THE AI ANGLE

Appearing only in the name of the research institute

Researchers built AthenaZero, a two-armed robot with compliant joints and humanlike force properties. The system threw, caught, and hit baseballs in initial tests. This work provides an alternative to stiff factory arms by using low-inertia joints that yield to external forces.
