The GreenHorns crew from NDSU is once again accepting the engineering challenge of epic proportions, that is Robot in 3 Days. Leading into our second season, we have 17 eager and caffeinated college students who are prepared for the tech trek that is upon us.
Be sure to follow our efforts as these next 72 ish hours pass!
The field element construction group is working furiously to finish the rest of the game obstacles (the moat, rock wall, and ramps are built already!).
As for electrical, the roboRIO is wireless, and the crew is currently working on the solenoids and the rest of the pneumatic system.
Build has made colossal progress as well! The prototype for our shooting mechanism has undergone numerous variations, each improving upon the other.
Our Meet the Team video should be completed soon as well, so keep an eye out!
Day One is looking marvelous for The GreenHorns. Another coffee break is upon us soon, however. #LifeofTri
Currently, we are working on fixing some chains-gone-astray that we found within our drivetrain system. Other than that, the drivetrain is looking marvelous! This is going to shape up to be one sharp robot when its fully complete!
Infographics are magnificent for getting information out there! Check out these ones that we threw together late last night! I would really like to see these used more in the realm of FIRST:yikes:
Mini CIMs in a 1:1 versa planetary direct driving 4" high grip wheels from AndyMark. When in taking they’re programed down to 90% speed and when shooting they’re 100%.
Wednesday night/Thursday morning I will be writing a white paper as well as editing our reveal video. You can see a lot of our functionality from the vines that we have been putting out, but you’ll need to watch our reveal video to get the full effect. I’ll just say that the 1114 style articulating arm is going to be highly effective… as will tape measure climbers.
As a pre-teaser teaser here are some of our robot performance specs:
Height: ~14.5"
Low goal with 100% accuracy
High goal capable (a good driver and some sensors would make it deadly)
Touch-it-own-it intake
Winch with hook for climbing (just didn’t have the resources to get the hook to the bar, tape measure climbers with detachable hooks!!!)
Capable drivetrain that can traverse: Low bar, Ramparts, and Rough terrain (if we had access to 2 more 8" pneumatic wheels it would’ve been a much better drivetrain)
And the best part… it’s only 72 lbs. The only necessary addition is the device for getting the hook to the bar. There’s so much weight for additional functionality. It’s more volume limited than weight limited, so if you’re creative you can have one heck of a robot.
Thanks so much for replying, and to you guys in general for all your hard work the last few days! Also, can’t wait to see that reveal video/ read that paper.
Well after sleeping for a combined 6 hours the last 4 days, your sleep schedule gets shifted. Plus it’s build season. Any chance to help a team be more successful is one I’d jump at! Good luck this year!
I have one last question if you will indulge me; what is the center to center distance between your shooter wheels, It seems like you guys are getting the perfect amount of compression?
