  • Multi-modal mobility unmanned vehicle
    Patent number: 12344407
    Abstract: In some embodiments, a multi-modal robot can be capable of aerial mobility and ground mobility, and can switch between configuration. The multi-modal robot can include a chassis, and a leg attached to the chassis. The leg can include a frontal hip joint. The frontal hip joint can rotate around a frontal hip axis of rotation. The frontal hip axis of rotation can be parallel to a longitudinal axis of the chassis. The leg can further include a sagittal hip joint, wherein the sagittal hip joint is coupled to the first distal end of a first link. The sagittal hip joint can rotate around a sagittal hip axis of rotation. The leg can include a wheel. The wheel can be configured to rotate around a wheel axis of rotation. The leg can further include a propeller. The propeller can be co-axial with the wheel.

  • Ball-balancing robot and drive assembly therefor
    Patent number: 10189342
    Abstract: A ball-balancing drive assembly includes a ball having a ball surface and a reference axis extending through a centroid of the ball. Three omniwheel assemblies, each having a motor with a motor axle and an omniwheel configured to rotate around the motor axle are mounted on a chassis configured for supporting the three omniwheel assemblies at radially symmetric spacings with the motor axles oriented at an angle relative to the reference axis and the omniwheels oriented in mutually-orthogonal planes. Each omniwheel frictionally contacts the ball surface to convert rotational motion of the motor axle to torque on the ball.
