    摘要： Disclosed herein is a mobile robot (100) which is capable of accurately calculating a position of the wireless signal source (10) using a wireless signal, and allowing the mobile robot to accurately and rapidly return to a charging-stand using the calculated position. The position calculation system for a mobile robot includes: a wireless signal source for outputting a wireless signal continuously or periodically; and a mobile robot which includes a plurality of directional antennas (160) for detecting the wireless signal outputted through the wireless signal source, wherein, the mobile robot calculates a direction of the wireless signal source via a rotation angle detected by the directional antennas, and calculates a distance separated from the wireless signal source using a wireless signal detection time difference between the directional antennas.

    摘要： The present invention relates to a drive unit (10) comprising a rolling means (12) intended to be infrictional engagement with a surface over which said drive unit (10) is intended to move. The drive unit (10) also comprises a first driving means (14) and a second driving means (16), co-operatively operable to provide both propulsion and steering of said drive unit (10) while eliminating slippage between said rolling means (12) and said surface. The first driving means (14) is arranged on a rotatable support means (18) rotatable about a center axis (c.a.) and is operable to rotate said rolling means (12) about a roling axis. The rolling means (12) is displaced a predetermined distance from said center axis (c.a.), and the second driving means (16) is operable to rotate the support means (18) about said center axis (c.a.).

    摘要： A method for guiding a vehicle towards a target object from a remote control center over a time lagged communication channel comprises a periodic capture, time stamping and storage of frame images taken by a camera at the vehicle and a transmission of time stamped full or partial from data (global motion parameters) to the remote control center. At the control center the images are reconstructed and displayed using the frame and the time stamp data. An operator performs a target selection by marking a target point on a specific displayed frame. The coordinates of the target point and the time stamp of the specific frame are relayed back to the vehicle. At the vehicle the selected target position as appearing on information stored at the vehicle by fast forward transformations using the global motion parameters. After determination of the current target position the target object is automatically tracked by the vehicle guidance system.
