为了提高仿人双足机器人行走的稳定性及自主性,提出一种基于帧描述及位姿变换的双足步行机器人新型步态生成方法,该方法将一个行走周期细分为14帧,根据机器人的实际结构尺寸并利用几何约束进行步态规划及规划合成。然后根据ZMP(zero moment point)理论及位姿矩阵算法,对所得到的数学模型以及行走过程中的稳定性、智能性等进行了仿真研究。在此基础上完成了基于嵌入式系统的双足机器人系统平台,最后在平台上的实验及仿真结果验证了所提出规划方法的有效性。
A hierarchical-processed frame construction of artificial emotion model for intelligent system is proposed in the paper according to the basic conclusion of emotional psychology. The general method of emotion processing, which considers only one single layer, has been changed in the presented construction. An artificial emotional development model is put forward based on reinforcement learning mechanism of neural network. The new model takes the emotion itself as reinforcement signal and describes its different influences on action learning efficiency corresponding to different individualities. In the end, simulation result based on child playmate robot is discussed and the effectiveness of the model is verified.
