Force sensor protection mechanism, end effector, and robot arm

摘要

An end effector base and a finger unit are formed as separate members, and are disposed with a space therebetween. A force sensor is fixed to a finger base of the finger unit, and is disposed with a space between it and the end effector base. Three supporting members are supported by the end effector base, and are configured to be able to be moved by the driving of a driving unit to a position where they support the force sensor and a position where they are separated from the force sensor and support the finger unit.
