摘要:

针对轮椅在跨越楼梯、台阶、沟壑等障碍时不便的问题,结合腿式机器人,文中提出了一种新式双足载人机器人的行走机构设计方案。对机器人的行走机构进行了结构设计,其控制简单,仅具有两个自由度。同时为了得到使人体感觉最舒适的乘坐高度,对机器人大腿结构的运动曲线进行三次求导得到加加速度,并通过对加加速度的绝对值分析,确定最优高度。同时,利用Matlab对结果进行仿真,验证了该机器人机构的运动平稳性。经多次试验数据分析,软件评定结果和数学计算理论值基本一致,误差≤1%。

Abstract:

For the problem of wheelchair inconvenience when crossing stairs,steps,ravines and other obstacles,combining with legged robots,this paper proposes the structural design of a new manned biped robot.Just with two degrees of freedom,its control is very simple.In order to get the most comfortable ride height of the human body,take the third derivative of the movement curve of the thigh to get the jerk.Then the optimum height is determined through analysis of the absolute value of the jerk.The simulation results are carried out to verify the motion stability of the robot mechanism by using Matlab.Through multiple test data analysis,the results of the evaluation of the software are consistent with the theoretical values of the mathematical calculation and error rate is less than 1%.

Key words: robot;degree of freedom;height optimization;jerk
