Odometry Explained - Robotic Eagles 15173

This is our team's explanation of how odometry works with FTC and how we create and calibrate our robot to make precise movements and know its exact location and heading.
We hope this helps. Feel free to ask any questions or add suggestions in the comments below.
This is part two of a four part series that we are doing to show how we make our autonomous efficient and precise. More videos are coming soon.

This is excellent. I shared your video with my programmers.
Thank you so much for creating these resources for other teams.

Do you implement any methods to detect slippage of the wheels? This would require other sensors such as an IMU. Btw this is super impressive, great work!!!

[@shilpaganesh8323]

For a beginner team who wants to explore odometry, where to start? What are all the components to implement odometry in the autonomous?

[@sk-mi1kb]

How do you put the odometry wheels in the hardware map to use in the robot?

[@spidernh]

Do you think middle schoolers could do this? I'm on a Michigan team and we do FTC in middle school. I think it would be really cool to do odometry and I'm just making sure someone like me could do this before I ask my coaches. We've gotten stuff like OpenCV working and have tried to optimise a lot of things, I'm just not sure if we're smart enough to use odometry.

It is definitely doable. With the time between this season and the next one you will have plenty of time to experiment and get it working. Plus there are plenty of tutorials online and libraries that make the job a lot easier such as Roadrunner.

@@roboticeagles15173 I'm not sure how much time we have though. Usually we don't meet in the summer because FRC always meets in their off season and on a normal year we end in early december so it's not much time

[@roboticeagles15173]

Try building just the robot chassis over the summer or just after your state tournament. It shouldn't take more than a month. Calibration and all can be done at the beginning of the season.

@@roboticeagles15173 Yeah, maybe that could work. And maybe once our team thinks of a design for our robot we can start making an autonomous path while they build something that can be put on the robot.

[@DataLanator]

What do I need to buy to do odometry. I want to make sure I get all the parts

[@lindalian8297]

Where did u guy learn the dead wheel program?

[@yashajeltuhin]

We created our own program. Our refined code is in github as stated in the video

Can i connected with someone.
