受蜣螂启发,设计出能适应不同地形和重量的多任务机器人控制算法。
Nature's All-in-One: Multitasking Robots Inspired by Dung Beetles
- 基于蜣螂行为构建模块化神经控制系统,整合步态生成与定向控制。
- 机器人在平坦与不平地形上成功搬运2.0至4.6公斤的软硬球体。
- 适用于需同时行走与搬运的仿生机器人研发,也助力动物运动机制研究。
蜣螂能协调六条腿同时滚动不同重量的粪球,并在多种地形上稳定移动。然而,其在不同条件下如何实现行走与滚球的多任务协调机制尚不明确。本研究通过观察蜣螂滚球行为,提出一种基于神经网络的模块化运动-操作控制方法。该系统包含中央模式发生器(CPG)、模式形成网络(PFN)和机器人定向控制(ROC)等模块,可驱动仿蜣螂机器人ALPHA在平坦与不平地形上完成自适应稳健的多任务运动-操作(行走与滚球),并应对2.0公斤与4.6公斤的球体及软硬材质差异。该控制机制为复杂感知-运动协调的多任务机器人提供了指导原则,同时深化了对动物多任务运动-操作行为的生物学理解。
原文摘要 · Abstract (English)
Dung beetles impressively coordinate their six legs simultaneously to effectively roll large dung balls. They are also capable of rolling dung balls varying in the weight on different terrains. The mechanisms underlying how their motor commands are adapted to walk and simultaneously roll balls (multitasking behavior) under different conditions remain unknown. Therefore, this study unravels the mechanisms of how dung beetles roll dung balls and adapt their leg movements to stably roll balls over different terrains for multitasking robots. We synthesize a modular neural-based loco-manipulation control inspired by and based on ethological observations of the ball-rolling behavior of dung beetles. The proposed neural-based control contains various neural modules, including a central pattern generator (CPG) module, a pattern formation network (PFN) module, and a robot orientation control (ROC) module. The integrated neural control mechanisms can successfully control a dung beetle-like robot (ALPHA) with biomechanical feet to perform adaptive robust (multitasking) loco-manipulation (walking and ball-rolling) on various terrains (flat and uneven). It can also deal with different ball weights (2.0 and 4.6 kg) and ball types (soft and rigid). The control mechanisms can serve as guiding principles for solving complex sensory-motor coordination for multitasking robots. Furthermore, this study contributes to biological research by enhancing our scientific understanding of sensory-motor coordination for complex adaptive (multitasking) loco-manipulation behavior in animals.
