Introduction to haptics and haptic technologies

W.S. Harwin, University of Reading - Nov 2015

This material available on the internet from page http://www.reading.ac.uk/~shshawin/LN/ and then follow the Haptic devices link .

Haptic device design guidelines

Parallel mechanisms may be the answer but often a parallel mechanism has a smaller workspace, limiting the realism of the haptic interface.

Lowering inertia with system stacking

System stacking, An intelligent vibrotactile device on a back drivable device on an admittance device!
