Abstract
A method for cancelling vibration includes receiving, from a first accelerometer, a first accelerometer measurement; receiving, from a second accelerometer, a second accelerometer measurement; determining a counter torque value based on the first accelerometer measurement and the second accelerometer measurement; and selectively controlling a lift mechanism according to the counter torque value using a motor, the motor being in mechanical communication with the lift mechanism and the lift mechanism being configured to allow a platform to travel in one of a first direction and a second direction.
