Sensorial Interference Avoidance by Multi Mobile Robot Sensor Coordination

One way to automate dangerous work at construction sites could be to use mobile robots able to move around the framework of a building or a road. This paper presents an algorithm, which permits synchronization of active sensors, such as ultrasonic sensors, IR, laser, etc., firing and reception of signals in the presence of several mobile robots working in the same environment. These sensors base their measurement on the transmission and reception of signals; these can interfere mutually giving rise the erroneous measurement. The proposed algorithm is intended to eliminate this interference between signals fired from different robots operating in the same zone, establishing a firing sequence. Various experimental results show the effectiveness of the presented method.
