We did use polycord (that mention in the video is a misinformed parent
) We just used the connectors from McMaster to connect it rather than melting it together because it was easier.
We used chain on our shooter because we wanted firm mounting of our motors and it was a lot simpler with the way we designed it. Tensioning it is really important though and we definitely need some guards since our wheels go at about 3000 rpm. It takes seconds for them to slow down.
Chris, I hope we get a spot next to you guys again this year in Hartford. We did the last two years! I remember the plethora of teams we had in and out of our pit in 2010 trying to help us rebuild our frame (since it was a half inch over size limit and our wheel extended outside of our perimeter). Plus, its a bonus being next to a team that has a drill press in their pit!
To anyone who is discouraged about their team, don't let yourself get down. I've seen my team go from having a robot that barely moved (and I'm not kidding, we had keys falling out of gearboxes) to this year with a robot that is ACTUALLY GOING TO WORK. Don't lose hope, stick with FIRST!
I can't believe its week 6! Can't wait to see everyone is WPI and Hartford!
