I’m having trouble with drifting, especially after the robot hits the loader. What sensors are you using to correct your position and reduce the drift?
I don’t have a lot of experience with sensors. However, from what I have seen between different teams and robots, ping sensors are used to help correct drift in general. There may also be a few other strategies when it comes to this. If you need a more in depth explanation of how that works, someone else may be able to help you with that. I sadly can’t really help with that though.
What’s a ping sensor ? Do you mean an ultrasonic sensor ? or distance sensor ?
Very sorry. Yes, I mean a distance sensor. I do way too other robotics projects, so I get things mixed up sometimes.
What do you mean by “drifting”? Are you referring to variation in how much the robot moves?
if I’m being honest, I’m not a huge fan of sensors, if I were you I would adjust the velocity of your code for the side of the wheels that have the drifting to make them faster/slower at the times when it most commonly drifts.
Please don’t tell people not to use sensors. They can be frustrating at times, but they are your best friend. Besides, the motors a feed-back controller (which uses sensors) to supply the correct velocity to the robot.
@1810, I’d reccomend you research odometry. Here is a great rescource for it.
Interesting. Humans tend to really need their senses in order to walk straight and not fall down. I am a huge fan of sensors. 
this is peoboly the most respectful way anyone has ever called me wrong before, good job you’ve convinced me
