First Claim
Patent Images
1. A roller assembly for providing collision protection and stability to a mobile robot, comprising:
- a shaft forming an axis about which the roller assembly can rotate, said shaft having opposite ends configured to be supported by bearings in the robot;
an impact absorbing layer coaxially covering the shaft; and
a shell coaxially covering the impact absorbing layer having a lower coefficient of friction than the impact absorbing layer for providing low sliding friction.

Abstract
A roller assembly provides collision protection and stability to a mobile robot. The roller assembly includes a shaft forming an axis about which the roller assembly can rotate. The shaft has opposite ends configured to be supported by bearings in the robot. The roller assembly also includes an impact absorbing layer coaxially covering the shaft. It further includes a shell coaxially covering the impact absorbing layer having a lower coefficient of friction than the impact absorbing layer for providing low sliding friction.
