Its primarily the fact that people have been figuring out better mechanisms to do wallstakes with hood than were available previously, such as some recent developements in using the Lady Brown mechanism on hoods, where it was much harder previously.
hood redirect is what im talking about. Ex machnia and 99% have both developed mechs that make hood redirect possible and alot more efficent in my opinion than hook redirect. there are also some people who ahve developed lady brown for hood.

hood ladybrown:
I agree with Hook because it seems to score more consistently. A Hood if tuned and treated it call be profitable but it may require an overhang to push the ring down.
Having already been a hook user, and just now reading this thread, I think that both have their place. At the competition I attended this past friday, the top bots were a mix of very successful hood and hook intakes. The hook intakes were much simpler, and any team there that was worth their salt was using hook. The higher level teams, such as some of the Greenville teams, were using hood intakes to great effect, and they were much faster than the hook intakes. Our hook intake (which definitely wasnât perfect but it worked) was decent for being run on two 18:1 motors, but there were a few instances where the chain slipped off of a tensioner sprocket and wouldnât score a ring. It was also very prone to catching on the 5th or 6th ring on a stake, and we had to be very accurate and overly precise with what direction we were driving when trying to score on a stake, otherwise the ring would miss. Iâm not saying either is better, but I think my team will be switching to hood, as weâve had too many problems with hook and hood seems to be better with redundancy and reliability.
Thanks for coming to my TED talk.
I agree! At the greenville comp I went to there were successful Hook and hood bots the finals consisted of 4148Z who had a really good hood that that helped my team 1239E who was a hook bot win the tournament. The other alliance consisted of a hook ladybrown bot and a hood bot both of which were really good so it mostly came down to the driver. What I took away from the tournament is that it doesnât really matter what type of robot you have, it mostly is up to driver strategy and skill.
Precisely. Both can be effective, it really just depends on whoâs building it and whoâs driving it.

Me when no fish mech:
This bot should get a FUN interview.
I forgot about fish mech
What is a fish mech?
the way I think of it is like an arm that acts as a massive hook. Here is a video were Luke (one of the best vex youtubers rn imo) breaks down the differences. Basically a large arm with a few standoffs or bits of poly to hold the ring and act as a massive hook.
I currently have a hood intake that is on an arm that can lift up to reach the wall stakes but making plans on either switching to a lady brown hook intake or staying with a hood and trying to make a lady brown work with it. The only reason I donât consider fish mech is because I believe that lady brown has more potential to be able to score 2 rings at a time where fish mech is limited to 1 by design.
Iâve noticed on some hook designs that they have flex wheels on the top shaft where the rings get dunked onto the goal. Can someone explain what they do and if they make the intake work more efficiently.
I think the purpose of the flex wheels is to increase grip. When the conveyor ends, the hooks will spin downwards. Without grip from a similar mechanism, sometimes the ring could fly out, so flex wheels are added to make the trajectory of the ring more reliable.

They are to control the angle the ring flips at. If they are closer to the sprocket then the front of the ring flips faster I believe, and if they are farther then the back flips faster.
