Could you build this?
No This project involves academic-level robotics SLAM research, specifically modifying state estimation and sensor fusion filters (Kalman/factor graph) within C++ LiDAR-inertial odometry algorithms.
What it would actually take: The codebase requires C++, ROS/ROS2, GTSAM, and Eigen to modify FAST-LIO2 (iterated error-state Kalman filter) and LIO-SAM (factor graph optimization). The core challenge is the mathematical derivation and implementation of sensor ablations for IMU accelerometer bias and manifold gravity vector estimation during high-dynamic motion. Deep expertise in robotics state estimation, Lie group theory (SO(3)/SE(3)), and sensor fusion is strictly required.
