This invention concerns the design and implementation of a variable steering stiffness for a passive robotic vehicle. In service robotics applications, such as robotic trolleys for elderly, the invention allows to modulate the user perceived authority: when the motion safety decreases, the vehicle authority and its stiffness increases.
