MNN -- Brian Zenowich will sometimes spend his workdays doing a little arm-in-arm dancing. His dance partners manage to stay in step, duplicating his every move almost flawlessly. The “twist” here isn’t the type of dance he’s doing. It’s the fact that Zenowich isn’t dancing with humans. He’s actually a robotics engineer for Barrett Technologies in Cambridge, Mass., where the company makes robotic arms and hands.
