No photos have been taken in CC15: piston wheel (NOT a wheel).
Well done, a complete new way of moving, no wheels, no traditional legs, no uncreative sliding (Like mine XD), just pure, simple and effective kick action of the pistons, nice work.
very cool idea, very creative mechanism! you should continue working on it so it gets possible to go on different speed or to jump with the pistons - then it would be even greater! you could try speed scale on the pistons release time f.e.. then this "wheel" could get over bigger obstacles...
you have quite a skill with contraptions
