Hi, I'm trying to reproduce your results on my own to make sure that I really understand your paper Contact-Aided Invariant Extended Kalman Filtering for Robot State Estimation. When I...

Hi, thanks for making this code available. I am trying to use it with a pre determined map of ceiling mounted apriltag markers. (corner positions known). Would you be able...

Hi, I'm trying to reproduce your results on my own to make sure that I really understand your paper `Contact-Aided Invariant Extended Kalman Filtering for Robot State Estimation*`. When I...

hello,When I run simulink, I meet the following problems. Simulink cannot propagate the variable-size mode from the 'Output Port 1' of 'RIEKF_test/Landmark Spoofer' to the 'Input Port 1' of 'RIEKF_test/Orientation...

Hello, I want to implement ZUPT (zero velocity updates). I first thought it would be a piece of cake but I came to the realisation that I have to master...

Just a few improvements to the readme. Neat repository :) Thank you for making it available.

filter.setState() fails when compiled with MUTEX option

Hi, thanks a lot for this code. I am working on a multisensor state estimator for quadruped robots, and I would like to use your inEKF as a benchmark. Still,...

![Image](https://github.com/user-attachments/assets/018c9936-8c8f-4c64-b677-a256da68e59f) Sorry to bother you. Right now I am using this your project to estimate my biped robot. But I found there are many errors of my estimated orientation and...
