Abstract
The systems and methods are directed to mechanical arms and manipulators, and more particularly, to optical distance sensors in use for approach, grasping and manipulation. The system may include a manipulator having an arm and a multi fingered end-effector coupled to the distal end of the arm. The end-effector may include an optical proximity sensor configured to detect the distance to an object prior to contact with the object. The end-effector may include an optical proximity sensor configured detect a measurement of force applied to the object by the manipulator post contact with the object. The measurement of force may be a range of force measurements including a minimum, a maximum and a measurement between or within the minimum and the maximum.
