Abstract
A vehicle includes a frame, a subframe pivotably coupled to the frame, a first wheel and a second wheel coupled to the subframe, and a drive motor coupled to the subframe and configured to drive the first wheel to propel the vehicle. The subframe is configured to pivot relative to the frame to maintain contact of the first wheel and the second wheel with a ground surface.
Claims20
A vehicle comprising:
- a frame;
- a subframe pivotably coupled to the frame;
- a first wheel and a second wheel coupled to the subframe;
- and
- a drive motor coupled to the subframe and configured to drive the first wheel to propel the vehicle, wherein the subframe is configured to pivot relative to the frame to maintain contact of the first wheel and the second wheel with a ground surface.

A vehicle comprising:
- a frame;
- a first drive module including:
- a first subframe pivotably coupled to the frame;
- a first caster coupled to the first subframe;
- a first drive wheel rotatably coupled to the first subframe;
- a first biasing element coupled to the first subframe and configured to bias the first subframe to rotate about a first lateral axis to direct the first drive wheel toward a ground surface;
- and
- a first drive motor coupled to the first subframe and configured to drive the first drive wheel;
- and
- a second drive module including:
- a second subframe pivotably coupled to the frame;
- a second caster coupled to the second subframe;
- a second drive wheel rotatably coupled to the second subframe;
- a second biasing element coupled to the second subframe and configured to bias the second subframe to rotate about a second lateral axis to direct the second drive wheel toward the ground surface;
- and
- a second drive motor coupled to the second subframe and configured to drive the second drive wheel, wherein the first drive wheel and the second drive wheel are configured to rotate independently in opposite directions to turn the frame about a substantially vertical axis extending within an outer perimeter defined by the frame.
