20120175175 | INVERTED PENDULUM TYPE VEHICLE - The present invention provides an inverted pendulum type vehicle which can perform a turning movement with ease without requiring any additional device even though the vehicle is configured to travel on a single drive wheel. A substantially vertical principal axis of inertia of the vehicle is tilted rearward with respect to a plumb vertical line. As result, when a rider shift his gravitational center in either lateral direction and tilts the vehicle in the corresponding direction, the main wheel is caused to turn around the principal axis of inertia so that the main wheel is steering in effect, and the vehicle can be turned in a desired direction. | 07-12-2012 |

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 |
