Sensor Configuration Matters: A Systematic Evaluation of Multimodal SLAM on Quadruped Robots
A new research paper evaluates how different sensor configurations impact the performance of Simultaneous Localization and Mapping (SLAM) systems on quadrupedal robots. The study, conducted on an ANYmal D robot using the GrandTour dataset, found that stereo camera setups are more effective than monocular or RGB-D configurations. Global shutter cameras also proved superior to rolling shutter cameras in reducing tracking failures during dynamic movements. Furthermore, the research indicates that standard inertial sensor integration can sometimes degrade the performance of vision-centric SLAM frameworks when subjected to the intense vibrations and rapid rotations characteristic of legged locomotion.
