    摘要: A system includes a moveable element adapted to move relative to a coordinate system defined for a robot, an object detection transceiver unit adapted to be mounted on the moveable element, and a controller. The controller controls the object detection transceiver unit to emit a signal and obtain a return signal for an operational cell of the robot at each of a series of predetermined positions to emulate a transceiver aperture larger than an aperture of the object detection transceiver unit. A location corresponding to a marker present in the operational cell is determined from the return signals. A predetermined operation is carried out where the predetermined operation includes using the determined location to guide movement of the robot.

    摘要: A method of determining the location of the first object (10) may include receiving signals at a second object (20) from a plurality of measurement points (11) on the first object (10), estimating locations of the plurality of measurement points (11) on the first object (10), determining an estimate of a location of the first object (10), determining a first measurement of an orientation of the first object (10) based on the estimating of the locations of the plurality of measurement points (11) on the first object (10), and determining a second measurement of the orientation of the first object (10) based on measurements by an orientation sensor (12) on the first object (10). The method may include estimating an error of the estimate of the location of the first object (10) based on a difference between the first and second orientation measurements and adjusting a movement of the second object (20) based on the estimated error.
