In recent years, parallel mechanisms have been widely introduced to haptic devices for advantageous benefits such as a high rigidity, a high output force, a high accuracy and a high backdrivability by its multi-legged structure and fixed actuators on the base. On the other hand, multi-DOF haptic devices including rotational motions are getting important in resent years as haptic applications have grown more diverse as typified by a surgical training system. However, realizing a multi-DOF haptic device within a wide range of rotational working area by using parallel mechanism is a challenging work. In this research, a 6 DOF (3 translations, 2 rotations and 1 passive rotation) parallel mechanism D-8 is presented to overcome this challenge.

Very interesting parallel mechanism. Quite redundant though for only five DOFs. Do you have further information about this haptic device?
