Mechanical fingers for dexterity and grasping

摘要

Improved robotic fingers are disclosed. The present invention provides a novel three joint, two actuator robotic finger. The finger disclosed is self-contained, lighter and requires less computational overhead than designs requiring one actuator for each joint, while providing greater versatility than simple grippers. The fingers of the present invention are constructed using a series of pulleys and tendons to couple the motion of two joints. In a preferred embodiment, a novel tendon configuration is disclosed which provides human-like enclosure and grasping capabilities. Also, other useful tendon configurations are disclosed. Robotic hands comprised of a group of one or more of the fingers of the present invention and methods of utilizing them to manipulate objects are also disclosed.
