In this paper,we introduce some former researches ,present the architecture of the IWB,describe its main functions ,and discuss key techniques in the resarch of IWB.展开更多
关节化虚拟人在执行维修作业过程中,不可避免的需要用手臂去操控各种操作对象,为此提出了一种基于 Petri 网的关节化虚拟人手臂动作模型。模型首先利用逆向运动学方法计算出在目标位姿下的关节链上各关节的角度,进而利用关节插值方法,...关节化虚拟人在执行维修作业过程中,不可避免的需要用手臂去操控各种操作对象,为此提出了一种基于 Petri 网的关节化虚拟人手臂动作模型。模型首先利用逆向运动学方法计算出在目标位姿下的关节链上各关节的角度,进而利用关节插值方法,以仿真循环迭代的方式实现对手臂关节链上各个关节的运动控制。仿真和实验结果验证了所提方法的可行性与实用性。展开更多
