Abstract

A method of cleaning a floor near a vertical surface with a mobile robot. The robot includes a cleaning assembly and a drive assembly having a first wheel and a second wheel. The method includes aligning the robot such that the first wheel and second wheel are configured to roll in a direction substantially parallel to the surface. The method includes driving the robot forward in a direction substantially parallel to the surface. The method further includes: i) turning the first wheel, proximate to the surface, with a first angular velocity, and ii) turning the second wheel, further from the surface, with a second angular velocity. The second angular velocity is greater than the first angular velocity. The robot pushes against the surface while sliding along the same surface.
