Abstract
According to one embodiment of the present disclosure, a surgical device is disclosed. The surgical device includes a motor and a transmission assembly movable by the motor. The surgical device also includes a force sensor configured to measure force imparted on the transmission assembly. The device may also include a controller configured to: control the motor to move the transmission assembly to a starting position, interrogate the force sensor to receive a sensor signal, compare the sensor signal to a threshold, and determine whether the force sensor is faulty based on the comparison of the sensor signal to the threshold.
