paper: 2014 HOT Tech Notes

[JesseK]

Interesting design analyses.

I thought 254's '08 bot was a much better bot to emulate for this year's game than 1114's '08 bot. Simple lift, softer launches and a similar roller intake/outake - much more controllable than a punch. I suppose c.g. would be an issue, but with the ball in the 'up' position c.g. is an issue with 1114's design too.

Turns out either would work for specific robots, but 1114's probably better for the high goal. Yet I was more biased towards being the best ball handler than the best high goal shooter.

I can't speak for HOT, but oddly enough this exact same logic is why we went with an 1114 claw. Building a bulletproof claw intake was way easier for us, and the rest of our design was driven around the claw.

Beautiful machine HOT. That backwards fire is so clutch, can't wait to see that win you some matches. Squeezing every second out of a cycle is key and it looks like you guys have it

We like both designs as concepts to work from. But we felt that the 1114 design was superior (atleast in 2008) for both ball collecting and high goal scoring.

As Chris mentioned, we basically started with the claw concept and designed around that.

One of the biggest benefits we saw in the 1114 design was the ability to get balls out of tight spaces. It's still pretty true....but the top roller with out side bars does require a higher level of driver precision than the Bombsquad (top roller and side bars design). 1114 had one of the best drivers EVER in 2008. Teams should take that into account when they are evaluating designs from past games.

We will probably need to add something to our design to assist with ball centering to make it easier to collect the ball. Right now that is one of the areas we can improve on greatly.

Great read. I always love looking at any robot 67 builds. You guys have made some great marvels of engineering and this year is certainly up to that standard.

Thank you so much for this. When our team did terrible in 2013, I spent days looking over things like this. I ran into your tech notes and it was like I struck gold. I showed this to our head engineer and we decided to do what you did. We used waterjet 5052 1/16" aluminum and lowered the pneumatics use. We also did our own little spin by adding some mounting holes, cable management holes, and some strain reliefs built in to the chassis. We even had to buy our own 5052 stock because Chrysler (or fiat now ) only had 6061.

In short, thanks. This really helped us get a good base down to start tinkering with.

Chad, thanks for the kind words...I'm glad that the tech notes are being used.

We were really impressed with your machine and driver's at Howell. Keep it up!

Looking forward to seeing you in Lansing.

Adam,

Thanks for sharing the Tech Notes again this year. I finally got a chance to read them, after watching some of your matches of course. It is always cool as an engineer to know how something works and some of the thoughts throughout the process.

Good luck the rest of the season and hopefully I can see this beast of a machine at Champs!

Since we weren't able to finish our premier night reveal video in time, we waited until we had additional footage to publish a video.

Fresh from the HOT Team Promotional Department is a video featuring our robot at the Howell District: https://www.youtube.com/watch?v=pHBzLlr8aso

Additional videos from Waterford can be found here: https://www.youtube.com/watch?v=-AGQ...zK-g_bv4hkgwwd

Enjoy!

Enjoy!

Good song choice. The last time I remember a team using that song in their reveal video they won The World Championship.

Nice!!! I wish I could say that was intentional, but unfortunately that might be the only Robowrangler video I have never watched.

But, I am not suprised that us and 148 would choose similar music:
