| 20090210091 | LEGGED MOBILE ROBOT AND CONTROL SYSTEM THEREOF - The legged mobile robot the foot comprises a foot main body connected to each leg, a toe provided at a fore end of the foot main body to be bendable with respect to the foot main body, and a bending angle holder capable of holding a bending angle of the toe in a bendable range of the toe. In addition, a legged mobile robot control system is configured to hold the bending angle of the toe at a first time point which is a liftoff time of the leg from a floor or earlier thereof, and to release the bending angle at a second time point after the leg has lifted off the floor to restore the toe to a initial position. With this, the bending angle at the time of liftoff can continue to be held after liftoff, whereby the robot can be prevented from becoming unstable owing to the toe contacting the floor immediately after liftoff. In addition, stability during tiptoe standing can be enhanced. | 08-20-2009 |
| 20100292837 | ROBOT HAND AND CONTROL SYSTEM, CONTROL METHOD AND CONTROL PROGRAM FOR THE SAME - A robot hand has a pipe which is sufficiently flexible to allow a change in the cross-sectional area thereof according to the pressure of a fluid, thereby permitting a higher degree of freedom of the layouts of the pipe and a master cylinder connected through the pipe. Moreover, considerations are given to a change in the cross-sectional area of the pipe caused by a change in the pressure of the fluid in the pipe, thus making it possible to measure the position of a slave piston with high accuracy. | 11-18-2010 |

| 20110067938 | INVERTED PENDULUM TYPE VEHICLE - In an inverted pendulum type vehicle having a lower frame ( | 03-24-2011 |
| 20110068738 | RECHARGING SYSTEM FOR A RECHARGEABLE BATTERY OF AN INVERTED PENDULUM TYPE VEHICLE - A recharging system for a rechargeable battery ( | 03-24-2011 |
| 20110070998 | DRIVE UNIT - A drive unit includes a main wheel having an annular member, and a plurality of driven rollers that are rotatably attached to the annular member, a plurality of first drive rollers and a plurality of second drive rollers, which are provided with the annular member between them and arranged such that they make contact with the outer peripheral faces of the driven rollers, a first holder and a second holder, which are arranged with the annular shaft between them and respectively hold the plurality of first drive rollers and the plurality of second drive rollers while allowing them to rotate, and a first drive unit and a second drive unit that rotationally drive the first holder and the second holder respectively; grooves are formed in the outer peripheral faces of the driven rollers at an angle to the circumferential direction thereof. | 03-24-2011 |
| 20110071715 | ELECTRIC VEHICLE - An electric vehicle includes a base; a front wheel that can be driven omnidirectionaly; a rear wheel that is mounted on the base so that a symmetry axis is parallel with a symmetry axis of the front wheel; a seat member that is mounted so that a straight line connecting a wheel center of the front wheel and a wheel center of the rear wheel specifies a fore-and-aft direction; an controller that detects an acceleration and deceleration command and a turning command; an inclination sensor that detects inclination of the base; and a control unit that controls acceleration and deceleration of the base based on the acceleration and deceleration command detected by the controller, that controls turning of the base based on the turning command detected by the controller, and that controls translational motion of the base based on inclination of the base detected by the inclination sensor. | 03-24-2011 |
