The article proposes a feedback control system for path following in presence of obstacles that is an extension of previous work and is made of two components: (i) a sensor-based, real-time model that generates and periodically updates the path on-line in order to avoid both known and unforeseen obstacles, and (ii) a feedback-control model that is capable of driving a unicycle vehicle along the collision...
This paper is devoted to design and implement an intelligent scaled car-like mobile robot that possesses the capability of autonomous driving in an extra-road environment and fully autonomous parking on standard parking lots. The final goal is to design a robotized system that is able to process in real-time large amounts of sensor based data, to choose a collision free drivable trajectory thru detected...
This paper shows the capability of our environmental testbed to validate novel cooperative control algorithms that rely on measurements from the environment. Through the design of our mounting plates, the testbed can accommodate multiple environmental sensors as well as different configurations of robot accessories. Also, our environmental sensor suite provides the ability to integrate a variety of...
The article proposes a feedback control system for real-time navigation and obstacle avoidance that is made of two components: (i) a sensor-based, real-time model that generates and periodically updates the path on-line in order to avoid both known and unforeseen obstacles, and (ii) a feedback-control model that is capable of driving a unicycle vehicle along the collision free path. The system has...
Classical motion planners and most of navigation routines discard dynamics of the system and therefore fail in some special conditions. If a robot is moving towards an obstacle with a high acceleration and speed, collision is inevitable because the obstacles are taken into account only either once they are in range, or a physical collision is reported by detection routines. In this paper, we have...
The paper describes the design of the fuzzy control system for an autonomous robot car which operates in unknown, unpredictable, and dynamic environment. The fuzzy control system must provide the fusing of data from multiple sensors and must ensure navigation of the autonomous robot car. Both - an obstacle avoidance control strategy and a target tracking control strategy - are used for the control...
Active flippers for tracked vehicles are very useful to improve traversability on uneven terrain. However it is widely known that control of flippers also increases the work-load for operators, particularly where the vehicle and the operator are far apart. To reduce the work-load, we aim to realize a sensor-based autonomous controller of flippers to enable a ldquosemi-autonomous operationrdquo of...
