Lightweight Robotic Arm (IMAGE) Lehigh University Caption The team in Jeffrey C. Trinkle's lab work with a next-generation lightweight robotic arm designed specifically for academic and industrial research. A key feature of the arm, according to Jinda Cui, Ph.D. student and research assistant, is that it has "seven degrees of freedom," or seven independently controlled joints that allow for superior reachability in the three-dimensional workspace. "This robot has one redundant joint that can move without impacting the end-effector," says Cui.
