  • Patent number: 9796084
    Abstract: An electric gripper system includes a motor driving a gripper mechanism, a sensor, and a controller. The sensor is assembled onto the motor for generating a current position of the gripper mechanism. The controller has a control segment, a transceiver segment, an accessible segment, and a driving segment. The control segment generates a target position according to a relative-position command value of the transceiver segment and an absolute cumulative position of the accessible segment. The control segment generates a driving datum based on a difference between the current position and the target position, and on a rotation rate of the motor. The driving segment uses the driving datum to drive the motor to move the gripper mechanism. With calculation among the relative-position command value, the absolute cumulative position, and the current position, the motor is prevented from accumulating positional deviation.
