Yes. You should first, add drive motors and attach them to the brain with wires. Then, make all four wheels omni-wheels (if you do make two wheels traction wheels, you have to really know what you are doing and have good reason for it). But for Rise Above, I think it might be valid maybe… This is just my opinion, so feel free to say something else.

Ok thanks! Were actually doing the razor bill with lots of modifications so its helpful to get advice from someone who created the razor bill! Thanks again!

These are some of my tips, no obligation. If you are building a Razorbill-like robot, then I’d highly suggest four omni-wheels. Your drivetrain looks pretty solid though (more than I can say for some bots). Also, I like your battery replacement system, but be careful as an upside down battery is subject to fall out when driving a match, especially over the goals. An additional tip, use 6+ rubber bands (we use 10). Overall an awesome robot so far, and I can’t wait to see how it performs!

Yep im working on the rubber band part right now

I would switch oout you sprockets on the wheels out for the second smallest ones. this will make the rbot much faster. also add a brace on the top sprocket. again like @FRC973 said these are just suggestions but i think it would be very beneficial.

Ok thanks a lot! 20 char
What??!!??!
Does it just go straight up if it’s not being powered? I mean, that’s insane!!!

I could see how that could seem insane, but try it, and you will see what I mean.
Our goal is to put the least amount of force on the motors as possible. It stays pretty much wherever you put it (top, bottom, etc.), so it takes equal force to make it go down and up. This way, you can practice for a long time without heating up your motors.
A motor on the end of a 4-bar is heavy. The longer the 4-bar, the more rubber bands.

Full disclosure, we have built this design.
And with 1x beams instead 2x beams for the four bar, we have found even 3 rubber bands to be excessive! Wow!

We didn’t use 1x beams purely because we didn’t have them. I don’t know how much they reduce weight, but I presume that it is a lot. Do you have a video of your robot (if you’re willing to share)? I’d love to see it. I’ll have to experiment with more different numbers of rubber bands. Good luck.

Yeah I think that a couple things are wrong. First I’d change the front two wheels to omni wheels because the traction on the will slow down your robot a lot. I would also put an omni wheel in the middle because there’s lots of space in the middle ( unlike my teams bot) I would also put the arms close together because I can tell that their bending pieces but that’s just my opinion.

That’s not a very good reason to put something somewhere, it also adds for more friction and could make the robot slower.

If you don’t know what you are doing, then let someone else answer the question. Also, read through the topic before posting (unless it is a long Chit-Chat / Rumor Mill or something like that) because your first point was already made, and the second half did not have logic behind it, and evidence is important, otherwise people won’t take you seriously.

I’m sorry for posting things without doing research or evidence and will try not to do it again.

I hope you will not be discouraged to comment. Your heart is definitely in the right place in trying to help the other team and I know teams appreciate as much help as they can get. It is best to make sure that if you are offering assistance that there is evidence to support your claims to make sure that your comments do assist the team instead to setting them back as time to test prototypes can be very precious. Again though, do not stop trying to reach out to help teams. It is very much appreciated.
The others can definitely find a kinder way to telling you their point of view. Hope you continue to share your ideas and hope your season goes well.
Best wishes
