This is a no brainer, of course you guys should go with 20" mecanum wheels! Opponent's defenses will shriek in fear once they see this perfect defense damaging drive-train.

You need to make the rubber on the rollers thinner and then mount them on spinner-wheel hubs.

That bump you demonstrated is only one obstacle, and it struggled with that. Don't forget that there is a 4.5 inch bump, too. Also, the obstacle with the bumps that are different heights is 100% going to cause you to get stuck. Lets also not forget about the low bar, I think that is self explanatory. Lastly, every obstacle is metal, not wood, so you are going to crack a roller if you hit it to hard.

How are you going to be able to shoot or defend? You're not. If i'm defending and I see mecanim, I thank God. That makes my job 10,000 times easier becuase one tap and you're rolling.

Last year was the year of mecanim, this year's game has no application for it. Go with pneumatic wheels or kitbot wheels, you will have way more success.

Also I'm sorry, but the last time I checked FRC is a program for high schoolers, just saying:]
Thank you for your input. We have some disagreements when it comes to the true power of mecanum... but otherwise I have to say you make some very valid points. We have tried to get more student engagement but all they want to do is look at pictures of cats with something about 'haz chezbrgr"...

The choice of mecanum isn't a big deal compared to scouting. You need to find a high ranked team and beg them to pick you, that way you can be on the best alliance. Although, now that I think about it, they are probably more likely to pick you if they see your great mecanum drivetrain, so that's probably a good idea.

I literally can't tell if this post is a joke or completely serious. :confused: :confused:

Are you sure you want to post your design this early in the build season? What if someone else steals your idea?

Hello everyone we need your help!

We are an 8th year team and are really trying to improve from our last years performance. We really think our drive has a good shot of overcoming the obstacles.

We thought that 20" wheels would work well for us.

Please let us know if you think this is legal and a good idea.
So after a long strategic review I have come to this conclusion.
Why not make this a mecHanum drive?
If you used those wheels and in the center perpendicular to the wheels added a 20 inch powered drop omni wheel and a gyro you could easily have an unpushable drive base. If anyone pushed your sides you could push back with the omni wheel which should EASILY have enough force to handle itself in this years game.

You guys are so scrub tier. 8 inch pneumatic tire swerve. That's what pros use, yo. ;) lol

Wait...how...? :confused: Was this planned for 7 years? Is there a trick?

Does that count for posting before kickoff?

The upload date is just a trick. They actually took 7 years to build it ;)

So your strategy is to simply drive over the low bar? That's thinking outside the box!

I have to say, though, that a robot that could just drive over the Cheval de Frise without even caring would be pretty impressive.

Also, clearly the reason his "student" actors are so well versed in the robot is because the mentors spend at least 6 weeks coaching them on the ins and outs of the robot.
