91-03/EXOS.inf EXOS, Inc. 8 Blanchard Rd. Burlington, MA 01803. Pricewise, they are in the U.S. $15k range. One of their products is the Dexterous Hand Master. This is an exoskeleton for the hand (a position sensor to locate the hand in 3-space would have to be attached - they are willing to attach one for you if you don't have your own engineers for such). The exoskeleton is roughly 11 ounces. Straps anchor the exoskeleton to each finger joint and the wrist. Finger bending and side to side motions are measured, in all 20 distinct angles. These angles are measured by a ``Hall Effect sensor'' (don't know what that is) which is accurate to half a degree. Each channel can be sampled up to 100 times per second (RS422 or RS232 connectors available - RS422 gives maximum output rates). There is supporting software for PC AT, Macintosh, and VME systems. The sensor technology was ``originally developed at Arthur D. Little as an outgrowth of research carried on for NASA.'' Sales brochure targets remote operation of robotic hands, control of musical performances, and artificial computer environments. The other product that looks interesting is called GripMaster. It comes as an IBM AT compatible critter. One angle sensor is attached to the wrist and back of hand and a force sensor is attached to the middle joint of each finger (at least in the sales brochure). Force sensor can measure in range from 0 to 30 pounds with sensitivity of 0.25 pounds. Again, measured at a rate of 100 samples per channel per second. Apparently this was developed with looking for potential sources of hand/wrist injuries, analyzing comfort in design of tools, workstations, and products, and training workers.
