Does anybody have an idea for a hook intake that doesn’t need 1st stage intake? I also want to ask about y’all’s opinion about this intake below and will it work?

you could try something like 1000a used. I think that overall having a 1st stage with flex wheels is probably better but you are free to try whatever you’d like, test things yourself, don’t just copy teams, be unique.

Here’s some competition footage from one of my team’s tournament matches. We are the team on the red alliance with an auton. Our robot does not have an intake which isn’t the most ideal, however it’s very consistent.

What did you use for your hook? And do you need a mogo clamp with that idea?

Most teams choose to cut plastic for their hooks, then put those hooks on standoffs attached to chains
yes you will need a goal clamp. Since object posession is 2 rings, having no mogo clamp will make playing the game much much harder

For our hook we stacked two sleds (I think that’s what they’re called) onto some standoffs. Yes, you would need a mogo clamp for this design but it works just fine with a motorized clamp.
neither of our 2 teams have a 1st stage for our intake, despite the fact that we have 1 hook and 1 hood robot. our other team used a beice of bent polycarbonate as the hook. I don’t know how much tuning it took, but it works well in most situations (although it does occasionally struggle to pick up against walls).
I have to say I was doubtful at first but I’ve done my testing and its actually working very well for our team. I will take back most of what I’ve said before, I still think that flex wheels are more consistent and have some pros but not having them isn’t hurting as much as I had thought. Plus not having them saves a motor (or a lot of messy chain) for whatever you want it for too. We didn’t go the route of pick up like that jhawk/9motor gang video but more like 1000a or 74947k. I have found it just as consistent and fast this way and it saves us a motor. and with 11w we now have a way more unique design that were very proud of, plus our drive train is now 77w 450 on 3.25 with piston wall stakes. It definitely takes some tuning on the pick up though, i also am looking at changing the hooks to be pointer with this style.
Can you take a closer picture of your intake please? I’m trying to see how y’all put it on your drivetrain
Is it ok to have a 100rpm direct mogo clamp that can hold the mobile goal in place but the goal is still on the ground and is being drag around on the field? I’m wondering if this is going to overheat the motor since dragging the mogo on the ground will create friction.
You should be fine, we used a motorized red cartridge clamp and it worked well.
Yeah my team stacked one of those over another and it worked fine. Our team just made a design change to having two standoffs attached to a pillow block bearing with a small standoff jutting out from it.
Here’s an example image,
(sorry for the bad quality)
Can our team build this in 2 hours? We are having a time problem here and our drivetrain is in pieces
Yes, we had pretty much exactly what you described and it worked very well.

Don’t copy the drivetrain. It isn’t legal even if you get permission from him to build it.
May I ask why you choose a chained drive over geared drive? Also why did you guys decide to go with 4 inch wheels instead of 2.75" or 3.25" wheels?
Depends on your build speed, it takes a lot of fine tuning so more than two hours would be ideal. If you are locked in and have a clamp then you could probably speedrun this and get it done in that time frame.

You could build it in two hours but I would take some time for the drivetrain as a bad drivetrain or poorly built one can really impact you so just try to make sure it’s good from the start. Also building time is purely dependent on if you have a plan or not as pieces can not align or spacing is too much etc… Even with a plan it can still be challenging sometimes

Maybe if everyone works very systematically. Have everything planned before you get to practice.
