So on the VEXCast in the past I have talked about how to build a 2 motor robot that could qualify in HS through skills. This is the global skills rankings to be clear, it would be even easier to qualify through some regions skills competitions. I decided to attempt the robot, gave myself a couple movies to watch and expected an all nighter. Took roughly 5 hours to construct and because I was in a hurry I used 4 motors. So I call it “the little robot that could”. Capable of 320 programming skills. Averaging roughly 1.5 bps and driving perfectly straight across the field to line up.
Videos and code to be included in later posts.
Edit: This robot was very heavily inspired by 8059 's skills robot.
Are those black #32 rubber bands? How many did you use? How far did you pull back.
I’ve been playing with a puncher just to demonstrate the concept to the team, but getting the bands and pull back length correct is tricky for me. Maybe it has a lot to do with build quality?
So in the end I used 1 size 64 rubber band on each side. This should be similar ish to 2 size 32 on each side. The build quality is pretty important for making the slide have low friction but in all honesty it isnt that difficult. I would suggest ignoring everything like gearing it and just set up the structure and pull back manually and see where the ball goes. I had a few instances of shooting the puncher before I put a stop on the front while doing this. (Still apologizing for hitting my girlfriend in the face with the puncher when it went flying.)
Ya GOAT competed with it at a recent competition. 1 robot on the field and 4 motors. Only ever did like 271. The robot could do 320 but loading fast and accurate is hard. A few of our runs a ball would miss on the close side, bounce off the net knocking over a stack into our path for driving across the field. This then made it not line up correctly on the other end. Life happens sorta stuff. Anyone who was there would agree that it could have done 320 perfect given a few more runs.
So it’s the Little Robot that Could have scored 320, but that Didn’t.
I’m just kidding. No that’s actually really impressive and does support an interesting point about how easy it was to score high in skills this year with a dedicated skills robot. Yet such a robot would not be very good for a match. Then you have hybrid robots and others that are good at both but require a lot more work.
It seems in past years the robots that were good at skills were also the best in a match. Is this perhaps the first year that this was not the case, or am I generalizing?
Every season, there will be specialised skills robots.
Eg. Last year, one of my teams had a robot that couldn’t move but parked right at the starting tile. But it was good enough to build 7 skyrise sections and 1 cube.
Good enough to make it to world with that. But it will be thrashed at world.
This year, obviously we had a team that built a specialised skills robot too. But with a bit of modifications and addition (which they did), think they will do pretty well for World
