Abstract :
In this work we show that an Acrobot can be made to behave as a robotic swing. This is achieved by controIling the first joint, provided that a given condition is satisfied. When this condition is not satisfied, the system undergoes through singular points. Even when this happens, we are again able to make the system behave as a swing by controIling the second joint and employing a new energy pumping strategy. This strategy presents important advantages compared to previously proposed strategies, as it is the only one that can start the system from rest and drive it to large heights. Moreover, it is fast and requires very small torques.
