Robot capable of gripping objects

A hand grip device for a robot, the hand grip device comprising:

• a stationary finger;
• and
• a moveable finger that moves relative to the stationary finger;
• wherein the moveable finger cycles through an open and closed position as a motor rotates in a single direction, thereby allowing an object to be gripped between the stationary and moveable fingers.

A hand grip device for a robot, the hand grip device comprising:

• a stationary finger;
• a moveable finger that is moveable between an open position and a closed position, said moveable finger including a lever arm;
• a spring closure mechanism to bias the moveable finger in the closed position;
• a motor that rotates a lead screw;
• and
• a gear system attached through at least a linkage to said lever arm;
• wherein rotation of said lead screw rotates the first gear, which in turn rotates the gear system, which in turn causes the linkage to pull the lever arm thereby moving the moveable finger from the closed position to the open position.
