The system discussed in this paper is an integrated stand-alone system with the full functional capabilities required of a telerobot system. It is complete with a force-reflecting 6-DOF hand controller, driving a PUMA 560 or 762 robot, with an integrated force-torque sensing wrist sensor and servo-driven parallel jaw gripper. A mix of custom and standard electronics, distributed computers and microprocessors, with embedded and downloadable software, have been integrated into the system, giving rise to a powerful and flexible teleautonomous control system.

This study was carried out to develop an agricultural robot for fruit harvesting. As the first step an experimental manipulator and its control system were constructed. The articulated manipulator driven by DC motors has 3 degrees-of-freedom. The manipulator has a gripper adequate for fruit harvesting and an upper arm which forms a kind of guiding channel so thai harvested fruit can pass through. Point-to-point control of joints are accomplished by a digital control system with a PID controller which consists of optical shaft encoders, power amplifiers using PWM, a microcomputer and a software. The microcomputer also computes the positions of manipulator and sequence of motions. The motion of the manipulator was to slow and rough that it would need further improvement.

본 연구는 로봇착유기 개발을 위한 기초연구로서 유두위치 측정장치와 로봇제어 시스템을 구성하고 그 성능을 분석하고자 수행되었으며 그 결과는 다음과 같다. 1. 유두인식은 스테레오 측량법에 기초한 이미지 장치로 처리했으며 유두인식오차는 (x, y, z) = (0.83, 1.95, 0.81)mm이다. RCS로 좌표값을 변환했을 때 시스템 전체의 오차는 x = 0.9mm, y = 2.0mm, z = 0.9mm였다. 2. 로봇 유두컵 착탈 시스템의 로봇 착탈 성공률은 평균 91.5%로 나타났다. 작업시간은 27.8sec였으며, 이미지 처리를 포함한 전체 작업시간은 86.1sec로 나타났다.
