 Well, we put it in the bag at 11:58 last night. Needless to say we had to pull guys off of it to put it in the bag. I hope we didn't miss somebody and bag him up too. - jimwick [more] |

We're proud of this year's robot-we definitely learned the value of "KISS" this season...
I think our robot deserves the "Most Purple Award", don't you?

It doesn't even look to have enough clearance to pick up balls, does it really squash them?

How does your robot work? It's the closest looking robot to my team's robot (201) that I've seen so far.
It is very purple indeed

The roller system compresses the ball about 3 inches

Alex:
Essentially, there are two sets of belts connected to two rollers each, one set in front and one in back. Pickup, despite the appearance of not having enough clearance, works very smoothly (yes, it does squash balls somewhat) and either feeds into our hopper in the back or shoots out of the top depending on the situation.
The front rollers are powered by one CIMWalt, while the back rollers are powered by a CIMWalt and a FP Dewalt as well. We can empty our hopper in around 2 seconds.
In my opinion, one of our best features is our rotating turret with automated tracking, which is able to switch between targets that are in range and follow them accordingly. Another cute and useful function is that when a trailer is in range, the fire button lights up on the control board!

And your camera program sounds awesome! Do you just automatically dump when you are in range?
And where is the camera?

definitely the most bullet-proof robot we have ever made. And not to disappoint, it is indeed totally constructed from wood, from the rollers to the chassis.
The belt system was designed from the ground up to have the belt speed be the same as the firing speed, causing the balls to move at extreme velocities though the entire system, and making for a very rapid reload and firing cycle. this allowed our robot to play a "running and gunning" strategy that worked effectively throughout the Lone Star qualifiers

Congrats to 418 on their Chairman's award win at the Lone Star Regional! Are you guys going to Atlanta?

Off topic for just a sec -
Frank, I wish you would post a photo of your 'wings' that you created and wear at demos...those are so amazing...
Ok, back on topic:
Aristophanes.

I believe you guys have only slightly more purple than us this year...
But it's definitely close. We'll have to have a contest for that award!

We also have built into our OI a tactile response to alert the operator to a belt jam. When our robot detects the belts not moving when they are supposed to be firing or intaking, the control panel vibrates with a buzzer. The operator can then reverse the belt direction to dislodge the jam.
