Should my team use pid or ODOm to program our robot

hi im Ranchsauce2456 and our team wants to program our robot for autonomous. I read somewhere taht pid and ODOm are good for doing this. Which ones better? … is a question I’ve heard many times from newer teams. So let’s have a crack at answering this question. (Spoiler: It’s neither!) To first answer our question, let’s first take a look at what Odometry and PID actually are. Odomometry (Shortened to Odom colloqually) Odometry is some sort of system to keep track of a robot’s position on the …

How to mechanically press odom wheels into the ground?

Here is a poor MS Paint drawing of how it may work [image] Sorry, but I don’t have CAD skills

What is the best way to mount odomentry wheel?

@9935E, if you would like to see VEX Worlds winning robot’s tracking wheels mech and odometry algorithm that goes with it, then it is your lucky day: But, if you will insist that 5225A’s design is not accurate enough for your not yet built robot…

What is the best way to mount odomentry wheel?

yeah screw joint works out pretty well with 250rpm drive on 4” wheels [image] it never leaves the ground and have us some accurate programming results. U see a shaft joint because we ran out of space, but we made it with screw joints afterwards and there is nearly zero slop when built correctly

Usually, this is achieved in 1 of 2 ways:

1. Odom pods. This involves 3 pods or 2 pods and an inertial sensor to determine robot location. Usually the most accurate.
2. Inertial sensor and motor encoders. Simpler, but may be slightly inaccurate sometimes due to wheel slippage/slop.
