PHILADELPHIA — Need a hand lifting something? A robotic device invented by University of Pennsylvania engineering students can help its wearer carry an additional 40 pounds.
Titan Arm looks and sounds like part of a superhero’s costume. But its creators say it’s designed for ordinary people — those who need either physical rehabilitation or a little extra muscle for their job.
In technical terms, the apparatus is an untethered, upper-body exoskeleton; to the layman, it’s essentially a battery-powered arm brace attached to a backpack. Either way, Titan Arm’s cost-efficient design has won the team accolades and at least $75,000 in prize money.
‘‘They built something that people can relate to,’’ said Robert Carpick, chairman of Penn’s mechanical engineering department. Full story for BostonGlobe.com subscribers.
