How to build a drivetrain for odom

VEX V5 General Discussion General Forum

Next year I am planning on using ‘simple’ odom code for ‘turn and move straight’ commands because it is a bit simpler. I have learned about tracking wheels, rotation sensors and gyro sensors, etc. I am curious how I should go about building the drivetrain with those sensors or wheels and which ones even. I couldn’t find much information online so I thought I would ask on the forum.
(btw I was planning on either 360 on 3.25 or 450 on 2.75 if that makes a difference.)
thank you.

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.
