Mobil robotika

Mobile robotics has been a rapidly expanding area of research in the last two decades. With the recent developments of artificial intelligence the focus of research has shifted towards autonomous vehicles. With a vast area of applications ranging from cleaning robots, robots aiding the elderly of the disabled to driverless cars, this field of research is certain to shape the future of men and machines. The research in our lab focuses on the perception problems arising with mobile robots. Since these robots often operate autonomously, they have to perceive and react to their environment intelligently. We have a remote control car system used for education purposes, aiming to introduce students to the problems of teleoperation and remote sensing. We also have a racing car which we are converting into an autonomous vehicle capable of beating a visual obstacle course.

Visual Obstacle Course for Mobile Robots - Autonomous robots and vehicles are a significant area of research at our lab. Since autonomous decision making requires plenty of classical vision or similar perception tasks, our lab focuses on robot vision mainly. Our lab has a trophy Flux Buggy racing car and several visual sensors, such as a Bumblebee stereo camera and a Kinect sensor, which may be used to build an autonomous mobile robot system.

Traffic Sign Detection for Autonomous Cars - Visual perception of the environment is an essential task for any autonomous vehicle. In the case of everyday traffic recognising traffic signs is a fundamental part of this problem. While there are increasingly precise online databases available for traffic rules, still, combining the data received from these with real time perception is recommended in order to avoid errors caused by inaccuracies, slow updates or loss of connection.

Collision Detection and Avoidance - Perhaps the most important aspect of the science of autonomous vehicles is the detection and avoidance of accidents or other dangerous scenarios. In fact, frontal collision detection and automatic braking systems have been in the market for quite a few years. In many cases, however, braking is not enough to avoid accidents, therefore course adjustment is also needed. This introduces several problems, namely the assessment of safe avoidance paths. In our research we tackle the problem of frontal collision detection and the finding of safe avoidance paths using a forward-facing camera.
