Abstract
The end effector 10 includes a joint section 11 connected to a robotic arm 220, a working section 14 for performing work on an object 500, an actuator 40 is located between the joint section 11 and the working section 14 and moves the working section 14 in a first direction in which the joint section 11 and the working section 14 are aligned, a piezoelectric element 45 that drives an actuator 40.
Claims8
An end effector, comprising:
- a joint section that is connected to a robotic arm;
- a working section that performs work on an object;
- an actuator that is located between the joint section and the working section and that moves the working section in a first direction in which the joint section and the working section are aligned;
- and
- a piezoelectric element that drives the actuator.
2 more elements
A control method of an end effector including
- a joint section that is connected to a robotic arm, a working section that performs work on an object, an actuator that is located between the joint section and the working section and that moves the working section in a first direction in which the joint section and the working section are aligned, and a piezoelectric element that drives the actuator,
- the control method comprising:
- controlling drive voltage of the piezoelectric element so that pressing force of the actuator becomes constant.
