Researchers at the University of Maryland have 3D printed a soft robotic hand that can successfully play Nintendo’s mega-hit Super Mario Bros of the 1980s. Soft robotics involves new types of flexible or inflatable robots that run on water or air. , instead of electricity, according to a release of the college.
The team, led by University of Maryland assistant professor of mechanical engineering Ryan D. Sochol, 3D-printed fully assembled robot parts with integrated fluidic circuits in one go, the key to the Nintendo abilities of this nimble robot bot. player. It is like a fully automated Power Glove but only half of the damned.
The team designed an integrated fluidic circuit, which allows the hand to operate in response to the force of a single control pressure, according to the statement. Using PolyJet 3D Printing, a type of layered printing that stacks many layers of 3D multimaterial, also saved the team time during construction. The investigation was published in Science Advances on July 14.
“Previously, each finger on a soft robotic hand would normally need its own line of control, which can limit portability and usefulness,” study co-author Joshua Hubbard said in the statement. “But by 3D printing the smooth robotic hand with our built-in ‘fluidic transistors’, you can play Nintendo based on a single pressure input.”
While playing, low pressure on the robot’s index finger could make Mario walk and high pressure could make him jump. The team set up a schedule that alternated between off, low, medium, and high pressures, and as a result, the robot’s hand beat the first level of Super Mario Bros. in less than 90 seconds.
But why video games? The time and level structures of the Mario games were a good testing ground for the robot hand. So it’s fun.
