20140114559 | Inverted Pendulum Type Moving Body Having Velocity Planning Device - The present invention provides an inverted pendulum-type moving body having a pair of wheels suspended from the moving body, using a floor as a traveling plane, and is provided on the same plane vertical to its travelling direction, a driving mechanism for rotating these wheels, posture measurement means for measuring an inclination angular velocity of its upper body that a straight line connecting a center-of-gravity position of a body of the moving body and an axle of the one pair of wheels makes with a vertical direction, and a mechanism control part for maintaining an inverted state of the moving body by controlling the driving mechanism, by having a velocity planning device for performing a movement plan so that the upper body angular velocity and the upper body angle may be in a relationship of quadratic function when a velocity change is needed. | 04-24-2014 |
20140148989 | Autonomous Moving Device and Control Method Thereof - An autonomous moving device includes a travel unit with a wheel driven by a motor and an upper body including an environment-recognition sensor that detects an obstacle in a traveling direction. The upper body includes means that recognize device and obstacle positions, means that evaluates avoidance capability, and means that obtains priority of collision avoidance of an estimated passage area of the obstacle. The upper body further includes a control unit that moves the travel unit to an area where an estimated passage area of an obstacle whose priority of collision avoidance is high that does not overlap an area where the travel unit is located and which is an area where collision can be avoided even if an area where an estimated passage area of an obstacle whose priority of collision avoidance is low overlaps the area where the travel unit is located. | 05-29-2014 |
20140376780 | Method for Estimating Direction of Person Standing Still - The invention is directed to detecting a boundary position between a foot and a lower leg of a person in an image acquired by an imaging unit, the boundary position being a substantial boundary part, in a lower limb, between the foot, which is a part from a malleolus to a tip part, and the lower leg; detecting a feature quantity that makes it possible to classify a ground and a part other than the ground in the image; setting, in a peripheral region around the boundary position, a plurality of local regions having positional information and/or direction information relative to the boundary position, and determining whether each of the local regions is the ground or the part other than the ground by using the feature quantity unique to the ground; determining a foot region from the local region determined as the part other than the ground; and estimating a direction of the foot of the person from the local region classified as the foot region and from the information. | 12-25-2014 |
20140379198 | Mobile Object - The present invention provides a mobile object capable of stable movement and jumping. The mobile object includes two moving means attached to left and right sides under a body; a sensor to detect attitude of the body; a controller to receive information from the sensor and perform calculation; two telescopic actuators attached between the body and the two moving means and configured to generate vertical forces; a rotary actuator provided at the center of the two telescopic actuators and configured to rotate around a moving direction of the body; a roll link connected with an output part of the rotary actuator; two suspensions connecting left and right ends of the roll link and the moving means; and foot frames attached between the suspensions and the moving means, wherein the controller controls the rotary actuator so that the sensor detects a target tilt angle and a target angular velocity of the body. | 12-25-2014 |
20150027801 | MOVING BODY - The moving mechanism is capable of separating an orientation of a vehicle body from a traveling direction. In addition, the moving mechanism has a low center of gravity and is capable of reducing its weight. A moving body includes a vehicle body, steering actuators, right and left steering hubs, vehicle wheel actuators, and vehicle wheels. The steering actuators are disposed on the right and left sides of the vehicle body and drivable around a vertical axis. The right and left steering hubs are driven by the steering actuators. The vehicle wheel actuators are fixed to the steering hubs. The vehicle wheels are driven by the vehicle wheel actuators and are disposed in an inclined manner with respect to a vertical direction. | 01-29-2015 |
