An improved device and method for performing accurate mobile robot dead-reckoning by performing Internal Position Error Correction (IPEC) which corrects systematic as well as non-systematic dead-reckoning errors. A first variation utilizes a smart encoder trailer which adapts an existing dead-reckoning mobile robot. A second variation provides a pair of robotic vehicles coupled with a compliant linkage which monitors relative positioning between the vehicles in order to perform internal position error correction. A third and final variation utilizes a pair of decoupled mobile robotic vehicles, each performing dead-reckoning, further provided with individual transmitter and receiver arrays which determine relative positioning therebetween in order to perform internal position error correction. |
