179 Hurdling video

[Swampdude]

Here it is (http://www.179swampthing.org/videos/2008/179%20Hurdling.wmv) - The battery was pretty dead, but I think you can see in this video, chassis speed is not very important. There's a number of control changes to be made which will speed this process up, but he's doing good.

I counted 5 hurdles in 2min (not counting knocking the TB down). Very nice. This should be around the bench-mark for most efficient hurdlers. Can't wait to see you guys in Florida:cool:

[Sunshine]

Nice job.
Great concept
Picks up the ball quick
What's your speed around the track?

[technoL]

Nicely done. Can't wait to see it at UCF!

[paulgerr]

Amazing design there. The speed at which it gets the ball over is fantastic.

Just curious though, how efficient is it at getting the ball off the overpass initially (either in Hybrid mode or Player-Controlled mode)?

Thanks, Well the bot can go 10.5, but he's running about 3/4 speed there I guess. The battery was dead, and he doesn't punch it on the straights. Our field perimeters are inset 2' on the sides and 5' on the ends. But the barrier is full length. There's just not enough room to go faster than 10'/s from what I'm seeing.

on a scale of 1-awesome it's pretty awesome:yikes: well done, looking forward to ucf

[s_forbes]

Very cool! Be sure to watch the contact on the downside of the hurdle; I think some of those may not have counted during a real competition.

Well i guess we are all set then (=


great machine, it really does look like a swamp thing. You sure do have a lot of steps to hurdling.

[R.C.]

so your using a ram to lift the ball up and down, probably a 2inch bore ram with 12 inches of stroke. Also we are using the wheels as a grabber also

I'm having trouble getting the video to play, but would very much like to see it. Any chance of cross-posting it to youtube?

Another quality machine from swampthing, congrats guys. Can't wait for the Florida regional.

I always love 179's robots year after year. I was expecting an arm design similar to your 2004 robot, and a speed faster than 2005 swampthing. I must say your hurdler is very effective, and it is excellent your team is able to do driver practice for another week. Have they been able to put the ball up on the overpass yet for 12 points? How long does it take them to do it?

[neoshaakti]

nice machine. How exactly are u projecting the ball over the overpass? are you just using the wheels to propel it outward? I couldnt really see the back of the claw at work

- Hi Barry,
Yep we've set balls up there, also caught them if pushed off to do the "maintain posession" thing. It basically takes just as long to set it as it does to keep pushing it over. Actually the way its doing it now is not going to be the final method :D But this is good training and demonstrates to others what arm hurdling will probably look like. I think we're going to speed this up to get maybe 1 or 2 more hurdles in in a 2 minute period, unencumbered that is....

- I don't have a youtube account, are you still having a problem viewing it?

- right now the wheel is just rolling the ball up and the arm pushes it the rest of the way. Later we will hold the ball at a higher elevation and thump it against the overpass at speed to bounce it over.

- I see that some of those didn't count, which is nice to have a week of drive practice.

I can see it now... thanks! I don't know whether it was something changing on your end, or just using the Windows 2000 at school rather than Vista at home, but very impressive.

On a scale from one to high quality I'm going to give this robot a pretty flippin high quality.

Thanks Dan,

Is there a remote chance you guys could come down to our little scrimmage this weekend (Saturday)? I know you guys usually do your own up there.

Also, who is planning on coming? I know 1251 and 1345 are not planning to. 180 might and usually MARS is dependable, but can't confirm yet.
1029?
710?
744?
1889?
108?
168?
59?

who else?

MARS definately will be there. Swamp's robot looks mega-awesome! Wish we were as far along; we're still tweaking a lot of things & drove it for the 1st time yesterday.

[Ericgehrken]

Another amazing swamp bot, can't wait to see you down at championships.

[Dan Richardson]

Thanks Dan,

Yeah, I actually can't speak for the team, I don't really organize that kind of stuff anymore but I believe we are supposed to be heading to the Robot Ruckus or something like that. It will be good for us to stay close to home, still got a fair amount to work to do, and the programmers are now trying to transfer our hybrid mode to the new bot.

I can't wait to see video's tho, most of those teams are usually major players at UCF and quite often in Atlanta as well. Your scrimmage seems to set the tone for what to expect at Florida.

I wish we could go, but we are still behind schedule and one more Saturday of building is needed.

Great robot, very simple and effective. It will definitely be a strong robot in the season. Very good use of pneumatics. :rolleyes:


See you guys in UCF

[Michael Corsetto]

Very simple and effective, picks up the trackball ridiculously easily. The arm seems very efficient and robust. Looks like a quick and reliable robot from 179, as always. Thanks for posting the video.

Any video of the scrim today I'm anxious to see.

I don't think anybody made one from the scrim, but here's one (http://www.179swampthing.org/videos/2008/179_2008.wmv) from the last few days :)

[Swampdude]

And here's a couple autonomous runs (http://www.179swampthing.org/videos/2008/179_Autonomous.wmv)

[Dan Richardson]

Man that thing is a beauty, It looks like you've got some sort of feedback finding the ball, you have Ir or Sonar or something to detect the ball? And it looks like your drivers are getting really good, that is really a smooth intake system and good method of hurdling.

I'm hoping we can get some vids of ours soon, the programmers have been working hard on something special for this year.

[Maggie27]

Great idea & works pretty well. ((Love the green))
Good luck at the competitions! [:
I'd like to hear how you do.

[Swampdude]

Well it's a combination of tooth sensors, gyro and I/R. It knows it's starting position, then it's told by the robocoach what position the ball is in after it gets going. Our field is short so it keeps hitting the wall after the turn, but on a full size field it should make the turn, and maybe go for another 4pts after that.
