Abstract: One approach to non-terrestrial construction involves the use of small, inexpensive, modular robots rather than expensive one-of-a-kind construction tools. The Modular Robots Testbed at the University of Colorado provides the means to test the software modularity and multi-robot control algorithms required for the physical manipulation of constructible elements. The testbed includes three circular, wheeled platforms. Each platform has mounted on it a high-precision positioning system, a simple manipulator, and internal/external local area digital network interfaces. Cooperation is implemented using control and data packets passed between robots and between robot components. The robots are not limited to teleoperation - they are allowed autonomous and semi-autonomous functionality to permit operation as an ensemble. The paper describes the components, software, and control strategies used in the testbed, and future expansions.
