Abstract

According to the work of Jacobs [1], we propose to control standing-up by applying independent controllers of three global variables (length l and orientation ϕ of the vector between ankle and body center of mass (CoM) and the orientation θ of the trunk). Furthermore, we propose to control l by modulating the activation of mono-articular muscles and to control ϕ and θ by modulating the activation of biarticular muscles (see also [1]). This division of tasks between mono-and biarticular muscles was found in postural control in cats [2]. Our simulations indicate that effective and well co-ordinated standing up may be achieved using this concept, allowing for a range of initial postures and arm support forces.
