Disclosed is a method and apparatus for controlling mobility of a trolley. The apparatus may be attached to the trolley at the bottom. The apparatus may comprise an anti-skid surface and a controlling means to control the movement of the anti-skid surface. The anti-skid surface may be enabled to move vertically downward and upward, via the controlling means, thereby arresting mobility of the trolley. The downward movement of the anti-skid surface may facilitate contact between the anti-skid surface and floor thereby arresting the mobility, whereas the upward movement of the anti-skid surface may restore the mobility by disconnecting the contact between the anti-skid surface and the floor.
