| Abstract: |
| UWB (Ultra Wide Band) is a new type of wireless communication technology with characteristics of rapid transmission, low power consumption and so on. By means of UWB,
sub-meter
level positioning can be achieved. Recently, positioning based on UWB has been widely used in the field of robots. Given that the positioning accuracy decreases rapidly at the edge of effective area of UWB, or in the situation of the signal block, a new method of UKF(Unscented Kalman Filter) combined positioning based on UWB and dead reckoning is proposed. It affords a stable and reliable approach for indoor robot localization for the sake of overcoming the shortcomings of UWB positioning mentioned above. |
