Abstract:
A robotic gripping device is provided. The robotic gripping device includes two opposable fingers and an actuator having a motor and a shaft, wherein the shaft is coupled to a first finger. The robotic gripping device also includes a torsion spring surrounding the actuator, the torsion spring having first and second ends, wherein the first end is coupled to the motor of the actuator and the second end is coupled to a second finger. Further, the actuator is configured to rotate the shaft relative to the motor by a first amount to move the two opposable fingers toward each other to contact the object. The actuator is also configured to further rotate the shaft relative to the motor to wind up the torsion spring when the two opposable fingers are both in contact with the object and the object prevents the fingers from further movement toward each other.
