ok so still anything posted is fine but I’m specifically looking for ideas for the rollers eg how to make intaking more smooth
I do not really understand why you would want to “acquire” the scored cube. we just push it out while reversing our rollers.
By aquire I mean grip
This is their 126 or run:

One improvement traybots can have is to have a gate mechanism in the tray so it can hold cube while the 2 bar is still able to go up and score in towers

well anyhow a 2 bar works great for me and I don’t intend to build a lift
it’s 6 towers and 18 cubes. it’s actually quite easy to accomplish once a driver gets enough practice in. and by enough I mean hundreds of repetitions to get everything right. but that’s really just a matter of time.
i agree. but mechanical and coding optimization could have prevented their tray and arm getting stuck half way and saving vital seconds maybe to push another cube into the scoring zone.

Is the 126 in the video title incorrect or am I scoring this wrong because 6 * 18 = 108
The cubes are a baseline one point and the towers increase their point value by one. Therefore, having 6 towers equates to 7 times the score. So if they had 18 cubes and 6 towers, they get 18*7=126 points.

so. how do we prevent the tray and arms from getting stuck .I’m preferably looking for a way to completely isolate the two(make the tray not get in the arms way when lifting)
Build quality and coding are the two main ways that you can avoid the lift from getting stuck. Make sure that your arm can not wiggle a lot and is very stable and sturdy so it doesn’t catch on anything during its ascent. Also, make sure that you code the robot so that the tray moves forward while the arm is lifting so it doesn’t catch on the tray. If both of these things are perfected, your lift should not catch or fail very much.

2 separate mechanisms having any interaction at all without motor sharing is imo poor design. goofy is great as a early mid season bot but optimizations on the arms’ structure are necessary imo

Josh, they actually scored 18 cubes and 6 towers. 2 stacks of nine and a bunch of towers. Their run is now on YouTube I think.
Their programming skills can be found at 5:36:45 on the video called something like “Kids Inc 4H tournament 10/26/19” (sorry can’t link it right now). Just a helpful resource.
Yeah, I made that post before I had seen the video.
Don’t worry though, we’re prepping for skills at tower of terror. Good luck!
