Abstract
A robotic vehicle chassis is provided. The robotic vehicle chassis includes a first chassis section, a second chassis section, and a hinge joint connecting the first and second chassis sections such that the first and second chassis sections are capable of rotation with respect to each other in at least a first direction. The vehicle includes a drive wheel mounted to one of the first and second chassis sections and an omni-wheel mounted to the other of the first and second chassis sections. The omni-wheel is mounted at an angle orthogonal with respect to the drive wheel. The hinge joint rotates in response to the curvature of a surface the vehicle is traversing.

A robotic vehicle chassis for a two-wheeled robotic vehicle, comprising:
- a first chassis section;
- a second chassis section;
- a hinge joint connecting the first and second chassis sections such that the first and second chassis sections are capable of rotation with respect to each other in a first direction;
- a drive wheel mounted to one of the first and second chassis sections, wherein the drive wheel includes first and second drive hubs, each respective hub being located on an opposite side of the drive wheel, the first and second drive hubs being configured to rotate together or with respect to each other, and wherein the drive wheel has a curvature such that each side of the drive wheel contacts the surface at a single point located on a respective opposite side of the curvature;
- an omni-wheel mounted to the other of the first and second chassis sections;
- the omni-wheel being mounted at an angle orthogonal with respect to the drive wheel;
- at least a first magnet included in the drive wheel;
- and
- at least a second magnet included in the omni-wheel,
- wherein the at least first and second magnets maintain an attractive force between the drive wheel and the surface and the omni-wheel and the surface, respectively, wherein the surface is ferromagnetic,
- wherein the hinge joint rotates in response to the curvature of a surface the vehicle is traversing.

- an omni-wheel mounted to the other of the first and second chassis sections;
- the omni-wheel being mounted at an angle orthogonal with respect to the drive wheel;
- a spring element extending between the first and second chassis section, the spring element providing a force that urges the first and second chassis sections into a normal position in which there is a zero degree of rotation between the first and second chassis sections;
- at least a first magnet included in the drive wheel;
- and
- at least a second magnet included in the omni-wheel,
- wherein the at least first and second magnets maintain an attractive force between the drive wheel and the surface and the omni-wheel and the surface, respectively, wherein the surface is ferromagnetic,
- wherein the hinge joint rotates in response to the curvature of a surface the vehicle is traversing.
