摘要
介绍了一种电磁微马达驱动的可重构微型移动机器人.设计了一种灵活的被动式万向连接器.多个基本的微机器人模块可手工连接在一起形成可自动脱离的被动式拖车,通过动力和无线通信接力方法来扩大它们整体的探测范围.以降低被动式拖车的轨迹跟踪误差为目标,通过运动学分析揭示了其轨迹跟踪误差与万向连接器的前后连接杆长度之间的关系,并给出了相应的运动学方程以及控制方法.实验结果证明了上述方法的可行性.
A reconfigurable mobile microrobot actuated by electromagnetic micromotors is presented.A flexible passive universal connector is designed.Multiple basic microrobots can be connected with each other manually to form a passive trailer with automatic disconnecting function,and their whole surveillance range can be enlarged by adopting the method of power and wireless communication relays.To reduce the tracking error of the passive trailer,relationship between the errors and the lengths of the front and back link rods of the passive connector is revealed by kinematics analysis,and the related kinematic equation and control method are derived.The experimental results demonstrate the feasibility of the concepts.
