로보트는 현재 그 이용이 다양하고 또 새로운 개발에 따라 점차 그 용도가 광범위함으로 용어의 뜻도 여러가지로 해석되고 있다. 단순반복작업이나 작업환경이 위험한 상황에서 시작된 로보트의 이용은 이제 모든 산업분야에서 또 나아가서는 모든 생활영역에서 그 활용가능성을 한번쯤 검토하게 될 정도로 인간의 현재 작업능력을 쫓아오고 있는 실정이다. 프로그램이 가능한 다기능 머뉴푸레이터라는 정의로 부터 생체의 운동부의 기능에 유사한 유연한 동작기능을 갖는 것이라고 정의되고 있는 다양성있는 로보트를 기계공학의 입장에서 살펴보기 위하여 우선 기계공업의 특성과 문제점을 서술하고 그 합리화 방안의 하나인 산업용로보트의 현황과 기계공학과의 관계를 알아보고자 한다.

In this paper, we propose software algorithms which provide acceleration/deceleration characteristics essential to high dynamic performance at the transient states where industrial robots or CNC machine tools start and stop. Software acceleration/deceleration methods are derived from the mathematical analyses of typical hardware systems controlling acceleration/deceleration. These methods make servo motors, which drive axes of motion, start and stop smoothly without vibration in the repeated tools. The path error, which is one of the most significant factors in the performance evaluation of industrial robots or CNC machine tools, is analyzed for linear, exponential, and parabolic acceleration/deceleration algorithms in case of circular interpolation. The analyses show that path error consists of the distance between the required path and generated one through acceleration/deceleration, and that between the generated one through acceleration/deceleration algorithm and the actual one of the end effector of the industrial robot or tool of the CNC equipment.

This paper presents a design of the PWM digital servo controller and a real-time trajectory planning algorithm and a trajectory tracking algorithm for industrial robot. To be specific, a decentralized control system with hierarchical structure for industrial robot, related hardware and software, and monitor program for convinence of user are implemented. Actually, it was recognized by experiments that continuous path control on the R4 plane was possible using the above servo controller and control algorithms.

Wire harness assembly is one of the most labor intensive processes in manufa- tuing, but the process has not been fully automated yet. In this paper a variety of concepts for flexible automated assembly system are suggested to design a robot- based wire harness assembly cell. All concepts are featuring an automatic, fedkng of wires, terminating routing, inserting and bundling. Based upon possible assembly methods and procedures, six alternative systems are proposed and, finally, evaluated10 from the view point of system performance such as flexibility, reliability assembly time and equipment cost.
