One of my team’s ideas for scoring power cubes on the scale was to launch them. I know Ri3D Snow Problem has tested shooting them with their 2016 robot with fairly good results. Have any other teams tried shooting power cubes with their 2016 robot, or 2014 robot to get an idea of the amount of power needed to do so?
We used 775 pros with 4:1 VEX versaplanetary gearboxes on them running at full power. The max height we’ve achieved was 6 feet out of the about 7-8 we would like to hit. It’s definitely possible to do with the right amount of tuning.
We have a video of 'Snow Problems final shooter up on https://www.youtube.com/watch?v=2GG5NEalEFE). With 4 775s at 9:1 and 3:1 at 100% we shoot about 11 ft up and 7 ft. over. Our reveal video should come out later today which better shows it’s capabilities.
How far you planning on launching them? Search the rules for “launch”.
Honestly coming we thought it would be so hard to launch these cubes after doing the math with our design we roughly have to only launch the cube about 24 inches to score on an even scale. Upon seeing 'snow problems design with launching we are pretty hopeful with our prototype. The only question we are working through now is if its better to have one shooter wheel or multiple to contact the cube at different heights.
I’d imagine multiple would be better for gripping the cube. Both Ri3D 1.0 and Greenhorns have shown that the cube loosens a bit when moving it around to score. Now, take what I say with a grain of salt because its only a video and it was built in 3 days, but I guess that’s just some food for thought. A lot of time would be wasted accidentally dropping cubes and going to pick them back up.
