Two Tube Autonomous Repeated 14 Times!
 

Re: Two Tube Autonomous Repeated 14 Times!
 

Way off-topic, but how did you manage to upload a video to GDocs? I've never seen that before.

And to keep this post somewhat on-topic: That's amazing! What is the light beam used for? Tube recognition?

Re: Two Tube Autonomous Repeated 14 Times!
 

Nice! Just curious as to how you plan to set this up with your partner. From the looks of it you would be running into your partner with how far the robot comes back and turns.

Good luck in St. Louis!

Re: Two Tube Autonomous Repeated 14 Times!
 

It appears they have bumpers set up on the floor to simulate another robot. This is truly impressive, well done!

Re: Two Tube Autonomous Repeated 14 Times!
 

This is awesome! Great work! :)

Re: Two Tube Autonomous Repeated 14 Times!
 

Impressive. Has anyone else done this without an active pickup?

Re: Two Tube Autonomous Repeated 14 Times!
 

Does anyone else not have an active pickup :rolleyes:

Re: Two Tube Autonomous Repeated 14 Times!
 

Very nice! The laser is a great idea too.

Re: Two Tube Autonomous Repeated 14 Times!
 

Hopefully you have another method of aiming for competition, the GDC has ruled that laser pointers are not allowed.

Make sure your peg heights are correct. The outer pegs are 8" lower than the center peg.

Specifically R02 d. Maybe it's just a concentrated lcd/led beam? Whatever it is, it's still cool though!

Re: Two Tube Autonomous Repeated 14 Times!
 

Also addressed in the Q&A forum. Search 'laser" in the Robot forum. This topic has come up many times.

Re: Two Tube Autonomous Repeated 14 Times!
 

They're using the laser to see where they are for testing, it won't be used in competition. Pretty clever, using a laser to check how accurately you can line it up using the tape stripes on the field.

(I think that's what Steve told me last night)

Eric from Team 610 here. A couple of teams could hang 2 ubertubes at Greater Toronto Regionals. Teams 2056 OP Robotics and Team 1114 Simbotics both did it consistently.

Re: Two Tube Autonomous Repeated 14 Times!
 

From the looks of it that set-up is immpossible.. Because of how far out the tower sticks out from the lane... The second tube is almost always 50% infront of the second robot...

Re: Two Tube Autonomous Repeated 14 Times!
 

I think they can get the other robot to be at enough of an angle for clearance to grab the tube.

Re: Two Tube Autonomous Repeated 14 Times!
 

Are you being sarcastic? I can't tell over the internet. I think my point was pretty clear.

Re: Two Tube Autonomous Repeated 14 Times!
 

I think your original message was a little strange, considering 842 has an active pickup.

842 just keeps getting better this year... now for the 3 tube auto? ;)

Re: Two Tube Autonomous Repeated 14 Times!
 

I believe Tom meant active pickup to mean something with rollers or conveyors.

Re: Two Tube Autonomous Repeated 14 Times!
 

Yeah, that's what I meant.

Re: Two Tube Autonomous Repeated 14 Times!
 

217 at Troy.

Re: Two Tube Autonomous Repeated 14 Times!
 

I was being sarcastic - plenty of teams have pinchers. I was more or less implying that any team with the resources to do this probably had a roller claw this year, since they are quite popular and effective.

Re: Two Tube Autonomous Repeated 14 Times!
 

469 at Troy

Re: Two Tube Autonomous Repeated 14 Times!
 

217 has a non-active pickup, and it works quite well. I haven't seen them with a two tube auto, but then again, I haven't seen them play since FLR.

Re: Two Tube Autonomous Repeated 14 Times!
 

842 had the resources to make an innovative arm that doesn't need an active pickup mechanism.

It's a neat robot, should be fun to watch it with pneumatics in StL

Re: Two Tube Autonomous Repeated 14 Times!
 

Both 217 ThunderChickens and 469 Las Guerrillas have a "grabbing" style (or non-active, as we're calling it here, I guess) pickup, and have a two-tube autonomous. 33 Killer Bees also have a two-tube autonomous, although their pickup uses rollers. All three used their two-tube autonomous programs at the Troy District Competition this past weekend; however, there was some measure of inconsistency for all three teams.

217 and 33 seemed to be having troubles with their programs during the semifinals, an issue that I credit partially with their elimination in the semis; however, 469's program worked flawlessly in the two finals matches that their alliance won. In fact, in Finals Matches 1 and 3, the Red Alliance was able to score all three ubertubes with only two robots capable of scoring in autonomous.

Re: Two Tube Autonomous Repeated 14 Times!
 

Great job! I like the concept of the double auto but i do not see it being used much in St. Louis. Most teams will probably have a well developed auto mode. Then again that is just me assuming since it is nationals haha.

Re: Two Tube Autonomous Repeated 14 Times!
 

During the finals it may be useless but in qualifying, many teams last year did not have an autonomous or are still working on it and we expect the same this year. Also who knows, the third robot maybe a super defensive box bot.:D

Re: Two Tube Autonomous Repeated 14 Times!
 

just wait :rolleyes:

Re: Two Tube Autonomous Repeated 14 Times!
 

Is this a practice bot?

Re: Two Tube Autonomous Repeated 14 Times!
 

I will tell you: trying to pick anything up with the pincer we had, I was very surprised I even managed to put any tubes up during competition let alone score with them...

Re: Two Tube Autonomous Repeated 14 Times!
 

Unfortunately peg height is limited by our ceiling. We'd cut out a hole, but the school wouldn't like that much.

As for the laser, squirrel was correct. We were only using it to double check our alignment to make sure we had consistent tests. Real robot is planned to have a scope.

We'll have to double check the starting positions again, but I'm pretty sure the plan for the auto seen is to start on the left side of the field, going for middle peg first. Changing the arm heights is not difficult, the hard part was making it land on two adjacent pegs consistently. Thanks for pointing that out, though... would not be a good thing to realize on Thursday at St. Louis!

With the amount of work going into it, I sure hope that it pays off! We think most of the qualifying matches won't have 3 auto-scoring robots on an alliance, so this give an extra 6 (potentially 12) points per match.

Yes, this is the practice robot. It's getting a lot of miles.
