Sick robot again guys. I can't wait until we see the final form of this robot once Championships rolls around. The way you guys iterate is just awesome.

Congrats and good luck!

Do you have any sort of gate at the back of the spatula to restrain the discs until the arm has reached the proper height for the discs to slide into the feed chute?

Very clean looking machine and very strong performer. I'm sure that a lot of work went into making it look so easy!

Re: 1986 Team Titanium 2013 Reveal
 

It doesn't need a gate since it looks like the arm picks up the disc by sliding under it, instead of using a motor.

Re: 1986 Team Titanium 2013 Reveal
 

We have a similar (but not nearly so elegant) "spatula" arm without a motor also, and we needed to put a servo driven "gate" at the back of it to keep the discs from falling out before the arm reached the proper height. I don't see any such thing on 1986's pickup.

Re: 1986 Team Titanium 2013 Reveal
 

There is actually a little lip that keeps them in. When we pull the arm up, the disc "pops" over the lip into the hopper. Also when we pick up two discs, there is a servo that holds one disc from entering the hopper until the other disc has entered.

This looks the most similar to ours of all the robots weve seen other than the 30 point climber, even the antenna that I bet most people didnt notice.

Great job!

You've got to touch the pyramid with something in the starting configuration. ;)

Re: 1986 Team Titanium 2013 Reveal
 

My favorite part of our 2012 robot was the zip ties we had on our appendage to touch the key while we shot so our wheels didn't have to be on it.

Jawdropping reaction from over here.

This robot is super cool. I can't believe that it's 114 pounds, shoots 3 pointers, and climbs quickly to the third level. Nice job on it!

Re: 1986 Team Titanium 2013 Reveal
 

hmmm, what to say that hasn't been said......

Hope to see you in St Louis.

Would love to see better details of the climbing mechanism. Is it similar to LOGMOTION (Final Force)?

Good Luck

Re: 1986 Team Titanium 2013 Reveal
 

I like how you have integrated your "spatula" pickup arm into your climber. When you climb, the arm goes to a position that isn't shown at any other time. Is there another cylinder that is used for this, or a 3 position cylinder that I can't seem to find?

Re: 1986 Team Titanium 2013 Reveal
 

Could you explain a little more how your picker upper works. You said earlier that it has a "lip", that the Frisbee "pops" over the lip and into the robot. How do you get it to "pop" over the lip? Is it the momentum of the Frisbee already going up when the arm stops? or is it something else?

Currently we don't have a picker upper, but at one point we did, it was too large for our robot (sticking outside of the 54inch cylinder). So I would like to add one back for later in the season, and looking at using something similar to this design for our robot if it works like we want.

If you could add pictures of video to the description of your picker upper that'd be great!

Thanks

A servo extends two aluminum rods laterally to create a new stop position for the arm. The arm actuation then creates the tilt needed to extend the sky hook to the next rung. The stop is retracted as we go for the 3rd zone so the arm can come all the way down. It's a bit more crowded at the top. :rolleyes:

We do have a 4 position cylinder (2 cylinders of different sizes mated together) to create the 4 different shooting angles. You can see the short one behind the long one in the autonomous close-ups (1:17) in the video.

Re: 1986 Team Titanium 2013 Reveal
 

We couldn't find small enough Rollerblade wheels to run it like 2011. :yikes:

Similar in the sense that it is an elevator on a winch. 2011 we had a cascade rigging with a 2 stage drum. This one has a continuous rigging instead. We had to be a lot more careful about how the cable spools this time since we have two sides that need to stay level.

Here's a clip of some forward court shooting from varied positions. http://www.youtube.com/watch?v=4hSRw04uurk
In general we have placed little stock in long range shooting because it is so easily defended, and shot percentage suffers. We prefer positions which are not defendable.
