1899 Saints Robotics Raw Video

Here's some raw media of our robot on bag day. In this picture and video, our robot had not yet had our bridge tipper and vision tracking equipment mounted.

We're pretty proud of having 25 girls in our 80 members, and getting by with a 1:12 mentor:student ratio.
In the video, shots were being fired at ~14 feet from 0:00-2:13, and ~17 feet from 2:13 onwards. We're firing at about 80% accuracy from 17' straight on, and 55% at a 30 degree angle.

This design was inspired by 1058's early prototype; it really sparked quite a bit of discussion among us!

Some basic specs and features:
-8" mecanum wheels, reduced around 1:35 from CIM motors
-4 Banebots RS550s on two CIMulators driving an 8" wheel
-Manually adjustable shooter angle (i.e. before the match), though we've found an angle we'd like to stick with for the most part.
-Two window motors operating the intake mechanism, with a third operating the regulatory wheel feeding the flywheel.
-Inclined side panels to allow us to tilt the bridge away from us to stabilize for our alliance partners. We're able to get on the [not competition regulation plywood] bridge without a bridge tipper period by timing our driving with the oscillation of the bridge. However, we're uncertain how this'll do on the competition field, so we're making an active tipper anyway.

Any comments or suggestions are appreciated!

Earlier in build season, we were considering using a flywheel-operated catapult. While we eventually scrapped the design, I'm curious about what others' thoughts on it are. Here's a CAD model of the carriage designed for the catapult, with the beveled part of the blade being front. Two flywheels would be pushed up to engage the blade momentarily.
