Journal ArticleDOI
Navigation Assistance for the Visually Impaired Using RGB-D Sensor With Range Expansion
TL;DR: The proposed system detects and classifies the main structural elements of the scene providing the user with obstacle-free paths in order to navigate safely across unknown scenarios, resulting in the robust expansion of the range-based floor segmentation.
Journal ArticleDOI
Homography-Based Control Scheme for Mobile Robots With Nonholonomic and Field-of-View Constraints
Gonzalo López-Nicolás,Nicholas Gans,Sourabh Bhattacharya,Carlos Sagues,J. J. Guerrero,Seth Hutchinson +5 more
TL;DR: A visual servo controller that effects optimal paths for a nonholonomic differential drive robot with field-of-view constraints imposed by the vision system is presented and controllability and stability analysis are provided.
Journal ArticleDOI
A Sliding-Mode-Control Law for Mobile Robots Based on Epipolar Visual Servoing From Three Views
TL;DR: A new control law is proposed that achieves convergence to the target with no auxiliary images and without changing to any approach other than epipolar-based control, thus allowing the robot to move directly toward the target as well as avoiding the need of a precise camera calibration.
Journal ArticleDOI
Switching visual control based on epipoles for mobile robots
TL;DR: A visual control approach consisting in a switching control scheme based on the epipolar geometry that facilitates a classical teach-by-showing approach where a reference image is used to control the robot to the desired pose (position and orientation).
Journal ArticleDOI
Formation Control of Mobile Robots Using Multiple Aerial Cameras
TL;DR: A new vision-based control method to drive a set of robots moving on the ground plane to a desired formation using multiple camera-equipped unmanned aerial vehicles (UAVs) as control units, relying on a homography computed for each UAV-mounted camera.
