In this paper, a novel exoskeleton for the index
finger is introduced. Such a device is intended to be used for the
rehabilitation of post-stroke patients. The target of the design is
to produce a device with low weight and reduced space
occupation, so that it can be worn without interfering with
everyday use of the hand. The actuation is provided using lowcost lightweight miniature DC motors, and position feedback is
obtained through potentiometers. A working prototype has been
built and tested. A closed-loop position control with friction
compensation has been implemented and experimental results
are presented and discussed.
