Sensor Exoskeleton Arm-Master for Robot Control 

Exos, Inc. 

Woburn, MA 
 

Development of a sensory feedback exoskeleton arm-master (EAM) that  provides force feedback to the human arm

• Patient pending design of a 5 degree-of-freedom force  feedback device that tracks the motions of, and provides  force feedback to, the shoulder, elbow and forearm
• The EXOS EAM provides feedback on forces due to  contact with objects in a virtual environment without  employing sensory substitution
• Received a US Patent-Number: 5709219

• Technology derived from EAM led to the EXOS Powerstick  (patent pending), a controller providing a sense of touch  for home video games, personal computers and arcades
• Game industry leaders are actively supporting the company 
• EXOS was bought by Microsoft as a direct result of this technology 

• NASA - force feedback enhances realism of object  interaction in virtual or tele- erated environments and can  help in design of task environments and training of crew  members
• Other - robot control arms for tasks in unstructured  environments
