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.
Claims20
A system comprising:
- a manipulator having an arm and a multi-fingered, end-effector coupled to the distal end of the arm;
- wherein the end-effector comprises an optical proximity sensor configured to detect the distance to an object in response to an object entering a predetermined range of the optical proximity sensor and produce a measurement of force applied to the object by the manipulator in response to contact with the object, wherein the measurement of force is a range of force measurements including a minimum, a maximum and a measurement within the minimum and the maximum.
A method comprising:
- measuring, by an optical proximity sensor housed on an end-effector of a manipulator, a distance to an object prior to contact with the object;
- and
- measuring force applied to the object by the manipulator in response to contact with the object, wherein the measurement of force is a range of force measurements including a minimum, a maximum and a measurement within the minimum and the maximum.
An end-effector comprising an optical proximity sensor configured to detect the distance to an object under inspection and produce a scaled range of force measurements of force applied to the object subsequent to contact with the object, wherein a contact surface of the end-effector is configured to compress as force is applied to the object.
