Conclusion The chapter covered the evolutionary morphology of actual robots using a 3-D simulator. An individual fitted for plane movement using Messy GA rotated its body by extending the leg parts in a direction perpendicular to the rotation axis to increase stability. The individual that fitted itself to the ascending stairs by GP adjusted well to the stair gap by extending the support on the back of the body in a flat and a hook shape. Either shape is typical of blocktype robots but uncommon for humans and reflects the versatility of blocks as a basic unit. A future issue will be to apply to more complicated tasks or multi-agent cooperation using modular robotics. 8.
