대부분의 산업용 로봇은 한 팔을 가지고 있어서 그 응용 범위에 있어서 많은 제한을 가지고 있다. 몇몇 특수한 산업용 로봇들이 다중 팔을 가지고 있지만, 일반적으로 각각의 팔이 개별 작업을 수행하는 수준에서 사용되고 있다. 현재 한국기계연구원에서는 이러한 이유로 산업용 양팔로봇의 개발이 진행되고 있으며 이들의 1차적인 적용 목표는 양팔의 협조 작업을 가능하게 함으로써, 양팔작업이 필요하여 아직 자동화되지 못한 자동차 부품 생산라인에 적용하는 것이다. 본 논문에서는 현재 개발이 진행 중인 자동차 부품의 정밀조립용 양팔 로봇에 관해 소개하고자 한다.

In this paper, important design parameters for parallel kinematic robots are defined, paying special attention to machining errors which may cause kinematic errors at the end effector of a robot. The kinematic effects caused by each design parameter, as well as their upper/lower limits, are analyzed here. To do so, we have developed a novel software program to compute kinematic errors by considering its defined design parameters. With this program, roboticists designing parallel kinematic robots can understand the important design parameters for which upper/lower allowances have to be strictly controlled in the design process. This tactic can be used for the design of high-speed, parallel kinematic robots to reduce the design/manufacturing costs and increase kinematic precision.

These days, the interests on the high speed handling robots are increasing because it is important to get down the unit cost of production to get the price competitiveness. The parallel kinematic mechanism is more suitable to implement the high speed robot system as well known. The moving parts of the high speed parallel robot have to be designed for light weight. But the vibration motion is induced by the light weight links because they drive in high acceleration and deceleration. In this reason, the structural analysis of the high speed parallel kinematic robot is very important in the design process. In this paper, the study on the structural analysis of a high speed parallel robot has been done and the research results will be introduced.

Many types of robot systems are used in the mass production line of thin film solar cells and flat panel displays. There are some issues such as the deflection and the vibration of the end-effector because robots handle large and heavy substrates at high speed. Heavy payload and high speed cause much vibration because the end-effector (fork) is made of carbon fiber reinforced polymer because of its light weightiness and sufficient stiffness. This study performs a dynamic simulation of an 8.5G solar cell substrate handling robot, including rigid and flexible bodies and a vibration controller. The fifth polynomial trajectory and the zero vibration derivative input shaping algorithm are applied. The vibration reduction is also proved in the experiments.

The demand for industrial robots has spread across several markets, ranging from the automobile market to the electric and electronic markets, including various IT products. Consequently, the demand for assembly process automation using robots is gradually increasing. Control technology for assembly processes using robots can be classified into two categories. The first method involves force control-based robot control, wherein the robot is actively directed for controlling assembly reaction forces. In the second method, assembly implementation is performed by attaching a passive compliance mechanism to the robot. However, in both methods, implementation of the assembly process through a commercial industrial robot can be difficult. To address this issue, we developed a gripper that can implement the assembly process through a commercial industrial robots which are operated in position-control based robot control. Furthermore, the obtained results are summarized in this paper.
