Zothecula writes: Providing robots with sensory inputs is one of the keys to the development of more capable and useful machines. Sight and hearing are the most common senses bestowed upon our mechanical friends (perhaps soon to be foes?), but even taste and smell have got a look in. With the sense of touch so important to human beings, there have also been a number of efforts to give robots the sense of touch so they can better navigate and interact with their environments. The latest attempt to create a touchy feely robot comes from the Technical University Munich (TUM) where researchers have produced small hexagonal plates, which when joined together, form a sensitive skin.
