+1! And by the way, Dr. Joe, what tape/wrap did you use on your acquisition wands (torro sticks)?
Good job all of you, very impressive!
This will help a lot of teams head in a productive direction.
Not necessarily copy a design, but inspire them to think of somthing they hadn’t considered.
Cheers to Ri3D teams
Sorry you don’t agree with my opinion on this. But it has not changed and based on posts in previous threads that I had not read prior to today, I am not the only one. However if this type of thing helps even one team then you got what you were going for. Cad drawings and a BOM will be even more helpful for teams.
Glad I was wrong, rewatched on my computer (originally on phone) and I can just see that 2nd finger.
More details to come but the best stuff I know for this kind of task is Abrasion-Resistant Natural Latex Rubber from McMaster
I like the 1/16th thick rough on one side stuff (86085K2)
Again, more details to come.

While we at Team AndyMark chose not to complete our Robot in 3 Days, we did get much CAD completed.
Here is a .STEP](http://files.andymark.com/Full Robot AM-Ri3D.STEP) file and a Solidworks Pack and Go .zip](http://files.andymark.com/Full Robot MIdnight Special.zip) file for folks to see.
At this point at AndyMark, our main focus is to support our customer base and keep operations humming. We also work with some local FRC teams, and those teams will be helping us complete and test some of our prototypes and designs. However, we aren’t going to force the students to use the designs we made during Ri3D. Due to weather, the students have not been able to decide upon an overall concept. Hopefully, our design work may be able to help them come to a conclusion.
Sincerely,
Andy Baker
Count me among the people who’d love to see:
A) Team AndyMark’s robot finished, regardless of how much extra time they need.
B) All 6 72-hour robots (Ri3D 1.0, AndyMark, Boom.Done., O-RYON, TeamJVN, and TeamCopioli) in one place, with a field, playing a MATCH (or possibly a small tournament) of Aerial Assist, before the end of build season.
Great idea, or somthing like that, maybe some mock matches with mock officials that know the rules, robots and teams to play out real scenarios.
It would be great to watch some actual matches play out, this would help teams figure out what will actually happen at competitons without learning the hard way.
How many times have we said “hey I didn’t forsee that happening” or “you can do that?” :ahh:
Will this actually be a FRC’s teams competition robot?
Even though it’s completely impossible. I think It would be really cool to see these robots compete in an actual regional. It would be interesting to see how they size up against what everyone else builds this year.
No. I love it way too much to risk letting some high school kid drive it like he stole it 
Joe J
haha.
Have you tried other materials for the intake system? A very popular sticky item back in 2010 was Dycem, I even pushed to use it on our floor intake last year.
Thanks Dan.
Would it be possible to provide a version of the Ri3D1.0 video with subtitles? Or maybe just a version with the background music completely muted when people are speaking? Their voices are muffled and I cannot understand what they are saying. Thank you.

Those are some pretty impressive robots. Is it true that nearly every team will be releasing their schematics and code for their robots? And if so anybody find any crucial flaws that would be difficult to overcome during a regional. I would love to talk through some of these designs with my team.
Dr Joe,
- Can you also quickly comment on the Versa planetary gear ratio you used on the torro sticks and I’m thinking about ordering those today.
BTW, the motor/chain powered launch mechanism is leading me away from a winch/catapult style design for my team.
Regards,
Marc Center, FRC3548 coach
Dr Joe,
Out of curiosity, how did you fasten the “toro sticks” to the Versa planetary output shafts? What material are they?
Toro Horns. Schedule 80 PVC (thicker wall than Schedule 40). I heated up some 1/2" hex shaft and melted it in place so that a Versaplanetary shaft fits tight inside.
Very happy with the result.
Dr. Joe
The VersaPlanetary set up is this:
- Banebot 18V motor as input (crazy overkill but when you are building a robot in 3 days you use what you have in hand and once you find a thing that works, you don’t change it unless you have to).
- 4:1 stage 1
- 5:1 stage 2
- 1/2 hex output.
I love the versaplanetary system. I think they are a huge help to teams prototyping because it is so easy to change the motor or the ratio or the output shaft. I’ve got no financial stake in the product or company, I recommend buying a boatload of ratios and output styles (1/2" hex and 1/2" round are my preference).
Calling 'em like I see 'em.
Dr. Joe
Dr Joe,
Thanks for your answer.
Sticky material (dycem?) from a previous post (Alex Cormier) found can be found at andymark here http://www.andymark.com/product-p/am-2454.htm
This may be a suitable substitute for the natural latex rubber product you used from McMaster-Carr, but needs testing for confirmation.
Regards,
Marc Center
I agree with Andy Grady on the judging show: El Torro will be the single most copied mechanism this year. To all the teams participating, good job, and thank you all for your time and effort.
Dr. Joe, if it’s as planned, we may have a robot named after you (we have a tradition of naming robots after people)
