We decided to post the robot we’ve been using for most of this season and the one that qualified us for worlds at State last weekend.
This robot is an Arizona State Champion and the Arizona Programming Skills Champion.
Out of the 7 tournaments this robot attended, we won 6 and got the excellence award and finalist at the 7th. We also got the excellence award at two of the tournaments that we won and the design award at two more. We got first seed 5 times, robot skills champions 5 times, and programming skills champions 6 times.
Our highest official skills scores were 50 for programming and 73 for robot skills. We did get 73 in programming skills once but it was not an official run… Dang.
It’s a side roller, 6 bar bot with a 15" long drivetrain and a 35 hole length arm. We used 4 393s on speed gearing for the direct drive, with a loose chain to connect front to back. 4 393s powered the lift at 5:1 for most of the season but we switched to 7:1 before state to make hanging easier. The intake is 1.6 geared and went through several different roller revisions.
The robot could hold two big balls in some cases, but was usually limited to one. We low hung with a big ball throughout the entire season by lifting and swinging back to land on the wall. This was about 90% reliable with the 5:1 and absolutely 100% reliable with the 7:1. The robot weighed in at about 11 pounds after all.
Please ask any questions you have about our robot and we’ll be glad to let you know anything you’d like!
The robot served us extremely well and definitely achieved our goal of securing a Worlds qualification at State. We’re excited to see you all there!
