This omni-directional roller mobile robot features a direction-adjustable roller conveyor top. Unlike fixed-direction roller robots, its rollers can actively change the cargo's transfer direction, enabling multi-directional (forward, backward, sideways) material movement on the robot itself. This dual flexibility—omni-wheel mobility + adjustable roller direction—allows seamless docking with conveyor lines at any angle, making it ideal for complex production lines and flexible material handling scenarios.
