Controlling and Measuring Impedance in Variable Stiffness Actuators for Robotics

In the talk, I will review some of the background, motivations and state
of the art for the design of variable impedance actuators for robotics.
I will then introduce the problem of controlling these actuators, both
in open loop - i.e. planning, possibly in an optimal way, their motions
and stiffness trajectories - and closed loop. The problem of measuring
stiffness will be hence considered, and several recently introduced
techniques to identify or estimate impedance will be reviewed and
