At present, there are some conception confusions about organization, team and group, and also team formation is still in qualitative analysis phase in multi-robot field.

目前在多机器人领域，对组织、团队和群体概念比较混乱，团队形成的研究大都停留在定性分析阶段。

Meanwhile, it puts forward the conception of Angle adjusting mechanism from the fact that the wheel clearance could lead the changes of phase-angle between two roller.

同时，针对由齿轮间隙引起的两冲辊之间(即凸、凹模之间)相位角的变化，提出设计角度调整机构的理念。

This shift in thinking around the nature of the relationship and the potential value derived from it (that competitive edge) has them engaging earlier in their process, at the conception and architecture design phase of their projects, rather than once they have the specification developed.
