从信息论的观点出发，探索利用信息熵的概念来研究机器人的位姿精度理论。建立了机器人位姿信息传输模型，提出基于熵概念的机器人位姿精度新评价指标体系，论文还对它有望弥补解决目前机器人位姿精度理论中研究不足的可能性进行分析探讨。 From the point of view of information theory, the concept of information entropy is explored to study the attitude and attitude accuracy of robots. The pose information transfer model of robot is established and a new evaluation index system of pose accuracy is proposed based on the concept of entropy. The paper also analyzes and probes into the possibility of making up for the lack of research in robot pose accuracy theory.
