1629's Tripple-shot from center zone in Autonomous.
 

Just wanted to post this clip showing our favorite Autonomous program...

Planned for if we have an alliance partner with no auto mode.

Looks really good.

From what I've seen, rolling the balls into the goal is much more efficient than kicking them long range.

Re: 1629's Tripple-shot from center zone in Autonomous.
 

You should probably read <G08> and <G09> unless your plan is to score for the opponent in Auto.

Re: 1629's Tripple-shot from center zone in Autonomous.
 

We were joking today about having auto mode start in the far field and kick 3 balls (which we can do), drive over the bump, kick two more in, for 5 points

Re: 1629's Tripple-shot from center zone in Autonomous.
 

Even being on the wrong side of the field during the video you would assume the same routine would work on their side.


Nice job Gaco, I can't wait to see you guys at chesapeake!

Re: 1629's Tripple-shot from center zone in Autonomous.
 

True. But I go by the saying "You play how you practice".

Re: 1629's Tripple-shot from center zone in Autonomous.
 

When we built our field we only had room for two goals. They just happen to be in the wrong corners for auto. There is nothing in the auto code that is side specific, so as long as the robot is pointing at the correct goal, it works.

Altough it was a problem for Aim High. :)

Re: 1629's Tripple-shot from center zone in Autonomous.
 

Now, the question: could you do that starting in the far zone and get 5 instead of 3?

Re: 1629's Tripple-shot from center zone in Autonomous.
 

Looks great! I can't wait to see it in action at both Chesapeake and Buckeye! I think you will find that our robot will nicely compliment what you guys do. Ours will do the back three while you are shooting the middle two!

See you all in a couple of weeks!

This is way cool. I wanted to do that. Awesome job, 1629.

Re: 1629's Tripple-shot from center zone in Autonomous.
 

It may just be our lighting, but we have trouble acquiring the target in the far zone. We will be able to just acquire the ball and kick, but without aiming.

I played with the targeting VI's, and was able to improve it a bit, but the target score just gets too low.

I also don't think we could keep full pressure for 5 kicks in 15 seconds. We need at least 60psi to retract the kicker, and they'd all need to be full power. :)

Re: 1629's Tripple-shot from center zone in Autonomous.
 

motor powered kicker....the only way to fly.... :)

Re: 1629's Tripple-shot from center zone in Autonomous.
 

How could you shoot three balls form the center when there should only be 2 balls? or do you have human players bring in balls form the ball returner?:confused:

Re: 1629's Tripple-shot from center zone in Autonomous.
 

Watch the video.

Re: 1629's Tripple-shot from center zone in Autonomous.
 

how consistent is your kicker?
our robot has been landing shots continuously from all zones, without a camera in autonomous mode...
as long as it had a "drive perfecly straight" code using some encoders on the wheels, it usually kicks straight as an arrow...

Re: 1629's Tripple-shot from center zone in Autonomous.
 

Our robot in autonomous is MONEY!

from all 3 zones :)

Re: 1629's Tripple-shot from center zone in Autonomous.
 

Show me the video.....

Re: 1629's Tripple-shot from center zone in Autonomous.
 

Talk's cheap... Show me the video..... (super :) )

Re: 1629's Tripple-shot from center zone in Autonomous.
 

Phil, for the issues with the target in the far zone, what image size are you using?

Re: 1629's Tripple-shot from center zone in Autonomous.
 

That video was legit. I like your robot as well. Where are you guys competing?

Re: 1629's Tripple-shot from center zone in Autonomous.
 

True. But not everyone goes by your saying either.

Good job 1629! I suspect many are planning to do this just in case their alliance partners cant. 5 would be impressive and common at CMP.

Re: 1629's Tripple-shot from center zone in Autonomous.
 

Just the default... 240x160 I think.

Target size was OK, but I just don't think there was enough contrast.

Re: 1629's Tripple-shot from center zone in Autonomous.
 

Chesapeake & Buckeye (Baltimore & Cleaveland)

Re: 1629's Tripple-shot from center zone in Autonomous.
 

It may be "money" from those zones but we can't get it to cross a berm and find the balls. Get your head out of the clouds dodar they one upped us there. ;) nice work guys.

Re: 1629's Tripple-shot from center zone in Autonomous.
 

You may need sleep, there is no 240x160 image size. Anyway, the reason I ask is that small images have bigger pixels which average over a bigger area. That means that automatically have a blurrier edge and a somewhat lower score. I think that the small image size works fine for close, but is difficult to work for third zone. Medium image works well for third zone, and you may be able to get small to work, but it is at a disadvantage.

Re: 1629's Tripple-shot from center zone in Autonomous.
 

Ain't that the truth! Anyway... It's the default that's used in the default program for vision tracking... 320x240 maybe...

On another topic... sorry to disrupt this thread....

We pass some status info back to the Driver Station to be displayed on the Cypress LEDs.

We've noticed a large delay in those status LEDs changing.

Eg: We have a "Compressor on " feedback light to indicate that the compressor has been "Enabled" by the operator.

The "Compressor On" status is simply the input (switch) bit echoed to the output (LED) bit inside the 100ms Periodic Loop.

In watching the I/O screen, and listening to the compressor we see a minimal delay between presing the Compressor On switch, seeing the DS Dig-In LED go on, and the compressor starting. However, there is an appreciable delay before the Robot returns a "Compressor On" feedback to the operator. It's not the Cypress because the DS I/O Screen Dig-Out LED shows the same delay.

The delay can be upwards of 2 seconds.

We can press and release the compressor ON button, hear the compressor start and stop, before the status LED changes. After about a second, we see the LED go on, and then off, so it seems like there is a message Queue that is full, and is taking about a second+ for any messages to pass through. (it takes me back to FTC Bluetooth issues)

This delay only seems to be related to uplink traffic, and based on the visual delay on the camera may also be effecting camera packets.

As far as I can see, Digital IO Output bits are sent with every uplink packet... so is there anything else that could be causing this lag?

Note: It happens even if we are running a BUILT program (not debugging)

How did it work at competition?

Re: 1629's Tripple-shot from center zone in Autonomous.
 

Which "it"?

Never got a chance to try the tripple shot. We were having trouble holding pressure for the pre-match waiting period, so we knew we wouldn't have time to get off all three shots. Also, the approach ramps to the the bumps were changing our up and over speed requirements so that didn't help.

Maybe in Cleveland this weekend.

As for the Driver station feedback... I don't think the kids look down enough during a real competition for it to matter too much :)

Re: 1629's Tripple-shot from center zone in Autonomous.
 

Yea, we had several different indicators on the classmate to show our drivers what was going on, but reality was, they became too focused on the field. So what did we do, cut or losses and forgot about it? Not quite, we actually are going to place LED's on the robot as specific indicators of what is going on with the robot. Hopefully this will trigger faster response from the drivers.

Next up, a full head's up display integrated into a pair of safety glasses. Should be interesting.

See you in Cleveland in a few days

Re: 1629's Tripple-shot from center zone in Autonomous.
 

I heard you were fielding a smaller team for Cleveland. Need any specific help? (eg: programming or electrical etc?)

Also, as the only two MD teams, there was talk of splitting scouting duties.... We should sit together in the stands.

Phil.

Re: 1629's Tripple-shot from center zone in Autonomous.
 

Yes we are only taking 15 or 16 students (I don't know the number), which is half of the amount we had at Chesapeake. Right now we are going to fix the few problems we found solutions to while home. As of now I do not think we will need any help, but may encounter some programming issues later in the day as we try to make improvements.

As for scouting, I believe the rumor is that we would like to have 3 students from each team scouting at a time. One team would have blue, and the other would have the red alliance. Locating close together would be smart, and ideally the same location as we were for Chesapeake. I can try to get some seats ASAP. I have never been to Buckeye before, so I am unaware of the format, but I am sure we can figure it out.
