If you do holecount, do it badly.
We have a hood now but i dont have a picture with it attached
Aye, but what about the rest?
Ill have to take a picture of it later to show you but we dont have any anti-static mat for the the ball yet and we are ordering more bearing flats.
Basically the only problem we have is that the intakes arent far enough into the goal.
Can one or all of you try and edit the photo of my robot and add intakes that you think sould fit best for my team so i can use those and create my own because it might work better than the intakes i have now
This was before adding everything such as the intake from the previous photo
Oh god no. You’re not supposed to use anti static mat on your robot! That’s for field tiles!!! Use vex adhesive foam, or traction fabric.

We like to help but we’re not going to do everything for you. There’s an amount of personal responsibility here.

the build quality on that whole robot in general is a bit lacking. I don’t think that you could get a good level of speed/consistency with your current build.
But of course we all start somewhere, and this is a perfect opportunity for your to improve your build quality! watching reveal videos and studying the builds of other robots is a great way to learn important build techniques.
general tips I can offer:
- use bearings whenever a shaft goes through a metal hole
- make sure you have enough bracing between structural components, like the sides of your drive. from what I can see, you only have a single c channel holding your entire drive together. Instead you should have many many braces to ensure rigidity. take a look at this topic about drive construction: Designing a Quality Drive - #7 by 224x
- make sure your holes are aligned. vex holes are larger than the screws, which means if you don’t align it perfectly and tighten it way down, there will be some slop and wiggle between holes which leads to jankiness in the construction.
- try to avoid constructing with plates, they’re heavy, flimsy, and provide almost no structural integrity. c channels are way better for rigid components, and polycarbonate is almost always better for flat flexible uses that don’t require strength.
- I can’t exactly tell from the picture, but it kind of looks like you’re using zipties to hold some parts together. never ever do this. just no.
as a good rule of thumb, you want all parts of your robot that are not supposed to move independently to act as a single rigid component.
I can tell just by looking at your robot that the parts of the frame can easily bend and flex independently of each other. The way to mitigate this is to use strong pieces, brace them well, and mount them to each other in the strongest ways you can.
if you find yourself struggling with improving your build quality, there’s no shame in building a clawbot/crunchbot, they suck competitively, but they will definitely help you improve your basic building knowledge.

Sorry anti slip mat

If you don’t want your robot falling apart then use nylon nuts on every screw. P.S you will need a wrench of some sort if you use these. Nylon Nuts
You can also buy locktite and apply it to your screw for a stronger connection.

But do you? You literally are asking for help because you don’t know how to build a robot.

Yes i do its just that i was asking for tips on how to build it
Let’s not get too salty. The point of the forum is to help people understand their mistakes and give them suggestions when deemed necessary, not do it for them. The definition of tips is a small-sided suggestion. Like a tip would be to use bearing flats or never have two moving pieces of metal in contact. @NicolBolas people with more knowledge in a subject should strive to help people in need when possible. @Teel I don’t want to misinterpret your intentions but part of the engineering process and what VEX wants their customers/students to do is to try to figure some things out on their own. I don’t want to speak for VEX considering I don’t work for them but that is the general picture. Receiving help from others is fine but learning to be a bit more independent will also help you a lot.

I know ive been watching videos
The first step to learning is to admit that you don’t know. It will make you more open to understanding and even listening to things that you may already understand.

I completely agree. It’s just a pet peeve of mine when people don’t connect the wires for fairly obvious or minimally creative ideas and ask people to do it for them, especially when they contradict themselves and in their defense. @Teel, I understand that this can be hard, but this forum is a tool to be used when needed, and not a crutch to be leaned on. My best advice is to hole count other good robots from memory badly enough that you make your own “take” on a certain meta design. If you do things from memory more than 5 hours after you’ve seen them, then you’ll end up making your own design that’s your own.

I’m glad you agree. 20
