The HRP-2m Choromet can lay down and stand-up by itself. The 35cm tall robot can also stand on one leg.
I think the same team showed in January a much taller anime inspired robot called HRP-2 Promet. The design is very similar. Only difference is that the HRP-2 is 154cm tall.The HRP-2m Choromet will cost about 500,000 yen (~$4,400).
