摘要
针对机器人在轨构建空间桁架结构的装配序列规划问题,提出一种可同时求解装配单元装配序列与机器人运动的序列规划方法。首先设计了装配机器人并建立了动力学模型;其次,对机器人在整个装配过程中的运动进行了分类并分别给出了规划与控制方法;然后,建立了装配序列规划的评价指标并采用离散粒子群算法求解。最后,以常用空间桁架结构为例,通过仿真校验了所提方法的有效性。
Aiming at the assembly sequence planning of space truss structure constructed by robot on orbit,a method is proposed to solve the assembly unit sequence and robot motion simultaneously.Firstly,the assembly robot is designed and its dynamic model is established.Secondly,robot motions in the whole assembly process are classified and the planning and control methods are given.Then,the evaluation index of assembly sequence planning is established and is optimized through discrete particle swarm optimization.Finally,simulation of a common spatial truss structure assembly is perfound to verify the effectiveness of the proposed method.
