Abstract:
A gripping system which is monitored based on CEMF and a method for controlling the same includes: using a controller to instruct a drive unit to rotate a stepper motor; using the controller to compare the control instruction with a control parameter matrix stored in an access unit; obtaining a CEMF threshold by checking the position of the actual CEMF in the control parameter matrix; using the controller to continuously monitor the actual CEMF; and using the controller to compare the actual counter electromotive force with the obtained corresponding counter electromotive force threshold, stopping the stepper motor and letting the gripper maintain the gripping status when the actual counter electromotive force is smaller than or equal to the counter electromotive force threshold, and maintaining driving of the stepper motor when the actual counter electromotive force is larger than the counter electromotive force threshold.
