Bimanual manipulation is essential for robots to reach human level manipulation dexterity. The involvement of the second robot arm is believed to greatly increase the dexterity and flexibility of robot manipulation and therefore to open new directions for both research and real world applications. But it is still a problem to identify the challenges in general and in modules which have slowed down or blocked this kind of novelty benefiting human beings? It is clear that we cannot focus on solving purely issues at the components level. We need a holistic, interdisciplinary perspective of robotic bimanual manipulation. Therefore it is important for roboticists from both academic and industrial community to join efforts together to review, re-investigate, reshape and pave the way to advance the field of research. To navigate our discussion,  we prepared the following question to be answered in the workshop.
