%T Abstractions for Simplifying Planning in Self-Reconfigurable Robotic Systems %A Craig McGray %A Daniela Rus %R Technical Report PCS-TR98-342 %I Dartmouth College, Computer Science %C Hanover, NH %D October 1998 %U http://www.cs.dartmouth.edu/reports/TR98-342.pdf %X In [KVRM], we described a three-dimensional self-reconfiguring robot module called the Molecule Robot. In this paper, we provide a system of abstractions for modules in self-reconfigurable robotic systems, and show how this system can be used to simplify the motion planning of the Molecule Robot system.
