Abstract
To further exploit the efficiency and robustness of a synergy-driven robotic hand, we present a novel myoelectric impedance controller. This chapter extends the impedance control scheme and hand synergy reference models, previously presented in Chap. 7, and presents a novel teleimpedance controller for the Pisa/IIT SoftHand. In addition, different haptic interfaces are developed to provide the user with some information about the grasping forces and texture.

Notes
- 1.
In this chapter, if not stated explicitly, all the variables and equations are described on the motor side (including interaction torque). Therefore, a gearbox ratio of \(N=84\) must be taken into account for the presentation of the variables after the gearbox.
- 2.
Here we assume that the cuff’s tendon stiffness is very high and the damping effect is negligible due to the slow variations of the observed interaction torques.
- 3.
To allow adequate spacing of the motors in the vibrotactile cuff, only digits 1–4, thumb to ring finger, were used to provide texture feedback.
- 4.
Usually the intercept of the fit model is indicated by \(\beta _0\).
- 5.
