Applied Resources is a manufacturer of The Raptor, the first commercially available, FDA-approved “Smart” Assistive Robot. The Phybotics Division of Applied Resources Corp. introduced the Raptor Wheelchair Robot System in the year 2000. The Raptor received approval from the U.S. Food & Drug Administration in December 1999, and made history in June of 2000 as the first sale of an FDA-Approved wheelchair robot in the United States. The Raptor is also sold in the Netherlands.
The Raptor provides assistance for individuals with severe disabilities who use powered wheelchairs. The robotic arm’s elbow contains a right angle gearbox from Torque Transmission, which offers dual shaft output from an extended shaft input.
The company was seeking an alternative to the heavy, expensive metal gearboxes available on the market and contacted Torque Transmission for help. “Torque Transmission engineers fitted our off-the-shelf RAB-1, Right Angle Miter Gear Drive with special cut gear to give it more torque to meet the customer’s requirement,“ explained John Rampe, President of Torque Transmission. “The result was a low cost, very light weight, yet durable drive,” he concluded.
“The Torque Transmission gearbox was selected for it’s small envelope, light weight and high torque strength,” noted Craig Wunderly, Chief Engineer for Applied Resources. “We subjected the right angle drives to rigorous testing and the drives successfully passed all of our tests,” he concluded.
