이 글에서는 Multi-Tasking Real Time O.S인 VxWorks를 기본으로 하여 다중센서 융합(Multi-Sensor Fusion) 능력을 갖는 다중 로봇 협조제어 시스템의 구현에 대하여 살펴보았다. 본 제어 시스템은 두대 로봇의 제어에 필요한 장애물 회피, 조건 동작(Conditional Motion) 혹은 동시동작(Concurrent Motion)과 외부 디바이스와의 동기 Motion(Conveyor Tracking)을 수행할 수 있게 구현하였고, 몇몇 작업을 통해 우수성을 입증하였다. 앞으로 본 연구와 관련한 추후 과제로는 1) 자유도가 6관절형인 수직다관절 매니퓰레이터를 위한 충돌회피 알고리즘의 개발, 2) Two Arm Robot의 상대 위치를 위한 Auto-Calibration 시스템의 개발, 3) CAD Based Trajectory 생성 등이 있다.

This paper presents a new motion control for singularity avoidance in 6 DOF articulated robot manipulators, based on a speed limiting algorithm for joint positions and velocities. For a given task, the robot is controlled so that the joints move with acceptable velocities and positions within the reachable range of each joint by considering the velocity limit. The proposed method was verified using MATLAB-based simulations.

Recently industrial robots together with positioners are often used to enhance the system performance for arc welding. In this paper, a redundancy control method is proposed to the robot-positioner system with seven degrees of freedom, where one kinematic modelling technique is employed. Also, manipulability in the given cutting plane of the workspace. An algorithm maximizing the manipulability is applied to the robot and the positioner and the simulation results are shown for the task following a linear path.
