                 robotics faces a 'chicken and egg' problem: learning to
                 control a complex body is dominated by problems
                 specific to its sensors and effectors, while building a
                 body that is controllable assumes the pre-existence of
                 a brain. The idea of co-evolution of bodies and brains
                 is becoming popular, but little work has been done in
                 evolution of physical structure because of the lack of
                 a general framework for doing it. Evo-lution of
                 creatures in simulation has usually resulted in virtual
                 entities which are not buildable, while embodied
                 evolution in actual robotics is constrained by the slow
                 pace of real time.

                 The work we present takes a step in the problem of body
                 evolution by applying evolutionary techniques to the
                 design of structures assembled out of elementary
                 components which stick together. Evolution takes place
                 in a simulator which computes forces and stresses and
                 predicts stability of 3- dimensional brick structures.
                 The final printout of our program is a schematic
                 assembly, which is then built physically. We
                 demonstrate the functionality of this approach to robot
                 body building with many evolved artifacts.",
