I didn't have much footage / photos of the building process, but I tried to explain as best I could. Please feel free to ask any questions you have in the comments or on the Vex Forum: www.vexforum.c...
I really like the DR4B Tray design, I think that this is probably one of the more competitive classes of bot for this year. Really clean build, looking forward to the next iteration :)
It's held in by axles with a notch in them. When enough force is applied by the bands on the lift it forces the axles to go up and to release the anti tip. In a further design I used a flap to hold the axle up a little and used a post on the lift about flat so that when the lift raised past a certain point, the post rotated down and released the rubber band so that the axle was captive. The lift had a ton of gouges from the axle flapping around and getting caught between it and the drive.
Ian Talbert I just saw the forum post. Great job! I am not sure that stacking 17 cubes is super realistic based off of that there are only 66 cubes, which would be 11 cubes in every zone without towers, so...
