RoadCompass: following rural roads with vision + ladar using vanishing point tracking
Autonomous Robots - Tập 25 - Trang 205-229 - 2008
We present a vision- and ladar-based approach to autonomous driving on rural and desert roads that has been tested extensively in a closed-loop system. The vision component uses Gabor wavelet filters for texture analysis to find ruts and tracks from which the road vanishing point can be inferred via Hough-style voting, yielding a direction estimate for steering control. The ladar component project...... hiện toàn bộ
Probabilistic lane estimation for autonomous driving using basis curves

Stair Climber Smart Mobile Robot (MSRox)
Autonomous Robots - Tập 20 - Trang 3-14 - 2006
MSRox is a wheeled mobile robot with two actuated degrees of freedom which enables it to have smooth motion on flat surfaces. It has the capability of climbing stairs and traversing obstacles, and adaptability toward uphill, downhill and slope surfaces. MSRox with 82 cm in length, 54 cm in width and 29 cm in height has been designed to climb stairs of 10 cm in height and 15 cm in width; neverthele...... hiện toàn bộ
Energy-optimal trajectory planning for car-like robots
Autonomous Robots - Tập 37 - Trang 279-300 - 2014
When a battery-powered robot needs to operate for a long period of time, optimizing its energy consumption becomes critical. Driving motors are a major source of power consumption for mobile robots. In this paper, we study the problem of finding optimal paths and velocity profiles for car-like robots so as to minimize the energy consumed during motion. We start with an established model for energy...... hiện toàn bộ
Self-assembly strategies in a group of autonomous mobile robots
Autonomous Robots - Tập 28 - Trang 439-455 - 2010
Robots are said to be capable of self-assembly when they can autonomously form physical connections with each other. By examining different ways in which a system can use self-assembly (i.e., different strategies), we demonstrate and quantify the performance costs and benefits of (i) acting as a physically larger self-assembled entity, (ii) letting the system choose when and if to self-assemble, (...... hiện toàn bộ
Maintaining strong mutual visibility of an evader moving over the reduced visibility graph
Autonomous Robots - Tập 40 - Trang 395-423 - 2015
In this paper, we address the problem of determining whether a mobile robot, called the pursuer, is able to maintain strong mutual visibility (a visibility notion between regions over a convex partition of the environment) of an antagonist agent, called the evader. We frame the problem as a non cooperative game. We consider the case in which the pursuer and the evader move at bounded speed, travel...... hiện toàn bộ
Detection of doors using a genetic visual fuzzy system for mobile robots
Autonomous Robots - Tập 21 - Trang 123-141 - 2006
Doors are common objects in indoor environments and their detection can be used in robotic tasks such as map-building, navigation and positioning. This work presents a new approach to door-detection in indoor environments using computer vision. Doors are found in gray-level images by detecting the borders of their architraves. A variation of the Hough Transform is used in order to extract the segm...... hiện toàn bộ
Angle-based homing from a reference image set using the 1D trifocal tensor
Autonomous Robots - Tập 34 - Trang 73-91 - 2013
This paper presents a visual homing method for a robot moving on the ground plane. The approach employs a set of omnidirectional images acquired previously at different locations (including the goal position) in the environment, and the current image taken by the robot. We present as contribution a method to obtain the relative angles between all these locations, using the computation of the 1D tr...... hiện toàn bộ
