Reaching into your pocket to retrieve your phone seems like no big deal. For a robot, however, it is. Like many routine gestures that we take for granted, it’s actually very complex. Doing so requires large movements from the arm, followed by the hand’s finer motions to grasp and pull the phone out.
The prosthetics industry is too focused on high-tech limbs that are complicated, costly, and often impractical
When we pick something up, we’ll often jostle it around a bit, searching to get the best grip. A team of researchers have now developed a robotic hand that does something similar - a breakthrough that could advance the field of assistive robots.
05/12/2021 Humans use all surfaces of the hand for contact-rich manipulation. Robot hands, in contrast, typically use only the fingertips, which can limit dexterity. In a new study from the lab of Aaron Dollar, professor of mechanical engineering & materials science & computer science, researchers took a non-traditional approach to creating a new design for robotic hands. The research team - graduate students Walter Bircher and Andrew Morgan, and Dollar - designed a two-fingered dexterous hand. Known as “Model W,” it was inspired by the high levels of dexterity seen in humans’ hand mo...
