Abstract:
1. An under-actuated robotic finger with joint locking mechanisms, comprising: a base body; a first finger part coupled rotatably to the base body; a second finger part coupled rotatably to the first finger part; a first hinge part adapted to rotatably connect the base body and the first finger part; a second hinge part adapted to rotatably connect the first finger part and the second finger part; a first locking mechanism having a first toothed part, a first locker adapted to be engaged with the first toothed part to restrict the rotation of the first finger part, and a first locker-operating part adapted to operate the first locker; and a second locking mechanism having a second toothed part, a second locker adapted to be engaged with the second toothed part to restrict the rotation of the second finger part, and a second locker-operating part adapted to operate the second locker, wherein each of the first locker-operating part and the second locker-operating part comprises an electromagnet and a switching member adapted to switch the first locker and the second locker to a first state and a second state as the electromagnet is turned on and off.
