I really like the way you use a simple bottom roller to intake cans, straighten misaligned totes, and exhaust the stack from your elevator in a very smooth and controlled motion.
Other than the fact that the drivetrain look a bit fast for the distance you're planning on driving, I really like the rest of the design. |

Nice job!
I loved your 3 ball auto last year, and it looks like you have a solid robot once again. |

VERY happy to see someone else doing an "internal" stack. Seen plenty of cool external forklifts so far.

this is the first day of practice so we can still do a fair bit of tweaking as we see how it performs |

Very similar to one of our initial ideas, but we opted for totes outside of the bot instead of inside, for simplicity's sake. Really great job. You guys will make for a stable and reliable 6 stacker.

Killer robot guys. Looking forward to playing with you at SLU and seeing this one in person.

Robots like these...
I see them and then smack my forehead... Simple...efficient...effective...Amazing. Great job guys! Edoga |

Very very efficient and ingenious extract of totes onto the platform. Not much room for tipping (unless of course your alliance partners nudge that stack). Looking forward to seeing it in action!

ye it ended up being much simpler than the initial designs as we iterated. that roller was originally an entire conveyor belt system, but as we did some testing we noticed it was completely unnecessary so we ditched everything but the front roller. the external swinging fingers where going to be an entirely different system that would laso the game pieces but again through iteration and testing this system was also reduced to be as minimal as it is. However, we did end up making one system much more complicated than original designs, and that was the flappers that drop down to grab the ledge of the totes to pick them up. We tried a passive approach initially like many other teams with bent poly-carbonate but weren't satisfied with stability of picking up a stack so this turned into a rather complex system we had to iterate on a few times and tweak to make work properly. There is a passive reset for them and we use servos(as you can see in the video if you look closely) to activate them. It's more complex than I would like but it seems to be working perfectly without any issue every single time so i'm not worried about it anymore. |

I take it from the video, you can also stack RCs in a horizontal position as well?
