To enable impact-awareness in the model-based motion generation paradigms of under-actuated robots, we need the frictional impact dynamics model to preview the impact-induced state jumps either for planning or control, see the recent example by the organizer Wang et al. , the impulsive manipulation example presented by our invited speaker Jia et al. .
The workshop presentation by Jia Yan-bin will bring us the latest 3D impact dynamics model and its application for impulsive manipulation.
