Abstract
<p>Real-time vision allows the direct steering of a robotic manipulator. In this thesis we use a stereo rig mounted on an industrial robot (ABB IRB-6/2) which gives us information about the end effector position of a second robot (ABB IRB-2000/3). This second robotic manipulator performs the task of tracking a moving object, which in our case is a rolling ball.</p> <p>The first concern of this project is to deal with the different kinds of problems occurring in such a system. After measuring the time-delays in our system we can establish the degree in which they effect it. We can then use these results for the actual control loop. More specifically a Kalman predictor scheme is implemented to produce estimates of coordinates for requested... (More)
