We recently competed in the Robot World Cup, held in Auckland, New Zealand, facing some very tough competition against some of the best high school teams in the world. While we are a college team, we followed all of the high school rules for this competition (other than alliances), including only using 10 motors and no custom electronics.
This was our demonstration robot, but we lent it to another alliance when one of their robots was seized at customs in LAX. It went on to perform pretty well! More photos and videos available at the link just below the image.
That would be a pretty odd coincidence. Some our other robots from this season have been named Java, Python, and Assembly. We don’t have a protocol for naming the robots, its just kind of ended being whatever programming language people have been learning recently, although I think we are going to avoid calling a robot C or C++.
Naming robots after programming languages is an inside joke - never released, but we had a spot as well - I want to name all the robots after the languages in the notepad++ library.
The extra wheels resulted in this being the most stable robot I have ever driven, unlike the first version of this robot (spot) which had serious tipping issues.
The lift isn’t a four bar, it’s a simple lift with chain to keep the intake parallel with the ground.
Edit: See this nice explanation here
The chain/tread that went on the sprockets was made up of repeating units each consisting of 3xHS chain links, 1x"Conveyor-belt Base link" and tall conveyor flaps.
Yes, only 3 HS sprockets (30 tooth)
Its capacity was 3-4 objects. Because it was originally intended as a demo bot, we didn’t bother making its capacity any more than 3-4
A note on the drive train: the 10 wheels were originally a joke but ended up sticking
In most robots with chassis which are 35 holes long, stability is usually not a problem. However, 10 wheels is slightly more stable, just from being heavier. I noticed that it is more “responsive” than some of our other robots, as it tends to drift less (as in when you let go of the controls, the robot stops immediately).
The drive was 1x 393 and 2x 269 on each side.
In terms of objects lift, we found (not on this robot) that lifting 5 objects put a lot of stress on the lift motors (when lifting at 5:1) and so we rarely collected 5 objects during match play.
Is there something in particular that you’re looking for that you would only find in a practice match? I don’t see why you would want a practice match video when there are already 20+ actual competition match videos available. If you can tell us what you’re looking for specifically then we can try to find you the correct video.
If you’re referring to this robot (Matlab) in particular, we don’t have any videos of it competing (or practising, or anything). We lent it to another team and the member of our team who does all the photograpy stuff was busy recording our team’s matches. So we have footage of our two serious competition robots, but not of this one.
