Degeneracy-Resilient Teach and Repeat for Geometrically Challenging Environments Using FMCW Lidar
Katya M. Papais, Wenda Zhao, Timothy D. Barfoot
Teach and Repeat (T&R) topometric navigation enables robots to autonomously repeat previously traversed paths without relying on GPS, making it well suited for operations in GPS-de…
Ultra-wideband Time Difference of Arrival Indoor Localization: From Sensor Placement to System Evaluation
Wenda Zhao, Abhishek Goudar, Mingliang Tang +1
Wireless indoor localization has attracted significant research interest due to its high accuracy, low cost, lightweight design, and low power consumption. Specifically, ultra-wide…
Range-Visual-Inertial Sensor Fusion for Micro Aerial Vehicle Localization and Navigation
Abhishek Goudar, Wenda Zhao, Angela P. Schoellig
We propose a fixed-lag smoother-based sensor fusion architecture to leverage the complementary benefits of range-based sensors and visual-inertial odometry (VIO) for localization.…
A Remote Sim2real Aerial Competition: Fostering Reproducibility and Solutions' Diversity in Robotics Challenges
Spencer Teetaert, Wenda Zhao, Niu Xinyuan +21
Shared benchmark problems have historically been a fundamental driver of progress for scientific communities. In the context of academic conferences, competitions offer the opportu…
Uncertainty-aware Gaussian Mixture Model for UWB Time Difference of Arrival Localization in Cluttered Environments
Wenda Zhao, Abhishek Goudar, Mingliang Tang +2
Ultra-wideband (UWB) time difference of arrival(TDOA)-based localization has emerged as a low-cost and scalable indoor positioning solution. However, in cluttered environments, the…
UTIL: An Ultra-wideband Time-difference-of-arrival Indoor Localization Dataset
Wenda Zhao, Abhishek Goudar, Xinyuan Qiao +1
Ultra-wideband (UWB) time-difference-of-arrival (TDOA)-based localization has emerged as a promising, low-cost, and scalable indoor localization solution, which is especially suite…
