One of the problems biomechatronic engineers face is making limbs that behave like normal limbs. After all, how hard would it be to walk with one normal foot and one weird one? The biomechatronics lab at MIT has developed a foot that attempts to mimic the normal behavior of a standard foot while walking over various terrain.
The foot has a rotating ankle joint attached to an artificial shin and a board-like surface for the part that touches the ground. We're always excited when we hear about advances in prosthetics, because one of our greatest fears is losing a limb in a horrific blogging accident. Don't laugh. It could happen.
