Screening system of behavior modifying chemicals for insects by using a locomotion compensator.

尽管由Kramer于1975年发明的运动补偿器为研究行走昆虫的定位机制提供了各种便利，但除了一个原型之外，我国还没有使用过这样的装置。在这项新的运动补偿器项目的规划中，对装置的控制系统进行了彻底的审查，并将其更新为数字系统。视频跟踪器每隔1/60 S就会追踪运动中的昆虫的图像，并向个人计算机报告物体的X、Y坐标，然后计算机将坐标处理后，将目标位置报告给电机控制板。该电路板根据数值数据驱动一对数字控制的交流伺服电机，每个电机轴上的一个轮子驱动一个塑料球。由轮子和万向轴承支撑的球体被旋转，使得昆虫在球体上的每一次位置替换都被负反馈。该方案是利用现代数字设备实现的，如报告视频跟踪器、高性能CPU的个人计算机、智能电机控制板和全数字控制的交流伺服电机。通过系统的仪器配置、独特的机械设计和优化的驱动软件，实现了一种响应平稳、快速的高性能仪器。为了方便实际使用，用面向图形用户界面的语言编写了数据分析软件。通过完善软件和包括喷样器在内的气流系统，建立了步行昆虫行为改良剂的筛选系统。

Although locomotion compensators, invented by Kramer in 1975, have been facilitating researchers in various study of orientation mechanism of walking insects, no such apparatus has been utilized in our country except for one prototype model. In the planning of this project of making a new locomotion compensator, the control system of the apparatus was thoroughly reviewed and updated into a numerical one. A video-tracker chases the image of a moving insect and reports X-, Y-coordinates of the object to a personal computer every 1/60 s, and then the computer, after processing the coordinates, reports the destination position to a motor-control board. The board drives a pair of digitally controlled AC servo-motors according to the numerical data, and a wheel on the axis of each motor drives a plastic sphere. The sphere, supported by the wheels and a universal bearing, is rotated so as that every positional replacement of the insect on the sphere is negatively fed back. This plan was realized with modern digital equipments as a reporting video tracker, a personal computer with a high performance CPU,an intelligent motor control board and full digitally controlled AC servo-motors. As a result of organized instrumentation, a unique mechanical design and an optimized driving software, a high performance instrument with smooth and quick response was accomplished. A data analysis software was programd in a GUI oriented language for the convenience of practical use. By perfecting the software and an air flow system including sample applicators, the screening system of behavior modifying chemicals for walking insects was established.
