Moving heavy loads has now become a breeze for cleaners and workers in the logistics sector, after Hong Kong researchers invented a motorized trolley equipped with artificial intelligence (AI).In addition, the trolley will significantly reduce the risk of work-related injuries.

Users of the electronic power-assisted trolley can manoeuvre it fully loaded as if it were empty by simply holding onto its handlebar. The trolley employs sensors to measure the pressure of the user's grip on the handlebar, as well as an onboard AI controller to calculate the required torque, the twisting force that causes rotation. Two electric motors in the wheel generate force to overcome the weight of the trolley, allowing users to steer a fully loaded vehicle with ease.

Researchers said their aim is to help workers handle heavy loads and reduce the risk of musculoskeletal disorders and work-related injuries. The prototype is being tested by a cleaning company, where it is helping staff transport equipment for street-cleaning work.

The trolley is among multiple research projects being funded by the government's InnoHK initiative, which set up 28 research centers focused on developing solutions for different industries.
