This paper presents a robotic application for in situ repair of the seal surfaces of a large hydropower spherical valve. The repair involves laser scanning, machining, welding and polishing using the portable track-based Scompi robot. To perform the machining, the robot uses a tool guide mechanism that locates accurately the machining tool and holds it against the work surface despite large disturbance...
In this paper we present the approach for autonomous planetary exploration developed at the Canadian Space Agency. The goal of this work is to autonomously navigate to remote locations, well beyond the sensing horizon of the rover, with minimal interaction with a human operator. We employ LIDAR range sensors due to their accuracy, long range and robustness in the harsh lighting conditions of space...
In this paper we present the work done at the Canadian Space Agency on the problem of planetary exploration. One of the main goals is the over-the-horizon navigation of a mobile robot on a Mars like environment. A key component is the ability to plan a path using maps of different resolutions and also to refine/replan when more data becomes available. Our algorithms on path planning and path segmentation...
The success of NASA's Mars exploration rovers has demonstrated the important benefits that mobility adds to planetary exploration. Very soon, mission requirements will impose that planetary exploration rovers drive over-the-horizon in a single command cycle. This require an evolution of the methods and technologies currently used. This paper presents experimental validation of our over-the-horizon...
The success of NASA's Mars Exploration Rovers has demonstrated the important benefits that mobility adds to planetary exploration. Very soon, mission requirements will impose that planetary exploration rovers drive autonomously in unknown terrain. This will require an evolution of the methods and technologies currently used. This paper presents our approach to 3D terrain reconstruction from large...
