【摘要】 针对大规模晶格式自重构机器人系统整体难以运动的问题,提出了通过局部晶格畸变实现晶格式系统整体运动的方法.给出了一种晶格畸变的规则,并根据此规则设计了一种模块结构,用离散置换群对此模块的重构运动特征进行了分析.利用由6个模块组成的2个晶格进行了畸变硬件实验,验证了这种结构模块组成的晶格可以实现晶格畸变.基于Vortex+OSG的高保真虚拟仿真平台,通过52个模块组成的晶格式机器人系统进行了蛇形运动的计算机仿真,结果证明了局部晶格畸变产生全局运动方法的有效性.更多还原

【Abstract】 For the difficulty of the large-scale lattice self-reconfigurable robot system moving as an ensemble,a novel method to achieve the whole motion through local lattice distortion is proposed.One of lattice distortion rules is given,a module structure is designed according to this rule,and the reconfiguration features of this module are analyzed with discrete substitution groups.Through a physical distortion experiment with 2 lattices consisted of 6 modules,it is validated that the lattice distortion can be achieved by the lattice composed of these modules.Through the high-fidelity virtual simulation platform based on Vortex+OSG,snake-like motion computer simulation of a lattice robot system consisted of 52 modules is conducted,and the results show that the proposed method can yield global motion through local lattice distortion.更多还原
