A robotic hand is provided with an array of movable spring loaded fingers and an assembly opposed to the fingers. An object to be grasped by the hand is pushed by the assembly toward and into contact with the fingers. An electrical signal is produced when each finger is contacted by the object. The time intervals between various finger contacts are measured and used to calculate the distance that the object moved during those intervals. These distances provide information about the shape of the object which can be used to differentiate between objects of various shapes.

Robot hand

A system for the automatic adjustment of the pressure pad holding force in accordance with the thickness of the workpiece and the forming tool stroke includes a force transducer and a displacement transducer. The force transducer is used to monitor the force between the pressure pad and the workpiece. The output of the displacement transducer is continually read as the part is being formed. The workpiece thickness and forming tool stroke are used to calculate the optimum holding force. The pressure of a fluid system is adjusted to change the holding force to the optimum value.

System and method for the in press adjustment of workpiece holding force

A system for the in press measurement of the thickness of a workpiece includes a force transducer and a displacement transducer. The force transducer is used to detect the contact between the forming tool and the workpiece. The output of the displacement transducer is continually read and recorded at the instant the force transducer indicates the contact between the forming tool and the workpiece. The output of the displacement transducer is correlated to known thicknesses and thus is indicative of the thickness of the unknown specimen.
