I have also made a post asking what PID is, I am very curious as to what they are and how they work. I am a first-year coder for my team, using V5’s C++. Could I have some info and examples? Would help a lot, would help me understand things, and could significantly improve my code (same with the PI…

Odometry is a way of tracking your robot’s position on the field accurately. It uses “dead wheels” that are on the ground and are not powered by a motor, and shaft encoders to track the distance those wheels move. All of the math is to convert from the movement of the three tracking wheels to a x an…

[image] w30is: IMU is motion profiling No, IMU stands for inertial measurement unit: [image] Inertial Sensor The Inertial Sensor is a combination of a 3-axis (X,Y, and Z) accelerometer and a 3-axis gyroscope. The accelerometer measures linear acceleration of the robot (including g…

Do you just want copy and pasted odometry code?

No, I want an easier way to understand it.

Yeah, I don’t understand trigonometry much. You explained it well here, but how would I code it? (For testing purposes)

In C++, you’ll want to be able to convert between degrees and radians and vice versa. These two functions are reasonable for that purpose: float to_rad(float angle_deg){ return(angle_deg/(180.0/M_PI)); } float to_deg(float angle_rad){ return(angle_rad*(180.0/M_PI)); } You’ll need the sin() an…

The best reference for coding it is going to be the BLRS post . It’s too complex to go into detail on how to implement it on the forum, but if you use the formulas on there you should be able to be successful. If that proves to be too difficult, try to learn trigonometry using youtube so you can act…

I mean trig is sorta a core component of how it works. Maybe this video going through everything slowly will help [Odometry Part 1 - Educational Resources] At some point it comes down to either learning the trig necessary to follow it or waiting until you know the trig.

Brushing off the whole trigonometry thing, I don’t understand a single thing going on in this code block. Is this V5 C++ (I do not have access to PRO and I’m really not sure how a lot of functions work, that’s another thing I have to learn)

This meme post I made a while ago is also relevant.
