This video is absolutely gorgeous (as is the robot). I had to watch it again to see what the robot actually was because I spent the entire first viewing gawking at the cinematography and editing. Nice work!

Really amazing video. Probably one of, if not the, best filmed one I have ever seen.

How well does your intake work? Does it kick the ball away at all? Any reason you chose it over a roller or El Toro intake?

Works surprisingly well. Always clinches the ball perfectly and I've never seen it let go.

We chose it to make it simpler.

Lowest cg bot I've seen thus far. I bet it's fantastic to drive. Great work guys.

Can you post some pictures of your robot

Compared to last year, it feels like F1. Our CG was very important to us because we rely heavily on quickness and running shots.

Gotta love the Nifty Fifty! Loving the focus pulls. Kudos to your videographer.

Does your camera guy use Magic Lantern? It has oodles of neat features for videographers (my personal faves are the audio-bars and focus dots).

Signed a fellow T2i user (Sigma 17-70 2.8 FTW!)

I think so, I remember people talking about custom software on his camera. I can ask him when I get a chance.

Yes, he is. I remember him showing all of his custom setup options.

This reminds me that I still need to make a dolly and tracks for my build season videos. I didn't even have my stabilizer, but I managed.

I also need to get my own camera. The one I use is our head coach's and I think he has only one lens, so my variety isn't tremendous, but I do my best.

My cousin and I are actually starting a little independent film company project, and everything we record will be in 4k, so i'm pretty excited for all the new equipment we're gonna get, and I hope I can use that stuff for future build season videos.

How many people worked on this? I'm the only one on my team that knows how to shoot and edit in this style, but I want to teach the students in the future.

Wow. Fantastic robot, and another example for needing a reveal video award. This is the first reveal that made the audio come front and center other than picking a sweet song. Kudos to the audio team/foley artists...

Thanks for 4334 viewers everyone! We appreciate everyone's kind words.

Question. I noticed the bouce/deflect pass strategy you used in curie elims, I assume you did it before I just never saw.. Where your human player appeared to throw the ball at your shooter in the fired position and the shooter would simply deflect the ball back at your human player through the spring force applied to your catapult device. You were of course credited with the assist.

I had a similar idea from day one, but I never asked on the Q&A about it's legaity because it did't seem to fit the motion relative to the robot bit. Did you ask on the Q&A about the potential leagality of the strategy?

I guess I can see how the spring force that the ball being thrown at the device can cause motion relative to the robot, but I was concerned that since robot didn't generate the force other than the reaction force to deflect the ball it wouldnt be considered legal. I obviously see it was since you used it at championship. I honestly just want ro make sure that is actually what you were doing so that I can go back and employ the same strategy in the off season.

The refs were skeptical at first, but the bounceback was ruled as possession because it was in effect "pushing the ball back". Honestly it wasn't a complicated or well thought-out thing, we just had the idea and asked to see if they'd rule it a possession before thinking too much about it.

And the reason we didn't do it too often was a combination of wanting to finish for our alliance and secrecy of the strategy (118 & 254 were the only teams that we knew were aware of what we did beforehand)
