Memristor-based Hybrid Analog-Digital Cerebellum (small brain) for Mobile Robotics
【Abstract】
Algorithms for mobile robotic systems are generally implemented on purely digital computing platforms. As complementary metal-oxide-semiconductor (CMOS) scaling approaches the end of the road, the improvement of the throughput of digital processors and computing power efficiency is nearing its end. This issue not only affects the power requirements of large data centers but also limits the performance of mobile robotic systems with perception and actuation. Developing alternative computational platforms may lead to more energy-efficient and responsive mobile robotics. Inspired by how human and animal brains work, we report a hybrid analog-digital computing platform enabled by memristors on mobile robots. The “cerebellums” (sensor fusion + motion control) of mobile robotic systems are implemented in memristor-based analog circuits, and the rest of the system is implemented in digital circuits. Such a platform can perform computation in the analog domain and thus removes the speed and energy efficiency bottleneck. The robot using the hybrid analog-digital platform demonstrated dramatic enhancement of speed and energy efficiency over the traditional digital platform.
移動機器人系統的算法通常在純數字計算平臺上實現。隨著互補金屬氧化物半導體(CMOS)縮放技術逐漸走向極限,數字處理器吞吐量和計算能效的提升也已接近終點。這一問題不僅影響大型數據中心的功耗需求,還限制了具備感知與驅動功能的移動機器人系統的性能。開發替代計算平臺有望打造出更節能、響應更迅速的移動機器人技術。受人類及動物大腦工作方式的啟發,我們提出了一種在移動機器人上實現的、基于憶阻器的混合模數計算平臺。該平臺中,移動機器人系統的 “小腦”(傳感器融合 + 運動控制)通過基于憶阻器的模擬電路實現,系統其余部分則通過數字電路實現。此類平臺可在模擬域進行計算,從而突破速度與能效方面的瓶頸。實驗表明,采用該混合模數平臺的機器人,其速度和能效較傳統數字平臺實現了顯著提升。
