摘 要
在操作步行机器人时，只有让所有的油缸协调动作，才能使之安全、稳定的行走。本文所研究的这个大型液力驱动步行机器人ALDURO并没有外部力量的供给。因此，在机器人平台上的液压装置及其柴油引擎的尺寸大小都将被它们自身的重量所限制。当各个油缸以高速运动时，液压力的供给就将不足，从而导致机器人的脚步及其整个平台的移动轨迹都将变成不可预知的。当此ALDURO在接近其稳定边界的状态运作就将导致它的不安定甚至是整个系统的瓦解，下面将讨论的解决方案是用于发现这种油缸时位错误并由此在需要的时候降速。
ABSTRACT
When operating walking machines, only a coordinated movement of all cylinders and/or motors can lead to safe, stable walking. The large hydraulically driven walking machine ALDURO, which is investigated in this paper, has no external power supply, and therefore the size of the on-board hydraulic power pack and its diesel engine is limited by its weight. When moving several cylinders with high speed, the hydraulic supply can become insufficient and the resulting trajectories of feet and platform can become unpredictable. When the ALDURO is near its stability limit such behaviour can lead to instability and toppling of the system. The proposed solution under discussion here is to observe the position errors and time derivatives for the cylinders and based on this reduce the speed when necessary.
