Robo-Cross B

i agree

[neapturkey]

Would adding treads from a separate VEX kit to my Vexplorer robot count as a functional modification?

[UQOnyx]

Possibly..
Do you have any documentation that otherwise, it would not be able to perform a task that it now can?

[jander14indoor]

The issue of what is a modification or not has been discussed fairly extensively on this forum already, at least as much as you can given this forum is NOT official.

I suggest you look back up the chain and find that. It will give an expanded version of what UQOnyx suggests.

FYI, we posted on the official event page today example documentation: http://www.soinc.org/robo-cross_b

I am Having trouble getting some of the things (the ping-pong-balls and battery located in the corner) does anyone know of a way to speed these things up? I am using one of the vex claw kit things.

Practice.

I've seen a mildly modified Vex claw bot run a 2:01 without rolling a ball. She could have shaved 15-20sec off of her time with some refinements.

We can pick up all of the ping pong balls without them moving at all.
Best time: 1:46.
Trials: 47

That's a good time. Most of our runs are around 2-2:15.
but our
3rd best: 1:47
2nd best: 1:41
BEST: 1:32!


Me and my partner are trying a new approach of picking stuff up with a new part. The first time we did it we got 2:11. State is on 4/18, so we still have time to shave it down.

Trick is not to use the claw to grab them, use special tools held by the claw. Much, MUCH faster and more consistent/reliable.
Will leave the precise solution to you to respect the teams I saw doing it.
From what anyone at an open tournament could see:
Hint, one way opening.
Hint, magnets.
Hint, the solution is NOT complicated. I love crude but elegant answers in SO. Pretty/refined comes later.

And practice ALWAYS helps.

Separate help on saving time. Don't repeat motions unless needed. Pickup 4 batteries, transfer to box. Don't pick up battery, transfer to box, pick up battery, transfer to box, repeat...
