The Calico assistive robot developed by researchers at the University of Maryland can be worn on the user's clothes, where it runs along a track to perform various tasks. The 18-gram robot can localize itself and map a path with sensors that perceive magnetic neodymium markers embedded in the wearer's apparel. Calico can bear a 20-gram payload and travel between 15 millimeters (0.59 inches) and 227 millimeters (8.93 inches) per second, powered by a battery that holds more than eight hours' charge when idle and 30 minutes' charge when moving. The device can show users its progress on tasks by transforming their arm into a physical progress bar, moving further up the limb as they reach daily goals. .. '
