After surgery, a robot may be at your side In quest for efficiency, savings, hospital is testing at-home mechanical monitors

When Erin Tally took Aidan, her 2-year-old son, home from Children’s Hospital Boston on the day after his urinary surgery, she brought along a new friend: a 4-foot-6, 17-pound, two-wheeled robot to help care for her recovering child. Overthe course of  two weeks and five video consultations, the robot, made by Vgo Communications Inc., of Nashua, eliminated the need for Tally to drive Aidan into Boston every three days for post-surgical checkups.

Vgo Communications worked with Verizon Wireless’s Innovation Program center in Waltham, where the telecom company helps incubate new technologies, to embed Verizon’s cellular communications technology into the robots. Through its connection to the cellular network, a Vgo does not need to rely on Internet broadband connections.

“Eventually, I see a whole fleet of these robots being sent home with patients,’’ said Dr. Hiep T. Nguyen, an associate professor at Harvard Medical School and director of Children’s Hospital’s Robotic Surgery Research and Training Center. “With this technology, we’re going to be able to replace hospital monitoring with home-based monitoring.’’
