Abstract:
This work discusses the common opinion among robotics systems’ designer, assuming that for a given assignment and robotics system, enhancing the robots by increasing their physical capabilities, may only result in an improvement in the overall performance of the system (albeit small). Therefore, a designer may rely on existing designs prepared in the past, and by continuously adding resources to the robots, finally achieve the overall system’s performance he is interested in. As it can be shown, this assumption is wrong, as itmay not only lead to a zero increase in the performance, but even to a new system, comprising far more advance (and expensive) robots, which achieve much worse results than the original system. The work presents an example concerning the problem of multi-robots exploration of a graph, in which adding communication features to the robots causes the entire system’s performance to drop significantly.
