WebRobotics and Perception Group WebJul 26, 2024 · In contrast, the rough IMU preintegration and INS mechanization without compensating for the Earth rotation yields notable accuracy degradation. When the GNSS-outage time is 60 seconds, the degradation can be 200% for the industrial-grade MEMS module and more than 10% for the consumer-grade MEMS chip.

WebApr 7, 2024 · Achieving collaborative tasks in multi-robot teams requires knowledge of the relative poses of a robot's neighbours. Ultra-wideband (UWB) systems are becoming increasingly popular as a means of inter-robot ranging and communication. A major constraint associated with UWB is that only one pair of UWB transceivers can range at a …
WebMar 26, 2024 · Abstract. Point cloud registration is the basis of real-time environment perception for robots using 3D LiDAR and is also the key to robust simultaneous localization and mapping (SLAM) for robots.
