'Snow Problem and GOFIRST are happy to participate in Robot in 3 Days for our second year! We have some new faces and some returning ones, and have been working over the last few months to make our build even more useful to teams.
Stream is back up, and you can check out our Day 1 video here.
We had some difficulties, mostly around half of our shop not having power for around 24 hours, which has held up some of our documentation efforts. We’re planning to release our CAD by around Thursday along with a white paper on the process we used to make our robot and information on all the subsystems.
As always, if you have any questions, feel free to post them here or on the stream!
That is a sick little bot you made! Two questions; I take it this captures a tower by parking on the Batter, and any chance of there being more videos of it interacting with the Cheval? There was a brief clip of it in the video but I’m interested in which mechanism you actually lowered the “ramps” with.
We capture by parking, correct. We faced both time and space constraint issues with attempting to climb while still fitting under the low bar, which was deemed our number one priority.
We have an L mounted to a motor on the back of the robot which pins down one of the pieces of the Cheval.
The device to lower the cheval de frise is a bag motor mounted to a versa planetary at 81:1. We didn’t have a chance to tune the shooter for that range, but I suspect that we could shoot from the outer works. It currently is set up for shooting from the alignment line.
In addition to the forthcoming explanation video, also look forward to our CAD model release, which will happen before the time it happened last year (week 5), and after I get a chance to clean up some parts of the model and get all critical subsystems updated to what you see in the reveal video.
We’ll also be releasing a complete breakdown of our strategic and decision making process here and on our website, which should be up tomorrow, and a written version of the explanatory video. As always, feel free to post in this thread, PM us, or hit us up on Twitter, Facebook, or any of our video pages.
Talk about driving it like you stole it, man, that was awesome! Totally jumped it! I love this game already. I thought you would have named it the General Lee. I think IRI should have “the biggest air” contest.
Awesome video! You guys did a great job, and my team has been thinking along the same lines that you have. Are you able to breach the portcullis or Category C defense from the neutral zone, or are you planning to rely on alliance members to assist?
We prioritized the B, D, and low bar defenses in our strategy and initial planning. While we did build the sally port, we never had a chance to test it to my knowledge.
We may try it on a practice field in the area at a later date, but we don’t have any definite plans currently.
Like Ryan said, we didn’t get a chance to test these items but there would be enough room to modify our manipulator on the back to do all of these. Theoretically it should be able to lift the portcullis and possibly open the sally port. Currently, I can assure you it would not do the drawbridge, but there are some simple designs we could do to solve that.
Awesome job guys! I’m very impressed with your robot. I’d love to see it in person at some point! Hopefully we can demo them at the Duluth and/or Minneapolis regionals.
