Electronic Power Assist Trolley System
This is an electronic power assist trolley system with an intuitive control scheme. Sensors are strategically embedded in the trolley handlebar to measure the micro deformation of the materials when force is applied by the user. The torque vector is calculated 100 times per second based on the sensor's value by an onboard AI controller. Amplified torque is generated by two motors connected to the wheels of the trolley. Turning left/right or forward/backward depends on the calculated torque vector. The manoeuvre of this power assist trolley is the same as a traditional mechanical trolley without buttons, joysticks and controllers. No prior training is required when using the trolley and it can be manoeuvred like an empty trolley even if it is heavily-loaded. The built-in power regeneration and brake system make it safe for use even on a ramp.
This system has won a Gold Medal in the 48th International Exhibition of Inventions of Geneva.
