Finger of robotic hand and robot having the same
First Claim
1. A finger of a robotic hand, comprising:
- a phalanx portion comprising at least two phalanxes rotatably coupled to each other;
a driving device comprising a rotating member,a connection assembly comprising;
a housing defining a sliding groove that comprises a first end and a second end defining a through hole that is in communication with the sliding groove;
a cap connected to the housing at the first end;
a sliding rod comprising a base slidably received in the sliding groove and a rod protruding from the base, the rod passing through the through hole of the second end and being connected to the rotating member in such a way that rotation of the rotating member drives the rod to move along the sliding groove; and
an elastic member received in the sliding groove and comprising two opposite ends that respectively abut against the base and an inner surface of the second end, the elastic member being configured to be deformed and push the housing to move;
a rope comprising two opposite ends respectively connected to the cap and one of the at least two phalanxes, the rope being configured to pull the one of the at least two phalanxes to rotate when pulled by the housing.
