Since pre-historic times mankind has dreamt of machines that imitate organisms or even surpass humans in their abilities, and time and again ingenious craftsmen B and later engineers B have attempted to actually build such machines. Today's robots are the latest result of an ongoing technical evolution that has progressed over more than 2000 years. Many robots work in factories where they produce...
Robots that never need any calibration of their kinematics, their actuators or their sensors promise great advantages in terms of maintenance cost, robustness and dependability. Here we propose an approach for realizing such robots for calibration-free vision-based object manipulation. The underlying concepts are based on the utilization of laws of projective geometry that always apply, regardless...
Information processing within autonomous robots should follow a biomimetic approach. In contrast to traditional approaches that make intensive use of accurate measurements, numerical models and control theory, the proposed biomimetic approach favors the concepts of perception, situation, skill and behavior - concepts that are used to describe human and animal behavior as well. Sensing should primarily...
A method allowing a mobile robot to measure accurately its distance from external objects is introduced. It requires only a single uncalibrated camera and a dynamic vision system. The method was evaluated in an optical laboratory and also in outdoor experiments. Even in outdoor-experiments with a vehicle moving at a speed of 30 km/h, errors of less than 1% of the true distance were achieved in real...
