Team 930's bump strafe
 

Hey everyone,
Here's Team 930's progress going over the bump, as well as strafing on top of it.

Good luck!

WOW! that is really impressive. It will be interesting to see exactly what kind of role trans-bump movement will play in actually winning matches. If it ends up being important then your team should do great!

However, the way my team is currently thinking, crossing the bumps or going under the tunnels won't be that important and isn't worth the effort associated with doing so.

Re: Team 930's bump strafe
 

Very nice. I see you guys discovered the self alignment feature 4 wheel drives has when going over the bump as well.

Nicely done!

Re: Team 930's bump strafe
 

Great job BEARS! If you don't mind me asking, how much ground clearance do you have in the center of your robot? Thanks

Re: Team 930's bump strafe
 

Job well done.

Re: Team 930's bump strafe
 

To answer your question Mark, we are 5.5-inches off the ground at the center.

Yea we found the self-alignment a very key addition to our mobility when coupled with the mecanums. The only thing we haven't been able to do is strafe over the bump. Any ideas?

Oh, as well as going over the bump, this is short enough to go through the tunnel too right now with about 2-inches of clearance. But that clearance will change as we finish the robot. Obviously, their is much to add still but I won't spill the details.

that is really cool.

Thanks for posting that! It's always fun to see the great work that students are doing in this program.

thats cool!

but whats the point?

Re: Team 930's bump strafe
 

What do you mean what's the point? Mobility is key every year and when you can be mobile anywhere on the field where other people can't, you have an advantage over them.

This shows the mecanum advantage not only on the regular field, but on the bump as well. And when in the beginning of the season, no one was sure if they would even be able to get up the bump with mecanums, this just shows that it can and more.

Unless your wheel base is less than 12", your going to have a hard time moving around on that bump with any other sort of drive. And even if it is that small, it will be time consuming and difficult to go off the bump in any other spot than where you started.

Just think of it like a fight. Who ever has the high ground has the advantage. And if we have a way to keep you off the top, we have the advantage.

Re: Team 930's bump strafe
 

I was just wondering why you would want to do this, other than trying to keep people off of the bump?

And with your mecanums that could prove very difficult.

Re: Team 930's bump strafe
 

I can't wait to see how that is called. A bot strafing the bump to block another bot from coming over, then the second bot pushes the defending bot out of the way and it tumbles over. Will there be a penalty?

Re: Team 930's bump strafe
 

Hey man, unless your going over the bump at full speed, it will be a lot more difficult for you to push up when we push down.

And if you go over at full speed, we'll just get out of your way for obvious reasons.

Re: Team 930's bump strafe
 

Maybe other teams decided that mobility on the bumps isn't important so they did not put many, if any, resources into it.

Unless you have some clever strategy that I haven't thought of, I'm not sure I can see much benefit from being able to strafe on the bumps. Now if you could use it to climb onto the platform...

Re: Team 930's bump strafe
 

Well honestly, the bump strafing was never planned and ended up being a very nice bonus to our strategy.

But we really can't say until competition, the true bonus it really is. But we think it will bring some nice additions to the way we plan to play the game.
