The article analyzes the technical characteristics, advantages, limitations, and selection logic of AGV drive wheels, steering wheels, and casters, explaining how these three core mobility components determine AGV precision, flexibility, load capacity, and overall system performance.

The AGV horizontal drive steering wheel features an integrated design that combines a steering motor, reduction transmission mechanism, position feedback unit, limit device, and rotary mechanism into a single compact module. When equipped with a drive controller, a mobile platform configured with a single steering wheel can perform start/stop, forward and backward movement, and steering functions. When two or more steering wheels are used, the system enables zero-radius rotation, lateral movement, omnidirectional 360° rotation, straight-line travel, sideways motion, diagonal movement, and curved trajectories—allowing free movement in any direction on a two-dimensional plane.
