As the US Open is getting close, we figured that we should post a short reveal of our robot. This is version 5.0 of the the robot, although the overall concept has remained relatively the same since early August.
Specifications:
Drive-
x6 393 motors set at 100 rpm
4wheel raised drive base with a chain-wrap at 1:2
Very fast and can easily maneuver the bump
Lift-
x2 393 motors at 100 rpm
6-bar lift geared 7:1
Reaches well over 24"
Intake-
“Magic Intake” set at 160 rpm
Rubber band wrapped sprockets as large ball intake
Does not have to pin large balls to intake
Thrower-
Throws out the back of the robot
x3 D/A cylinders (used as single acting)
Three reservoirs allow for 15+ (good) throws throughout a match
Can throw over the barrier without raising from the hanging zone
Can completely descore large balls from the scoring zone
Can hold three buckyballs and still throw large balls
We have had a fairly good season. We ended up winning three local tournaments, including the Indiana State Championship (With 323z and 1115c). Our unofficial robot skills score is 90, but most of us know how that goes! I don’t have much in the way of a formal reveal video, but I think we will have a more in-depth reveal closer to Worlds. I linked a video of the thrower from my phone and I’ll link a video of the buckyball intake as soon as I get it uploaded. If you have any other questions, feel free to ask!
After a lot of testing we have not experienced any issues with either the thrower holding up mechanically or with the the large balls not being adequately held within the thrower. The arms are also far enough apart that the large ball will sit down securely within them.
The flaps originally were cut for the last version of the intake so that they would not hit the pieces of c-channel that held the rollers in place. On a whim we tried them reversed on the new intake to see if they had a noticeable effect while taking in large balls. We found that they do not affect the performance of the buckyball intake, but they do allow the large ball to be more easily pulled over the rollers.
This looks like a great robot. Ill be sure to stop by your pits and have a chat. Best of luck to you at the Open! Jesse (323Z) says you guys are a powerhouse and I can see why.
