This paper presents the preliminary tests of an adapted user interface that performs an hybrid fuzzy-Deformable Virtual Zone(DVZ) pilot. The proposed concept uses a safely guidance algorithm for the powered wheelchair user and a laser range sensor to avoid collision. An adapted user interface is developed so that the accessibility and the mobility of disable or aged people especially those suffering...
The paper presents a hardware architecture for implementing a mobile robot localization approach through encoders' measurements and absolute localization using camera tracking images. This technique has been developed and implemented for the motion of the robot from an initial position towards another desired position, taking into account the tradeoff between complexity (reducing computation time)...
This paper describes teleoperation systems for remote control of robot and the use of 3D virtual reality. It presents the adopted architecture and describes the experimental implementation through simulation results for mobile robot Khepera.
This paper presents a fuzzy-logic controller and navigation algorithm for guiding an omnidirectional robot. Based on introduced start and reference points, with respect to the inverse kinematic model, the fuzzy logic controller is used to steer the robot to follow the planned poses so as to reach the target point. Our contribution consist on extending a behavioral approach basing on Deformable Virtual...
This paper presents an implementation of robot localization algorithm using FPGA technology. The adopted localization method uses webcam tracking images. This technique has been developed and implemented for the motion of the robot from an initial position towards another desired position. Firstly, we have validated our approach on PC platform using C language and OpenCV library. Secondly, for the...
This paper addresses the control problem of unicycle mobile robot evolving in unknown environments using reactive behaviours. The deformable Virtual Zone (DVZ) principle is used to resolve this problem through defining a safety zone around the vehicle. This approach presents fast control laws that react depending on the presence of an obstacle in the safety zone. Experimental tests are carried out...
