When the hand holding the handle shell shakes, the control circuit sends control electric signals to the three motors according to the output of the IMU, and accordingly shake of the hand is compensated. The three-axis balancing algorithm on which the control circuit is based has been implemented in a number of ways known in the art and will not be described in detail here.
