MECHANICAL ARM

A mechanical arm designed to provide automated garbage collection with smooth, constant movement (i.e. movement that has minimal jerk/shock) thereby resulting in limited shock stress on the components and leading to high durability. The mechanical arm including a horizontal displacement system having a plurality of sections rollingly engaged to one another and a motor mounted to an immobile section for drivingly extending section in a generally horizontal orientation, a vertical displacement system having a plurality of masts rollingly engaged to one another and a motor mounted to a first mast for drivingly extending a second mast in a generally vertical orientation, and/or a grabber system having a plurality of fingers mounted to a frame and operated by a single motor.
