Question: how did you vary the distance on the catapult to shoot at different angles?

In 2013 we started mating cylinders together to create a four position system. We repeated this concept in 2014 and have found it useful yet again. This year the two cylinders we stacked are the same length so we only have 3 positions. We fire one for a close (short) shot and both for a far (long) shot. Flow controls on all the ports help tune the shots.

As an example you can make out a set of paired cylinders in the bottom right of this 2014 pic. One cylinder rod points up while the other one points down.


Our other thread had a similar question and answer.

Great bot as always guys. Your team always puts together some of my favourite robots each season. Just saw that we'll be seeing each other at Smoky Mountain Regional. See ya in Week 5!

What kind of rope are you using for your winch/hanger?

I always love the designs 1986 puts out. Thanks for the inspiration!

It is braided spectra spearfishing line. 550 lb capacity and only .060 dia. The brand name is "SPEARIT", available from your local spearfishing store.

We are using a lot of spectra on our robot this year, mostly 1/8" diameter. It's amazing how many uses it has once you figure out how to splice and use it properly. Probably my favorite building material at the moment.

How did y'all drive those tape measures? And which ones did you use? (I don't need to tell you this, but that machine will dominate wherever it competes!)

Awesome robot as usual Titanium! It was great to see it in person at the scrimmage and we are looking forward to watching you in action next week at the KC Regional.

It never ceases to amaze me how 1986 finds innovative ways to solve complex problems. Also, having seen this machine up close, I was really impressed with how you fit everything in such a compact bot. That is a feat in and of itself.

Best of luck to you!

The tapes are driven by a enclosed motorized spool of our own design. It is approx. 6" in diameter and driven by the snow blower motor. We used the best ones!

Want to thank 1986 for showing 1108 this idea in 2014 so this year we have a pneumatic-height control on our intake/manipulator with four heights using the same method.

Creative programmer on our team has named the four height buttons on our console from lowest to highest: dungeon, stocks, gallows and Rapunzel.
Going with the castle theme...
