Video

Sorry we do not share the robot design. But if you are so eager to rebuild it, why not try and rebuild it based on the video and thumbnail? Maybe you can even improve some parts of the robot :)

Thanks brother, but I’m not going to use it on the VRO, we don’t have that level yet for another task, I wanted to redo the mechanism, the grip will break on the side@@Flawil_Beavers

@@Flawil_Beavers how did you use rgb ?

@@taha.79 Just by using the RGB function in ROBOTC Btw: Happy new year

@@Flawil_Beavers Happy new year :) What programming language do you use? And do you have some useful tricks or blocks in Mindstorms?

@@taha.79 We used ROBOTC because we don't like graphical programming. Regarding EV3-G: we have very little experience. E.g. we never created a custom block. So we can't give you any tips about it. Consider joining the Discord for more questions. It's a bit easier to answer there

Just acceleration and deceleration with syncing of the wheels

Looks like a simple PID (maybe just PD) loop to me

First we used Python because it was easy to learn. Then we moved on to ROBOTC as this language is compiled and therefore much faster than Python.

​@@Flawil_BeaversVery good, thank you very much for answering me. Greetings.

No, we did not have that problem, because we use our own function to determine the colours. It is based on the RGB values.

@@Flawil_Beavers Thank you so much. You are very kind to respond to me.

Thanks, yes we do use odometry sometimes. E.g. In the second run of the second day we used odometry to place the two coloured container. But for this run we calculated everything on paper.

Sorry, we do not share our whole program. But if you have specific questions about how our program works, feel free to ask on the Discord server.

We just use the RGB values to follow the line instead of the reflected light intensity. For more info please ask on the Discord Server.

I need the same help

Ask again on the discord server. We will provide the 3D model there.
