  abstract =     "Creating artificial life forms through evolutionary
                 robotics faces a {"}chicken and egg{"} problem:
                 learning to control a complex body is dominated by
                 inductive biases specific to its sensors and effectors,
                 while building a body which is controllable is
                 conditioned on 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. Evolution of
                 creatures in simulation has been constrained by the
                 {"}reality gap{"} which implies that resultant objects
                 are usually not buildable.

                 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 parts. Evolution
                 takes place in a simulator we designed, which computes
                 forces and stresses and predicts failure for
                 2-dimensional Lego structures. The final printout of
                 our program is a schematic assembly, which can then be
                 built physically. We demonstrate its functionality in
                 several different evolved entities.",
