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.

尽管Kramer于1975年发明的运动补偿器已经为研究昆虫行走定向机制提供了便利，但在我国，除了一个原型模型外，还没有使用过这种装置。在研制新型运动补偿器项目的规划中，对该装置的控制系统进行了全面的审查，并将其更新为数值控制系统。视频跟踪器跟踪移动昆虫的图像，每隔1/60秒向个人计算机报告物体的X、y坐标，然后计算机处理坐标后将目标位置报告给电机控制板。电路板根据数值数据驱动一对数字控制的交流伺服电机，每个电机轴线上的轮子驱动一个塑料球体。由轮子和万向轴承支撑的球体旋转，使得昆虫在球体上的每次位置替换都是负反馈的。该方案采用现代数字设备，如报告视频跟踪器、高性能CPU的个人电脑、智能电机控制板和全数字控制的交流伺服电机来实现。通过对仪器的组织、独特的机械设计和优化的驱动软件，实现了一种反应平稳、快速的高性能仪器。为了便于实际使用，采用面向GUI的语言编写了一个数据分析软件。通过对软件的完善和包括取样器在内的气流系统的构建，建立了行走昆虫行为修饰剂的筛选系统。
