  Evolutionary robotics has aimed to optimize robot control and morphology to
produce better and more robust robots. Most previous research only addresses
optimization of control, and does this only in simulation. We have developed a
four-legged mammal-inspired robot that features a self-reconfiguring
morphology. In this paper, we discuss the possibilities opened up by being able
to efficiently do experiments on a changing morphology in the real world. We
discuss present challenges for such a platform and potential experimental
designs that could unlock new discoveries. Finally, we place our robot in its
context within general developments in the field of evolutionary robotics, and
consider what advances the future might hold.
