I was thinking the same thing. What if a bot on an opposing alliance shot balls into their hopper when they were already carrying 3?

Most likely, the opposing alliance will incur a foul while giving our team another ball to shoot.

What's the purpose of the pneumatic piston on the rear of the elevator? My first guess is hood adjustment, but with the rivets running down the hood I'm not entirely sure.

It's just for achieving a steeper trajectory, similar to 968 in 2006.

You California teams sure make some shiny robots! The ball harvester pivoting on the same axis as the roller is a nice touch, and I like the pivoting shooter hood. What is the material for your rollers and shafts?

Under what rule?

[G44]
Generally, a rule violation by an Alliance that was directly caused by actions of the opposing Alliance will not be penalized. Rule [G28] is an exception to this rule.

While G44 covers the actions of an opposing alliance, there is nothing that would prevent the actions of an alliance partner robot from causing a four-ball possession foul in an open-topped hopper. Accidents like a bouncing/missed 3pt shot could easily land in an open hopper if the robot was close enough to the fender.

Nice looking robot Kiet. Nice touch on powder coating the wheel rims. Hey, what are you using to join the shooter hood side to the shooter hood top?

I think you'll like what you see from 696 this year too ;)

Considering their robot is 119lbs, I wouldn't have made a gate for an open hopper when the chance of getting a stray rebound is small much less when you have there in your robot.

We played around with making a gate on our robot but it comes at the opportunity cost of getting your other mechanisms working and into your weight budget.

We've played around with throwing balls into the robot and it's not as easy as it looks. The ball has to bounce just right for it to land into the hopper. The top of the hopper sits around 34", which is just below the opening of the inbound station. We wanted a low, open hopper so that we could drive up to the inbound station and have an inbounder drop balls into our robot.

wow, i like the basket for human loading. Nice looking bot, can't wait to see it up close in San Diego. :)

Yet again another clean and formidable looking robot from the Holy Cows. Great job guys.

Thanks Dave! They're just held together using lots of bolts. It's hard to get away from a previous team in terms of robot design, isn't it? ;)

Also don't be surprised if you get a violation for rule G21. Our team was at a mini-Regional, with the head inspector from the Wisconsin Regional there. We had a ball pickingup device, similar to yours.It extended partially beyond the frame perimeter. He declared that it was illegal, since the polychord was not contiguous. It was within the frame perimeter and then outside the frame perimeter, as it rotated, attempting to pickup balls. Because of that he said we'd be hit with a rules violation. We were forced to redesign our unit, so as not to extend beyond the frame.
