Collective construction with multiple robots

摘要

We study the problem of construction by autonomous mobile robots focusing on the coordination strategy employed by the robots to solve a simple construction problem efficiently. In particular we address the problem of constructing a linear 2D structure in a planar bounded environment. A "minimalist" single-robot solution to the problem is given, as well as two multi-robot solutions, which are natural extensions to the single-robot approach, with varying degrees of inter-robot communication. Results show that with minimal inter-robot communication (1 bit of state), there is a significant improvement in the system performance. This improvement is invariant with respect to the size of the environment.
