 Earlier this week it took me a little bit too long to realize that the reason my pen wasn't writing correctly was that it was actually a screwdriver. I'm going to have to ask for a few nights of honest sleep before signing off on a report. - EricVanWyk [more] |

Falcon Robotics presents our drivetrain for the 2013 season. It features the Andymark KOP chassis except we put in 4" wheels instead of 6" wheels so that we can cut down the ends of the frame by 1" on each side making the robot 30.25" x 23.25." This lets us fit into the 54" cylinder more nicely. Our thinking for going with this drivetrain was that we wanted to spend as minimal amount of time on the drive as possible so that we can spend the greater majority of our time making our manipulators. Also, did we mention that this will be our first non fiberglass drivetrain in the last 8 years!

I'm going to miss the fiberglass drive you guys are so well known for.

What is the ground clearance? Is it low enough to push discs along the ground, high enough to drive over them, or somewhere in between where you are more likely to get hung up on one?

We'll probably have to do something about those boltheads that poke out of the bottom though. We'll do a lot of testing after we get it assembled for sure.

Nice looking CAD rendering 842! Curious though - why 4 CIMs??

Overall though we are really happy with this drivetrain. The tensioning system is so so simple. No maintenance once assembled except for the cleaning of the belts. Here is a video of it driving:Slow gear ratio

High and most likely gear ratio we will use:

Note that the reason the standard gearing is so slow is because we went down to 4" wheels for arm clearance reasons.
