US Patent 11001298 Spherical wheel drive and mounting

Implementations relate to a spherical wheel drive and mounting. In some implementations, a wheel mechanism includes a spherical wheel, a base, and a rotary bearing coupled to the base and contacting a surface of the spherical wheel, where the rotary bearing configured to allow the spherical wheel to rotate. The wheel mechanism includes an omni wheel coupled to the base and engaged with a surface of the spherical wheel, and an actuator coupled to the base and to the omni wheel, where the actuator configured to rotate the omni wheel to cause rotation of the spherical wheel.
