New VEX Game Announced!

[Chris is me]

If I was building a big giant unfolding wall of Vex plating, I'd just have the center stretch more than 2 feet. But a big, giant wall is unfeasible because your alliance partner can't break it either. A sliding wall on some kind of omnidirectional chassis, be it crab or omniwheel, would probably be better.

Man, why aren't there more Vex crab drives?

Well as long as you knock most of the footballs to the other side in autonomous it doesn't matter what your partner does, because you've nasically won, but the difficulty of build a mega wall is the major problem.

If you do manage to construct this "wall." What is the probability that you'll be able to maneuver as well as the robot which scrambles to score?

If you're up against a decent offensive bot, then the robot should be able to hold a LARGE amount of balls and then should be able to proceed and score them.

As easy as it may seem to build a bot with a large wall, I agree with gblake on that it won't be that effective during the match.

I can see a lot more slightly geared up drive trains. You could unfold a wall with 2 motors, then power the drivetrain with 8 and gear it up slightly. No pushing matches, remember?

Then again, heavy walls would make this a bit of an issue. Can you speed-hole in Vex?

If you don't like the existing holes, you may certainly drill more.

What about rollers for the wall?
Im thinking if you could lift your wall up past the goals then lower it in the middle of both of them and if you had wheels on the bottom of your wall so you could roll along it (omni drive would be a necessity) Then there would be no chance of being pushed away from the divider also would make for a very stable robot as the heavy wall will be supported by the field.

Well, robots aren't allowed to the cross the wall and go over the other side and you're talking about putting a wall down on the other side...I think you might get disabled.

Not quite correct

Robots are not allowed to touch the opposite side's tiles. Robots are allowed reach over/under the wall

Yes you're correct, but the post before me said...

I'm assuming the "it" is the floor.

Well, I guess 1977 is in VRC for this year also.

Well, we're only allowed 10 motors/servos per robot, and crab has to have each wheel independently driven. On top of that, we need two motors/servos to turn the wheels for coax. There are a few teams that use 6 motors on their drivetrain but not a lot, as most of them use their motors to build manipulators.

For this game I'm even contemplating using 2 drive motors geared for torque, just because I need all of my motors for the manipulator(s).
