Wire-driven mechanism and highly efficient propulsion in water.
自然生物的杰出表现往往令人们叹为观止。正因为如此,在机器人研究中对自然界动植物的模仿从未间断。本文受动物肌肉骨骼系统(尤其是蛇的脊柱以及章鱼手臂的肌肉分布)的启发,设计了一种新型的仿生拉线机构。该机构由柔性骨架以及成对拉线组成。柔性骨架提供支撑,拉线模拟肌肉将驱动器的运动和力传递给骨架,并控制骨架运动。从骨架结构分,拉线机构可分为蛇形拉线机构以及连续型拉线机构;从骨架分段来看,拉线机构可分为单段式拉线机构以及多段式拉线机构,其中每段由一或两对拉线控制。拉线机构的主要性能特征包括:大柔性,高度欠驱动,杠杆效应,以及远程传力。机构的柔性使得它可以产生很大的弯曲变形;欠驱动设计极大地减少了驱动器的数...
