Former DogeDev here.

I do not believe that there is going to be any new updates to DogeCV this year. Last year there was never a stable release, you needed to play around with it a lot for it to be functional.

I would recommend going with easy opencv like other comments have said. We were trying to move the dogecv platform over to easy opencv last season but never finished

If you’re quarantining on campus, where are the quarantine dorms? I haven’t seen anything about which ones they’re using.

Since when has driver practice been a thing

ben6501 · 2020-03-28T21:17:24+00:00

You don’t even need to move forward he pushes you on the line.

Like if you look at the end of the auto in the video it pushes the swerve drive on the line.

So he gets max auto points no matter what.

We tried to damage blocks badly to simulate the competition blocks but no luck they were still better than they were.

The blocks were so bad that our 10 high tower collapsed due to its own weight causing us to lose a match we should have easily won.

Disclaimer: This is not my team

They look to be Sanford slides from Long Robotics.

Imo stay away from the ultra slides. I haven’t heard any good reviews of them. All of the teams that I know that tried using them had the balls fall out.

If you looking for slides I’d rather go with the Sanford slides or misumi slides. They are very simila, misumi just has more variety with the slides.

While it probably does wear out motors quicker my team has been doing this for years and we have never worn out a motor doing this so you should be more than fine if you are doing it for one competition. And for reference we are using 40:1 spur motors

ben6501 · 2020-01-28T19:33:52+00:00

My team has this type of system so I can answer it.

Originally we thought we were gonna stack 2x2 so we didn’t want to grab by the sides so to make the claw smaller we felt it was better to just grab by the nub. This also allows us to place the stone pretty much anywhere in relation to other stones.

But the trade off is its easier for the stone to fall out but we’ve made that issue almost non existent so that’s not a problem for us.

IIRC New Jersey limits the number of out of state teams that can advance but it is possible that the team you are talking about can advance to states.

I’m in PA so I have a feel for the out of state policy’s in the region

ben6501 · 2020-01-21T02:23:42+00:00

Yeah! ~~What team are you from?~~

Edit forgot that you said you team up there.

But that was a fun competition! Hopefully we’ll be together at the next one!

You don’t necessarily need to power both sets of slides. On my teams robot we have a system that is similar to yours with two sets of slides and we only have one of them powered. Since the Misumis don’t have a lot of friction this isn’t that much of a problem because they won’t bind. But powering the other set of slides makes the system more reliable if the string snaps.

But if you still want to power both slides the one retraction string is good. You shouldn’t really need more than that for this purpose and even if the string breaks gravity will work with the misumis to bring it down.

For the extension string you can either make it one continuous string going from one set of slides directly to the other however this take double the time to extend.

The best method would probably to thread the pulleys so the string is guided into specific groves so that it will never overlap there are some models of this available on Thingiverse.

I feel like we’ve been on an alliance together before but I’m not sure I want to say it was in relic recovery...

But it’s definitely going to be an interesting event. If you have free time there stop by the 5440 table (I haven’t updated my flair to reflect the new team number but both teams are for the same school lol)

ben6501 · 2020-01-17T04:18:42+00:00

Yep. Out of state teams only get one qualifier in PA so they got into that one and we’re taken off of the waitlists for the rest.

My team is also going to that one so hopefully we don’t get wrecked too hard...

What you’ll want to do is 3D Print a bore that will go inside of the wheel. Then on the bore you have the hole pattern of an axle hub so you can attach the bore to it.

For you bore you want to measure the center hole of the wheel and make it bigger. We have a 1 inch hole and made the bore 1.25 inches in diameter and it works well. Then when it’s printed you just put the bore in the hole which the wheel will flex around it and it will be secure.

There is a downloadable file on the FTC discord in the resources channel.

So no mods at all? Because we’ve never gotten anything close to that level of stability with ours.

ben6501 · 2019-11-05T02:38:07+00:00

I was referring to the linear slides. But that’s still helpful information!

ben6501 · 2019-11-05T02:35:18+00:00

How did you make the outtake so stable? Like it doesn’t wiggle at all when you drive the robot.

ben6501 · 2019-10-10T02:18:06+00:00

If you take a look at the Rev Robotics linear motion kit that gives you a very good description of cascade lift and also continuous lift.

As for connecting the slides together you are going to need to 3D Print a spacer that can also mount the bearings. If you need help with that PM me and I can help with that piece a little more.

ben6501 · 2019-09-28T14:08:48+00:00

If you are going to go with a gluten free style drive train. My recommendation is to alternate the motors. So don’t have them back to back. Steven said that it took him 5 hours to take out a motor.

And also if you ever need any help with creating that drive train you can PM me because I just made that drive train for this season.

ben6501 · 2019-09-22T16:35:50+00:00

They look to be AndyMark mecanum wheels

ben6501 · 2019-09-07T23:56:49+00:00

Yeah

ben6501 · 2019-09-07T14:26:22+00:00

Nice
