Hello World, As you can probably tell from my post history, I’m not nearly as active here as I should be. For those of you that don’t know me, my name is Nick Mertin, and I was the head programmer for Team 5225A, The E-Bots PiLons during the 2017-2018, In The Zone season. I have since graduated, bu…

Truly very impressive. Thank you for sharing! 5225 has been a pleasure to watch over the years and has clearly proven to have world-champion worthy controls software :slight_smile: (literally) While the arcs are very interesting, I’m curious as to how necessary they are given the resolution of VEX …

When you average the left and right encoder, you are essentially calculating the chord under the arc that the robot traveled. You don’t actually need to know the length of the arc. This video helps
