“Our long-term goal is to make robots that have mobility, dexterity, perception and intelligence comparable to humans and animals, or perhaps exceeding them; this robot is a step along the way.”—Marc Raibert, Boston Dynamics
在双足行走方面,目前国际上大多数采用的是ZMP方法(Zero Moment Point,即当机器人足与地面完全接触无欠驱动现象时,水平方向的合力矩为零的点),本田的ASIMO也采用了该方法。ZMP依据的思想就是使机器人足与地面保持静止,在此条件下,只要在支撑多边形内,机器人就是瞬时平衡的,如果每个周期都是瞬时平衡的,则机器人就能达到长期平衡。
