Abstract

A tracked crawler robot using body heat detection and a purpose built analogue tracking circuit is designed in this work. The infrared detection module consists of a single dual element pyroelectric infrared sensor. The drive and steering control system is designed using a single chip 74HCXX Quad 2-input NAND gate as the logic controller and providing constant forward propulsion whilst in real time adjusting to the subject's direction. Automatic tracking of animal or human subjects is the sole purpose of the design. The range has been limited to two meters, with a maximum range of five meters. Modification of the pyroelectric sensor enables detection of both left and right movement. The robots ability to follow human and animal motion has been achieved. Visually observed results show the robot is able to drive, turn and detect human and animal motion and can work reliably. The design is able to be utilized using a microprocessor or as a highly responsive analogue unit making it both adaptive and flexible.
利用热释电传感器和模拟电路的人体跟踪机器人设计
本文设计了一种基于体热检测的履带式履带式机器人和专用的模拟跟踪电路。红外探测模块由单个双元件热释电红外传感器组成。驱动和转向控制系统采用74HCXX四路双输入NAND门作为逻辑控制器,提供恒定的正向推进,同时实时调整主体的方向。自动跟踪动物或人类受试者是该设计的唯一目的。射程被限制在2米,最大射程为5米。对热释电传感器的改进使其能够检测左右运动。实现了机器人跟随人和动物运动的能力。视觉观察结果表明,该机器人具有驱动、转弯、检测人和动物运动的能力,工作可靠。该设计能够使用微处理器或作为一个高响应的模拟单元,使其既自适应又灵活。
