I also think the clock on the robot was genius as drivers can't afford to look away from the robot.

As it stands, we can hit from 2.4m from the wall. I think with tweaks to the code we could get a bit further away but not too much.
There are mechanical tweeks that can help as well. The green cords (that I love so much) did not seem tight enough. I suppose that tighter bands or more of them (it was rigged for two per motor but we never got to it) will help get more velocity to the ball and improve our range.
In addition, we currently have a 2:1 stage in cord and a 7.5:1 in chain. I think there is optimization to do on the 2:1 stage. Maybe a 3:1 is better, or maybe a 1.5:1?
Now that we have code control, I would like to think about using chain on the first stage (limiting impact loads at the end by controlled decel of the arm). Again, I LOVE that green cord and more folks should consider using it but I love capable robots more. The main reason we used cord was to protect the chain from snapping during impact loading at the end of travel. If we can avoid this problem using software and the robot has a vastly improved range, then. my love for green cord not withstanding, I'm voting for chain.
FINALLY, if 2 (340W each) CIMs are good, won't adding 2 (270W each) Banebot 775s be better still?
That is the beauty of finishing early. Time to experiment and to improve.
