One-on-one fitness instruction plays a significant role in motivating seniors to stay in shape. A talking robot dubbed Bandit encourages a person seated in front of it to engage in customized exercises, ranging from easy to challenging. Although still in the research and testing stages, the robot is capable of leading a person through a series of arm movements or imitating arm movements modeled by the person. It’s one of six socially assistive robots, or SARs, being developed by the Interaction Lab of theViterbi School of Engineering at the University of Southern California.
