CraterGrader: Autonomous Robotic Terrain Manipulation for Lunar Site Preparation and Earthmoving

RSS 2024poster

Establishing lunar infrastructure is paramount to long-term habitation on the Moon. To meet the demand for future lunar infrastructure development, we present CraterGrader, a novel system for autonomous robotic earthmoving tasks within lunar constraints. In contrast to the current approaches to cons…

Belief Space Planning for Reducing Terrain Relative Localization Uncertainty in Noisy Elevation Maps

ICRA 2019poster

Accurate global localization is essential for planetary rovers to reach mission goals and mitigate operational risk. For initial exploration missions, it is inappropriate to deploy GPS or build other infrastructure for navigating. One way of determining global position is to use terrain relative nav…

Programmable Triangulation Light Curtains

ECCV 2018poster

A vehicle on a road or a robot in the field does not need a full-featured 3D depth sensor to detect potential collisions or monitor its blind spot. Instead, it needs to only monitor if any object comes within its near proximity which is an easier task than full depth scanning. We introduce a novel d…

Improving Slip Prediction on Mars Using Thermal Inertia Measurements

RSS 2017poster

Rovers operating on Mars have been delayed, diverted, and trapped by loose granular materials. Vision-based mobility prediction approaches often fail because hazardous sand is difficult to distinguish from safe sand based on surface appearance alone. Unlike surface appearance, the thermal inertia of…
