    Abstract: The present invention relates to a mobile robot having jump function. An exemplary mobile robot according to an embodiment of the present invention includes a robot body, a pair of wheels, a driving motor, a leaf spring, and a leaf spring control unit. The pair of wheels are rotatably connected to the robot body. The driving motor drives the pair of wheels so as to move the robot body. The leaf spring has a fixed end fixedly connected to the robot body and a free end disposed to face the fixed end in a state of being apart from the robot body. The leaf spring control unit applies force for bending the leaf spring such that the free end of the leaf spring is pulled toward the robot body and then removes the force applied to the leaf spring such that the leaf spring returns to an original state.

  • Publication number: 20100121538
    Abstract: A two-wheel vehicle having a roll axis rotation flexibility in which a servo motor is mounted to each of two wheels operating independently of each other fails to perform stable straight-forward traveling on a laterally inclined road because a neutral position by a spring force of a handle or a step varies with respect to a vertical axis as a vehicle body tilts in a roll axis direction due to a road slope. Further, in such a device, the handle or the step can tilt against intention due to a left and right unbalanced load of a passenger onto the step when getting on or off the vehicle. There is thus provided a control device that enables stable straight-forward traveling while maintaining a standing posture of a person vertically on a laterally inclined road through a motor control of the position of a handle or a step. There is also provided a control device that enables a rotation while a person maintains a vertical posture when a performing rotation operation on an inclined road.

    Abstract: A transverse two-wheeled vehicle has an increased turning limit value. A turning limit estimation system obtains a turning limit value and a center-of-gravity position adjustment system improves the obtained turning limit value. The turning limit estimation system obtains values for turning limit and turning stability by estimating a center-of-gravity position and a lateral acceleration. In the center-of-gravity position adjustment system, the turning limit value is increased by causing the estimated center-of-gravity position to move toward a centripetal direction. The mechanism for moving the center of gravity to is one or more of i) a vehicle body tilt mechanism, ii) a weight movement mechanism, and iii) a seat parallel movement mechanism. Accordingly, particularly a vehicle with two wheels narrowly spaced and a high center of gravity, can make a faster and smaller turn, and driving performance, stability, and security of the turning operation are improved.

  • Publication number: 20080147281
    Abstract: A two-wheel vehicle having a roll axis rotation flexibility in which a servo motor is mounted to each of two wheels operating independently of each other fails to perform stable straight-forward traveling on a laterally inclined road because a neutral position by a spring force of a handle or a step varies with respect to a vertical axis as a vehicle body tilts in a roll axis direction due to a road slope. Further, in such a device, the handle or the step can tilt against intention due to a left and right unbalanced load of a passenger onto the step when getting on or off the vehicle. There is thus provided a control device that enables stable straight-forward traveling while maintaining a standing posture of a person vertically on a laterally inclined road through a motor control of the position of a handle or a step. There is also provided a control device that enables a rotation while a person maintains a vertical posture when a performing rotation operation on an inclined road.

    Abstract: A center of gravity (C/G) control system for a vehicle includes sensors to measure the center of gravity shift and mass shift of the human body in relation to the vehicle, a controller to determine outputs, a dynamically adjustable vehicle system, and a power supply. The sensor measures the direction and rate of shift of the center of gravity and mass shift of the human and creates a representative input signal. The controller determines the appropriate outputs in response to the relative center of gravity shift data received. The dynamically adjustable vehicle system receives the controller output and performs the expected action.

  • Patent number: 7056185
    Abstract: A wireless remote controlled rover (100) having a circular outer boundary when viewed in profile, comprising an elongated round-profile frame (20) outfitted with a pair of omnidirectional wheels (101L,R), rotatable in opposite directions by a drive system (50), for steering. Each of omnidirectional wheels (101L,R) comprises a set of secondary wheels (150L,R) akin to large diameter hollow flexible shafts arcuately bent and distributed in a polar array about corresponding hubs (82L,R). The secondary wheels (150L,R) are rotatable by the drive system (50) for longitudinal thrust of rover (100). A user controls the steering and thrust actions via remote control (166) for navigation and to compensate for incidental inertial rolling/careening effects of the two-wheel round-profile rover (100) while in motion. An onboard intelligent electronic processing unit (33) uses sensory feedback for autopilot, or assistive navigation, during certain scenarios such as performing user-requested optimum stopping maneuvers.
