Re: Are extensions with bumpers after the start of the game legal

We will retrrack the extensions prior to moving to deploy the monibot.

We still have to figure out if that break in the bumper is OK. if not we have to figure out another way to get the extensions down. We are planning on making each extension close to 25lb by putting some of the heavy system components in them.

The bot looks good, I'm glad you're aiming to make the minibot - resist giving up on it! :-)

A few important comments:
1. Currently the the robot's true bumpers have a small cut-out in them for the "outriggers" to fold through... Those are unfortunately not legal. The robot's bumpers are required to be continuous all the way around the robot, with no exceptions. <R07A>

2. I'm glad you're certain you can fit within 84"! I feel harsh in asking, but will the bottom edge of the "outriggers" extend outside of the 84" while unfolding?

3. You're welcome to construct whatever you like for the "pseudo-bumpers;" however the bumpers that go around the 28"x38" robot must be regulation... I'm not sure if it's just the model, but the regulation bumpers have only two pool noodles - not three stacked on top of each other. <R07E>

4. A not so significant comment... It seems like there are many frame members... I have no idea what your wait looks like, but be sure you have wait for everything... From experience, as soon as a team takes the attitude "wait isn't that much of a concern!" the robot ends up overweight. Make sure you include things like wires, fasteners, and chain in your weight roll-up. Those can add as much as 15+ pounds on the entire robot!


Looking good - I admire your teams' innovation, open designing, and willingness to take risks! Best of luck!
