Robots are capable of doing many things for us already. MIT researchers have now come up with a hair combing robot that uses a sensorized soft brush and camera to get the job done. The task is difficult for robots as they need to exert strong enough force to untangle hair but not too much of it to cause pain.
This robot from MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL) and the Soft Math Lab at Harvard University can adapt to different levels of curliness. It uses a mathematical model that sees tangled hair as set of entwined double helices. You can find out more here.
