Ok, it’s finally here! The moment that literally no one was waiting for… insert drum roll the 944B reveal! As you can see, most everything i could think about explaining is explained in the pictures themselves. Just in case i missed something, any questions or suggestions are encouraged! As for video, the most recent video i have access to is from October and can be found here: 944B Representing CHS at Westminster Ag Center - YouTube
Obviously, our robot has changed quit a bit since then, but the concept it still there to look at if you want. Also, i forgot to take close up pictures of the gearbox for the arm and it is a little complicated to explain without a visual example, so for anyone who has questions about that, feel free to ask, but i may have to answer you on Tuesday (when i go back to school). Well, thanks for looking at the thread guys!
dont think its a 1:16 drive ratio?
i think ou ment 1:1.6? 
looks great
and solo/practice vids?
Oh, nice catch man! It is most certainly 1:1.6, not 1:16. I did it in photoshop, so i guess i wasn’t paying much attention lol. As for practice videos, i left my camera at school, so i’ll get some content up for you on Tuesday!
For your intake if you have enough extra chain I suggest replacing the tank tread that does not have standoffs in them with chain… it decreases the weight and makes it easier to remove… and tighten the standoffs…
I have considered doing that, but with the gear ratio we have on the arm we can lift more sacks to the high goal then we can even fit in the collection tray so i don’t really think the small difference in weight will affect (or effect? i can’t remember when you use which one lol) the robot’s performance too much. Thanks for the suggestion though! I’ll get you some pictures of the gearbox in question tomorrow.
How do those kickstands work? They look nice.
So the ratio isn’t at 7:6; I was wondering how that could be done 7:1 gearing 1:6 sprocket ?
sorry, i probably shouldn’t have used the pokemon font lol. the “7” you see is actually a 1. And the drive is at a 1:1.6 (which i believe is equivalent to the high speed setting in the 393 motors).
the kickstands are deployed by the 2 pneumatic pistons on the back. They are held down by rubber bands in order to keep the robot from tipping on it’s back when we do wheelies under the trough. But since they are only held by rubber bands, the robot can still lean back far enough to fit under.
I got some video of the gear box, and we are nearly done some new modifications so you guys will get to see that later today!
Is the video posted somewhere?
Posting it now!

Bringing my camera to the club meeting tomorrow, so you guys are going to get to see the new modifications we have made!
