Odom Questions

I am going to use a vertical tracking wheel and I’m wondering if I should use a horizontal one too if I already use an inertial sensor?

Thanks

It is by no means necessary (both myself and our sister team just had a vertical one), but if you have the room, I think that you might want to consider having both.

Especially on this game, which doesn’t require your bot to be able to mount anything, it might be helpful, but it is absolutely not necessary.

First of all, what is a verticle tracking wheel and what is a horizontal sheel and what are you trying to accomplish

One vertical + one horizontal + inertial sensor is the golden standard.

Any less will diminish tracking quality drastically.

You’d be surprised how much horizontal drift your robot gets, so while the vertical tracking wheel does a lot of the heavy lifting, the horizontal wheel is still very important. The last time I couldn’t fit a horizontal wheel I had distance sensors to figure out how to reset my drift.

Ooh, how did you rig that system with the distance sensors?

No distance sensors required!

Instead, I would use odometry pods such as below. :slight_smile:

Vertical is for tracking robot movement forward and horizontal is for tracking robot movement when it goes side to side. The goal is for your robot to know where it is on the field precisely(motors are inaccurate and don’t account for drift), so you can have a much smoother auton.
