While the human hand, with four fingers and opposable thumb, is pretty darn awesome, it still falls woefully short when it comes to some tasks -- such as opening a soda bottle or peeling a banana. MIT, which is obviously a firm believer that we can and should enhance humans as far as physically possible, has a solution: a wrist-mounted robot that gives you two extra fingers. With the so-called "7 Finger Robot" equipped, you can both grasp a soda bottle and turn the cap at the same time. According to the MIT engineer who led the project, Harry Asada, some users might even begin to perceive the robotic helping fingers as part of their body -- like a tool you have been using for a long time, you feel the robot as an extension of your hand.
