University of Zurich AI Lab Uses Baumer Sensors to Monitor Movement of Roboy

Southington, CT (PRWEB) May 08, 2013

Motion experts at The Baumer Group began working closely with scholars from the Artificial Intelligence Laboratory (AI Lab) at the University of Zurich In June of 2012 to design and create the first humanoid robot that moves, acts and responds like a human being. Nine months later, Roboy was born and introduced to the world at Robots on Tour in Zurich, Switzerland, on March 8, 2013.

Standing at just over 4 feet tall, Roboy resembles a young boy. His physique approximates the body of an 8-year-old child. His movements are smooth and flowing, like human movement. His programming allows him to have touch sensitivity and face recognition.

Roboys movements are patterned on those of humans. Classic robots have servomotors installed directly in their joints, a design that makes them move in a stiff, jerky manner. Roboy, however, features tendon-controlled drive technology where joints are manipulated using plastic tendons that join the bones of the artificial skeleton together. Electric motors stretch and contract each tendon, imitating the smooth, controlled muscle movement working in the human body.

To simulate the human locomotor system, Roboy’s project team of scientists and industry experts designed the robots internal motion system using more than 100 analog sensors from Baumer. These high-precision, extremely compact sensors provide position feedback, determining and communicating the exact location of the robots movable body parts. With this information, Roboys computer brain can direct and control the activity of the electric motors that stimulate muscle movement.

Baumers sophisticated, 6 mm tall capacitive sensors make it possible to shake hands with Roboy. Because these sensors are designed to detect fluid levels, they can easily sense the water content in a human hand. When a person stands near Roboy and reaches out a hand in greeting, the capacitive sensor located in Roboys palm detects the water content in the human hand and sends a message back to the robots computer brain that a handshake is imminent. The brain then alerts Roboy to respond appropriately by clasping his human partner’s hand.

“A humanoid robot is certainly not an ordinary application for our sensors, says Sascha Schmid, product market manager, sensor solutions at Baumer. The Roboy project is, however, an excellent example of the numerous and special sensor solutions that Baumer can offer.
