20080201014 | Robot and method for controlling the same - A robot includes: a main body; a traveling mechanism attached to the main body to move the main body; an image pickup device which picks up an image of an object in a space including a traveling plane; an object detector which detects the object existing in the space based on an image picked up by the image pickup device; a distance calculator which calculates a distance to the object detected by the object detector; a degree of caution setting device which sets a degree of caution with respect to the object detected by the object detector based on the image picked up by the image pickup device and the distance calculated by the distance calculator; and a controller which controls the traveling mechanism based on the degree of caution set by the degree of caution setting device and the distance calculated by the distance calculator. | 08-21-2008 |
20080231222 | WHEELED MOVING ROBOT - A wheeled moving robot including a main body; wheels provided at least at opposite sides of the main body and configured to move the main body; an actuator configured to generate torque which rotates the wheels; a detector configured to detect whether the main body moves when the wheels rotates by the actuator; and a compensation unit configured to perform an auxiliary movement which pushes an auxiliary wheel in front or rear of the main body toward a floor based as a detection result of the detector. | 09-25-2008 |
20090052740 | MOVING OBJECT DETECTING DEVICE AND MOBILE ROBOT - A moving object detecting device measures a congestion degree of a space and utilizes the congestion degree for tracking. In performing the tracking, a direction measured by a laser range sensor is heavily weighted when the congestion degree is low. When the congestion degree is high, a sensor fusion is performed by heavily weighting a direction measured by a image processing on a captured image to obtain a moving object estimating direction, and obtains a distance by the laser range sensor in the moving object estimating direction. | 02-26-2009 |

20160137435 | TRANSFER APPARATUS AND ARTICLE TAKING-OUT METHOD - According to an embodiment, a transfer apparatus includes a gripper, a first driving mechanism, an elastic passive joint part, a conveyor, a second driving mechanism, and base. The gripper grips an article. The first driving mechanism linearly moves the gripper in at least two directions including a first direction and a second direction intersecting with the first direction. The elastic passive joint part is interposed between the gripper and the first driving mechanism, and operates in accordance with an operation of the gripper. The conveyor conveys the article. The second driving mechanism linearly moves the conveyor in the at least two directions, and is connected to the conveyor. The base supports the first driving mechanism and the second driving mechanism. | 05-19-2016 |
