Engineers at the University of California San Diego developed a new approach allowing a robotic hand to rotate objects solely through touch. The UCSD method enables a robotic hand to do so without relying on vision. Using their technique, the engineers built a hand that can smoothly rotate a range of objects, including small toys…

University of California San Diego engineers have prototyped an inexpensive device that clips onto a smartphone to monitor a user’s blood pressure. The 3D-printed device uses the smartphone’s camera and flash paired with an algorithm on an app to take systolic and diastolic blood pressure readings. “We’ve created an inexpensive solution to lower the barrier…
