<Research and Activity>
Accurate and robust control of robots in highly dynamic tasks is arguably one of the hardest open problems in robotics. The incapability of robots to interact with their environment in a safe and reliable manner is what still refrain them from becoming ubiquitous in our society. The main challenge is due to the non-smooth nature of such dynamic tasks as they often involve impacts between parts of the robot and its environment. Examples are legged locomotion, non–prehensile manipulation or aerial robot landing. A suitable prototype of those kind of system is represented by the ubiquitous ball-dribbling robot. The main challenges offered by this system are: under-actuation, dynamic decoupling between the robot and the ball, impacting interactions and emergence of chaos in the uncontrolled dynamics.
In our research we firstly consistently modelled the system and analysed its properties. Then, a novel energy–based controller is derived from physical intuitions on the system. This controller enhances the classic energy shaping with iterative learning control, allowing the robot to rhythmically bounce the ball at a desired height. In order to prove the effectiveness and robustness of the controller we performed simulation experiments.

<Comments and Future Plan>
It is our pleasure to be selected as Young Author Award winners. We will proceed our research to receive Best Paper Award in the next conference.
