论文摘要
在这项工作中,提出了一个多合一的神经形态控制器系统,具有减少机器人臂的延迟和功耗。生物肌肉运动包括通过来自运动神经元的尖峰指示信号拉伸和收缩纤维,这些信号又与中央模式发生器神经结构相关。此外,生物系统能够快速有效地对不同的刺激做出反应,这是基于在神经过程中编码信息的方式。与人类创建的编码系统相反,神经元使用神经元和尖峰来处理信息并基于连续学习过程做出加权决策。事件驱动的Scorbot平台(ED-Scorbot)由6个自由度(DOF)机器人组组成,其控制器的控制器实现了尖峰成比例综合的衍生算法,以此方式模仿了先前评论的生物学系统。在本文中,我们向ED-Scorbot平台提供了基础架构升级,取代了控制器硬件,该硬件由两个Spartan现场可编程门阵列(FPGAS)和一台带有边缘设备的排骨计算机组成,带有边缘设备,Xilinx Zynx Zynq-7000 Soc(chip on Chip)降低了响应时间,并降低了响应时间,并降低了整体上的响应时间。
In this work, an all-in-one neuromorphic controller system with reduced latency and power consumption for a robotic arm is presented. Biological muscle movement consists of stretching and shrinking fibres via spike-commanded signals that come from motor neurons, which in turn are connected to a central pattern generator neural structure. In addition, biological systems are able to respond to diverse stimuli rather fast and efficiently, and this is based on the way information is coded within neural processes. As opposed to human-created encoding systems, neural ones use neurons and spikes to process the information and make weighted decisions based on a continuous learning process. The Event-Driven Scorbot platform (ED-Scorbot) consists of a 6 Degrees of Freedom (DoF) robotic arm whose controller implements a Spiking Proportional-Integrative- Derivative algorithm, mimicking in this way the previously commented biological systems. In this paper, we present an infrastructure upgrade to the ED-Scorbot platform, replacing the controller hardware, which was comprised of two Spartan Field Programmable Gate Arrays (FPGAs) and a barebone computer, with an edge device, the Xilinx Zynq-7000 SoC (System on Chip) which reduces the response time, power consumption and overall complexity.
