Abstract

In various embodiments, a zero-turn radius robotic base may comprise a substantially rectangular (e.g., rectangular) base portion that comprises a plurality of wheels. In various embodiments, the plurality of wheels are configured to support the robotic base adjacent a support surface (e.g., the ground, a suitable flooring surface within a building, etc.). In some embodiments, the robotic base comprises a first and second driving wheel and a plurality of stability wheels. In some embodiments, an axis of rotation of the first and the second driving wheel are collinear. In various embodiments, the plurality of stability wheels are spaces apart from the axis of rotation of the first and second driving wheels to provide stability to the robotic base.

Dependent claims

A zero turn-radius robotic base comprising:

a substantially rectangular base frame;
a plurality of stability wheels disposed adjacent an outer face of the substantially rectangular base frame;
a first driving wheel disposed at least partially within the substantially rectangular frame;
and
a second driving wheel disposed at least partially within the substantially rectangular frame and spaced apart from the first driving wheel, wherein:
the first driving wheel is spaced apart from a center of rotation of the substantially rectangular base frame and has a first axis of rotation that intersects the center of rotation;
the second driving wheel is spaced apart from the center of rotation of the substantially rectangular base frame and has a second axis of rotation that intersects the center of rotation;
and
the first axis of rotation is substantially colinear with the second axis of rotation.
