A robotic cart is entertaining patients, staff, and visitors at Children’s Hospital of Wisconsin, after a recent “fashion makeover” made the machine that transports medical supplies and equipment look like a railroad car, the Milwaukee Journal Sentinel reports. The cart—called TUG—now features a conductor who “speaks” using the voice of actor Don LaFontaine. Children’s has been using the cart since October 2007; there are about 100 in use at hospitals across the country. The robot makes about 20 trips a day to transport equipment and supplies such as specialty dressing, oxygen monitors, and feeding pumps throughout the hospital, enabling staff to focus on moving patients more quickly. TUG uses assigned elevators, stops when it senses a person or nursing cart, and parallel parks in a hallway after completing a transport, saying “pardon my caboose” while backing up. According to the hospital’s patient care manager, the extra hand has helped improve attention paid to patients, adding that “anytime you have a chance to…keep the people in touch with the patients, it’s a good thing” (Newson, Journal Sentinel, 3/30/08).
