![]() Unlike human beings, robots are tireless, and their "hands" never shake. There are good reasons for engineers to develop medical robots for use in healthcare. Essentially each person has the ability to give them instructions to perform a task.Would you trust your life to a robotic surgeon? How about your mental health? While some may be uncomfortable with the idea of a robot performing their surgery or comforting them in times of stress, it is becoming increasingly commonplace in the world of healthcare, where interest in (and funding for) medical robots within the field of biomedical engineering is rising. There is no active management, no one sitting at a keyboard. “They are kind of free-roaming, things coming out of the storeroom automatically dispatched. A maintenance person on a ladder changing a lightbulb would stop the AGV, according to Sandhu.Ī chip in the concrete must be repaired as soon as possible so as not to damage the AGVs, Jewell said. One problem with their use is remembering to leave the path free of obstruction. They have a life expectancy of about 10 years, but Jewell believes that a well-serviced vehicle can last longer. When not in service, the robots automatically go to a recharging station, he said. The radio frequency identification-controlled AGVs receive orders, from those with access, via Wi-Fi. The AGVs run on a grid of magnets, with no central control system, according to Jewell. Human employees pick up the items for delivery to patient rooms and other areas.įollow Healthcare Finance on Twitter and LinkedIn. The AGVs pick up containers of supplies and food from a central storeroom and adjacent kitchen prep area and bring them to hubs and depots. The tunnels already existed, but were expanded and the AGV service line added at a cost of $10 to $12 million. Trucks continue to move mail and other back-of-the-house supplies to buildings located farther out, he said, but 85 percent of supplies for patient needs are transported by AGV. Cleveland Clinic’s large campus consists of 44 buildings on 168 acres. ![]() The tunnels connect the hospitals 15 core buildings, according to Jewell. They move 70,000 items daily, up to half-a-mile through a vast underground tunnel system. The robots look like what they have often been called: pallets on wheels. Unlike the colorful “Tugs” at Boston Children’s Hospital – train-like robots that carry cardboard conductor hippos and make a hooting sound as they deliver food to patient rooms – Cleveland Clinic’s AGVs rarely see the light of day. “We wanted supplies closer to when we needed them.” “As we began to grow, we realized we didn’t want a lot of inventory,” she said. “The thing that made it work out that way was, all of those user departments were using the same asset.”įive operational departments count on the AGVs to deliver meals, linens, nursing supplies, FedEx packages, sterile items, oxygen and gases, among other items. “It was roughly over two years on the pay-back,” she said. Plus, hiring people to push the 800 to 1,000 pounds carried by each AGV was “not necessarily the kind of job we wanted to create for people,” Sandhu said. That’s about $45,000 to $50,000 per person per year, for upwards of $5 million, recurring year after year, Sandhu said. They determined the number was a minimum 120 employees, at an average payroll of $14 to $15 an hour, plus benefits. The 81 Automatic Guided Vehicles, or AGVs, cost roughly $100,000 each and have a total $300,000 annual repair and maintenance bill, according to Sandhu and Jeff Jewell, director of warehouse operations at the health system.Ĭleveland Clinic did a rough study of the number of people the hospital would have had to employ had it not invested in the AGVs, Sandhu said. ![]() ![]() The investment paid off in two years, she said. In fact, robots may even play the part of patients for teaching purposes, like at Kaiser Permanente’s Garfield Innovation Center in Oakland, Calif., where they are simulating childbirth.Īt least 1,000 supply-delivery robots are estimated to be in use in hospitals nationwide, and their numbers are expected to grow as hospitals face cost and staffing pressures.Ĭleveland Clinic, the large nonprofit academic medical center, invested in 81 worker bee robots when it expanded in 2008, according to supply chain executive director Simrit Sandhu. Robots also charm patients and visitors at Boston Children’s Hospital and zap harmful bacteria in Sarasota, Pittsburgh and elsewhere.
