable portion with respect to the predetermined position by an imaging unit according to a first instruction from the processor;
- and
- suppressing a first vibration of the movable portion based on movement of the movable portion according to a second instruction from the processor, the movement being detected by an inertial sensor,
- wherein a vibration suppressing period during which the first vibration of the movable portion is suppressed overlaps at least a part of a movement period during which the movable portion moves to the predetermined position.
1 more element
A robot comprising:
- a movable portion;
- an imaging unit that detects a relative position of the movable portion with respect to a predetermined position;
- a movement control unit that moves the movable portion to the predetermined position by using information on an image captured by the imaging unit;
- an inertial sensor that detects movement of the movable portion;
- and
- a vibration suppressing control unit that suppresses a first vibration of the movable portion based on the detected movement of the movable portion, the vibration suppressing control unit that is adopted to overlap a vibration suppressing period during which the first vibration of the movable portion is suppressed with a movement period during which the movable portion moves to the predetermined portion.
