The primary function of the motor controller is to regulate the speed and direction of the wheelchair. It does this by interpreting inputs from the joystick or control panel that the user operates. When a user pushes the joystick forward, the controller receives this signal and adjusts the power sent to the motors accordingly, enabling smooth acceleration. Similarly, pulling the joystick back will reverse the motion, and turning it left or right will direct the motors to turn the wheelchair in the desired direction.

Another essential feature is the ability to adjust the height of the trolley. This flexibility allows medical personnel to load and unload patients smoothly and safely, reducing the risk of injury to both the patient and staff. Additionally, a reliable braking system is crucial to secure the trolley in place during patient transfers or interventions.
