There is some speculation on some cool robot designs here of course based on natures designs. Aardvarks are an interesting choice for a robot design but not without some merrit. As robots in our future become reality we should be looking at these inovative designs and testing them. Although scientists are always working on some very interesting designs like most recently testing a snake like robot that can both go on land or water. I would say this design is most efficient and may preclude us from designing some of speculative designs out there now. Althought there will always be plenty of creativity in the robotic toy industry.
