KINETIC AND DIMENSIONAL OPTIMIZATION FOR A TENDON-DRIVEN GRIPPER
A tendon-driven robotic gripper is disclosed for performing fingertip and enveloping grasps. One embodiment comprises two fingers, each with two links, and is actuated using a single active tendon. During unobstructed closing, the distal links remain parallel, creating exact fingertip grasps. Conversely, if the proximal links are stopped by contact with an object, the distal links start flexing, creating a stable enveloping grasp. The route of the active tendon and the parameters of the springs providing passive extension forces are optimized in order to achieve this behavior. An additional passive tendon is disclosed that may be used as a constraint preventing the gripper from entering undesirable parts of the joint workspace. A method for optimizing the dimensions of the links in order to achieve enveloping grasps of a large range of objects is disclosed and applied to a set of common household objects.

ROBOT
A robot includes: a moving mechanism; an elevating mechanism including columnar members; a table which is elevated and lowered by the elevating mechanism and on which various objects can be placed; an arm base which is elevated and lowered by the elevating mechanism; arms attached to the arm base; a sensor which detects an object placed on the table and the surrounding area of the robot; and a controller. A circumscribed space circumscribing the robot except for the arms is in the shape of a cuboid having a bottom face that is a face of a quadrilateral that circumscribes, in a top view, the shape of the robot except for the arms. The arms have a structure capable of accessing the outside of the circumscribed space.
