A motorized personal transport utility vehicle comprises a frame, independent front and rear suspension and a plurality of wheel hubs. Each suspension arm is pivotally coupled to a central frame portion. A pair of front wheel hubs are coupled to the front suspension arms and a pair of rear wheel hubs are coupled to the rear suspension arms. Each of the wheel hubs includes an integrated electric hub motor. The front and rear suspension arms are configured such that the front wheel hub track width is greater than the rear wheel hub track width such that the inner width between the insides of the front wheel hubs is greater than the outer width between the rear wheel hubs.

A robot has an electronic surveillance system embedded within a chassis disposed between two wheels. The wheels include a main body and a plurality of treads. The treads are generally disposed radially around the main body and extend distally from outer portion of the main body. The main body generally defines a plurality of compression cells and may present a substantially frustoconical outer surface.

A two wheeled throwable robot comprises an elongate chassis with two ends, a motor at each end, drive wheels connected to the motors, and a tail extending from the elongate chassis. A rear portion having a deep recess securing the pair of motors with brackets, and batteries with brackets. The forward part having a shallow recess with a printed circuit board secured therein having control circuitry. The wheels are less than six inches in diameter and the robot weighs less than five pounds.

A vehicle platform with positioning and guiding mechanisms and having a single wheel. A frame extends from the vehicle with a receptacle connected to the frame, and a motor drives the vehicle forward and rearward. A head appendage is mounted to the receptacle to yaw left and right, pitch up and down, and roll from side to side to guide the vehicle. Another motor provides for positioning the appendage to roll, with an additional motor for positioning the head to pitch and yaw. A pair of left and right rims is disposed adjacent to the wheel for limiting lean of the vehicle platform, and a control system is incorporated.

A four-wheeled articulated steering vehicle for terrain exploration. The four-wheeled articulated steering vehicle has a pair of robotic tethered two-wheel vehicles that dock, lock, and drive long distances as the four-wheeled, articulated steering vehicle. Two actuated docking mechanisms attached on opposite ends of a central module of the four-wheeled vehicle enable sit/stand functionality. The sit configuration is achieved by aligning each dock mechanism parallel or nearly parallel to the surface, allowing two-wheel vehicle to detach and explore while the other remains docked and serves as a backup. While sitting, the central module rests on the ground and is outfitted with shovel-style wedges for passive anchoring. In order to stand, the exploring two-wheel vehicle reattaches, locks, and both dock mechanisms are rotated until each two-wheel vehicle's caster arm is upright and the central module is lifted off the ground. Once upright, each two-wheel vehicle rotates about a pivot point for articulated, all-wheel steering, which is accomplished by applying differential wheel torques.

According to an embodiment of the present disclosure, a mobile robot may include an outer cover including an insulating material and defining an appearance; an inner cover including an insulating material and configured to define a predetermined gap with respect to the outer cover; a battery disposed inside the inner cover; and at least one pressure sensing module disposed in the gap between the outer cover and the inner cover. The pressure sensing module may include an outer metal panel contacting an inner periphery of the outer cover, an inner metal panel contacting an outer periphery of the inner cover and spaced apart from the outer metal panel, and a pressure sensing sheet pressed between the outer metal panel and the inner metal panel and having a variable resistance. The battery may generate an electric potential difference between the outer metal panel and the inner metal panel.
