For robotic deployments in planetary worksite environments, map construction and navigation are essential for tasks such as base construction, scientific investigation, and in-situ resource utilization. However, operation in a planetary environment imposes sensing restrictions, as well as challenges due to the terrain. In this thesis, we develop enabling technologies for autonomous mapping and navigation by employing a panning laser rangefinder as our primary sensor on a rover platform. The mapping task is addressed as a three-dimensional Simultaneous Localization and Mapping (3D SLAM) problem. During operation, long-range 360 degree scans are obtained at infrequent stops. These scans are aligned using a combination of sparse features and odometry measurements in a batch alignment framework, resulting in accurate maps of planetary worksite terrain. For navigation, the panning laser rangefinder is configured to perform short, continuous sweeps while the rover is in motion. An appearance-based approach is taken, where laser intensity images are used to compute Visual Odometry (VO) estimates. We overcome the motion distortion issues by formulating the estimation problem in continuous time. This is facilitated by the introduction of Gaussian Process Gauss-Newton (GPGN), a novel algorithm for nonparametric, continuous-time, nonlinear, batch state estimation. Extensive experimental validation is provided for both mapping and navigation components using data gathered at multiple planetary analogue test sites.

El desarrollo de sus habilidades experimentales es parte imprescindible en la formación de un estudiante de ingeniería. Un profesional en ingenie ría debe saber medir, usar correctamente las unidades, observar críticamente un fenómeno, redact ar correctamente un informe, etc. Estas habilidades se adquieren durante el desarrollo de l os cursos de Física. Los cursos de Física, por su carácter experimental, brindan oportunidades únicas para el desarrollo de tales habilidades; por ello es de gran importancia la incorporación de los labo ratorios en los cursos de esta ciencia, pero es igualmente importante que estas se desarrollen de u na manera organizada y con objetivos bien definidos sobre la base de la estructura curricular de los cursos de Física, así como de la experienci a de los profesores encargados de esta actividad. Por esta razón es que consideramos necesaria la presentación de esta guía de experimentos para los cursos de Física, a fin de que los estudiantes desarrollen de una manera organizada y consciente l os diferentes trabajos experimentales y puedan así madurar los conceptos que les serán de gran uti lidad no sólo en sus cursos posteriores de ciencias para la ingeniería, sino también en su act ividad profesional.
