To be fair, there is a valid reason to attempt such a heady robotic task, as a personal care ‘bot with RoboWig's brushing skills could be very useful to someone who has a hard time performing physical tasks, for instance eldery or disabled people. According to an MIT CSAIL article, nurses spend somewhere between 18 to 40 percent of their time on “direct patient care tasks,” such as hair brushing. So you can see where such a ‘bot could come in handy. Obviously, creating a skilled brusher ‘bot is no small task, considering you have to have a robot that can gauge force so as to comb through tangles, but not painfully pull out all your hair. To accomplish as much, scientists equipped a robotic arm with a sensorized soft brush and a camera, which basically allows it to “see” curls and assess the most delicate and time-efficient way to brush them out.
