摘要
针对弹跳仿生机器人存在的主要问题,结合婴猴体型小且具有平稳暴发弹跳的特点,提出了一种仿婴猴单腿弹跳机器人,对其主要结构和控制系统进行了设计。通过分析婴猴的腿部结构,基于Stephenson六杆机构原理,设计了一种仿婴猴机器人腿部的平面八连杆机构,并对其轨迹进行优化,获得了具有最佳弹跳能力的杆长参数;对机器人弹跳的3个方向进行控制调整,利用双闭环反馈控制系统实现了机器人在起跳、腾空、落地时姿态的稳定;最后,建立了机器人的实物验证模型,整个机械装置质量为395.5 g,整体高度为250 mm。实验结果表明,该仿生单腿机器人可实现连续稳定的跳跃,最高弹跳速度可达20 m/s,弹跳高度为100 mm时的响应时间为0.1 s。
Aiming at the main problems existing in the jumping robot,combined with the galago senegalensis monkey's characteristics of small sizes,stable and explosive jumping,a kind of galago senegalensis monkey single leg jumping robot is proposed in this study,and its main structure and control system are designed.Based on the principle of the Stephenson's six-bar linkage,a planar eight-bar linkage for the leg of simulating galago senegalensis monkey robot is designed,and its trajectory is optimized to obtain the bar length parameters with the best jumping ability.The three directions of the robot's jumping are controlled and adjusted,and the double closed-loop feedback control system is used to ensure the stability of the robot's attitude when taking off,soaring in the air,and landing on the ground.Finally,the physical verification model of the robot is established.The total weight is only 395.5 g,and the overall height is 250 mm.The experimental results show that the simulating single leg robot can achieve continuous and stable jumping,the highest jumping speed can reach 20 m/s,and the response time at a jumping height of 100 mm is 0.1 s.
