The present disclosure relates to a foldable electric golf trolley. When the electric golf trolley is folded, connecting rods on two sides of a frame of the electric golf trolley and wheels connected to the connecting rods are folded on the two sides of the frame. When the electric golf trolley in the present disclosure is folded, two rear wheels and connecting rods used for connecting the frame and the rear wheels can be folded on the two sides of the frame, such that an entire size of the folded electric golf trolley is effectively reduced, and the electric golf trolley is smaller in occupation space and more convenient to move and store.

A robotic surgery cart has a pair of rear wheel assemblies and a pair of front wheel assemblies. A brake assembly for the robotic surgery cart includes a gearbox interposed between and connected to the pair of rear wheel assemblies by rotatable shafts. Elongate actuators extend between and interconnect the rotatable shafts and brake mechanisms for the front wheel assemblies. A pedal lever is rotatably coupled to the gearbox and can rotate clockwise by pressing one portion of the pedal lever and can rotate counterclockwise by pressing another portion of the pedal lever. Rotation of the pedal lever causes the gearbox to rotate the rotatable shafts to substantially lock the pair of rear wheel assemblies, and substantially simultaneously causes a translation of the elongate actuators to actuate the brake mechanisms of the front wheel assemblies, such that the wheels of the front and rear wheel assemblies brake substantially simultaneously.
