ROX-Diff

The central differential drive is one of the most common kinematic configurations in AMRs, along with the three-wheel setup. It consists of two independently controlled drive wheels, which are mounted on the left and right corners of the platform center. The actual load is supported by passive steering casters, one at each corner of the platform in the case of the ROX.

This configuration offers several advantages:

• It is a cost-effective and energy-efficient drive system.
• The ability to rotate in place provides the robot with high mobility, even in confined spaces.
• Thanks to its suspension system, the robot can easily navigate small steps and gaps and can handle most industrial floor surfaces with ease.

On the other hand this design comes with very few limitations:

• For applications with high shear or lateral forces, the ROX-Trike or ROX-Argo would be more suitable.
