  • Patent number: 7963351
    Abstract: A method for forming a robotic vehicle. The method may involve forming a body and arranging a plurality of movable legs to project from the body for propelling the body over a surface. An actuator may be carried by the body to selectively engage and disengage different ones of the movable legs to cause a motion of the body, and thus the robotic vehicle, to travel over the surface.

  • Patent number: 7743858
    Abstract: A vehicle (for example an unmanned robot vehicle) which includes a main body provided with a main locomotion mechanism for traveling over a terrain. The device is provided with at least one arm for enhanced support and maneuverability, the arm pivotally attached to the main body. The arm is controllable and capable of being rotated to a position where the arm or at least a substantial portion of the arm is placed in contact with the terrain or obstacle, so as to provide support or leverage to the main body.

  • Patent number: 7490681
    Abstract: A robotic vehicle having a body with an internal volume. A plurality of extendable legs project outwardly from the body for supporting the body on a surface and for propelling the body, in at least a partial rolling motion, over the surface. A gimbal system is supported within the body. The gimbal system has a support platform that is moveable within at least two non-parallel planes. An actuator is supported on the support platform and is positionable by the gimbal system into different positions to actuate selected ones of the extendable legs, to thus assist in propelling the vehicle.

  • Patent number: 6422329
    Abstract: A human assisted walking robot formed by a motor, a cargo bin, a pair of legs mounted to the carrier; and a stabilizing support mounted at its proximal end to the carrier and having a wheel rotatably mounted to the distal end. The motor drives the first and second leg members resulting in a walking motion. Each leg is formed by a thigh link and a shank link. A four-bar linkage is coupled between the motor and the thigh and shank of each leg so that rotational motion generated by the motor produces a walking motion by the legs.
