inekf-ros

This repository contains a ROS wrapper for the C++ inekf library located at https://github.com/RossHartley/invariant-ekf

This filter can be used to estimate a robot's 3D pose and velocity using an IMU motion model for propagation. The following measurements are currently supported:

• Prior landmark position measurements (localization)
• Estaimted landmark position measurements (SLAM)
• Kinematic and contact measurements
