2941 Robot Reveal (Post-World Cup)

2941 and 2941B recently competed in the Robot World Cup held at the Cloud on Auckland’s waterfront.

We came in to the tournament as the third seed from the driver skills challenge, with a score of 32 for both robots. After division play, we were in 3rd place (2nd in our division), and we also managed to get the top of Pool C. In the quarter finals we faced the formidable Lynfield/Free Range Alliance (2915a and 2921a), and a combination of their superior robots and some Vexnet dropouts led to us being knocked out, gaining a top eight spot.

Now that World Cup is over, we decided we are going to make some big changes to our robots, which means we are now able to do a reveal on our old ones (2941 and 2941b were almost identical) 2941b is still identical to our robots that competed in the World Cup, and is still intact (unlike 2941a) so we thought we should take the time to post this on the forums.

A feature of 2941b that 2941a did not have was a functional Vexnet key… grrrr…

Thats all I can think to post for now, if anyone has any questions or wants any more photos/videos of anything specific I would be more than happy to post them.

Thanks for reading.**

Great robot! Sounds like you had a very successful start to the season. I’m surprised at the use of 3-wire motors on the lift, have you had any problems? Also, how does your intake flip out at the beginning of the match? It seems to be folded in at a very sharp angle.

The reason we use 3-wire motors on the lift is because we don’t have enough money to buy more 2-wires :cool:. And yes, We did have problems. They overheat if used for too long, however, this is only an issue during practice, as the games are not long enough to make them overheat.

The intake folds down at the start because we used preloads. This means that if the intake is rolled in reverse, the intakes roll off the preloads, and are pushed down. Yes, you are correct, the intakes could not fold down without having preloads in.

I like that you have the ability to keep movement while picking up game objects.
That is VERY effective.

I also like how fast the game objects are pulled into your collection mechanism.
I think that is the fastest I have seen so far.

Looks like you have had a GREAT start to this years VEX Game: Gateway!
Keep up the good work!
