Aiko is the first android to mimic pain, and reacts to it. This technology can be beneficial for people born with or who have undergone amputations. This is the first step toward a life-like mechanical limb that has the ability to feel physical sensation.There's also a Project Aiko blog. Aiko was designed and built by a robotics enthusiast in his basement.
