nice. I like the intakes, but I question if they have any benefits over well tuned flaps, because with normal, non-ratcheted intakes it’s definitely possible to intake and descore fluidly and quickly without needing to actively open and close the intakes. Also, the ratchets on your intakes look like they would cause significant power losses at those high speeds. and it looks like you might have to open and close the intakes each time you want to descore, which would make it slower. (I’m just assuming this, could be wrong)

Strange how we go weeks without a reveal and how multiple are posted a day randomly. Also will worlds really happen and if not then you won’t be going. Or will corona virus still be a pandemic and Texas will be Texas making worlds happen.

Also cool bot but wondering if you can do middle tower

I don’t think that rubber band intakes are inherently better than flaps, but the reasoning behind the acutated intakes was actually for programming skills. Normally, the intakes would have to be very in line with the ball to intake well, but the actuation means that the robot can be off by a bit and still intake the ball.

Maybe, but not as far as I’ve seen. Just bearings and lubricant.

This is possible with this robot, but not always the case. For example, at 0:26 you can see two balls being descored without opening the intakes.

Not random, but maybe arbitrary.

I…don’t know…

We can both score and descore from the center goal.

by well tuned flaps, I was trying to say standard intakes (non-actuating) idk why I called them flaps.
I can see how your intakes would help with consistency in programming, giving you a huge margin of error, but I think that well tuned normal intakes have plenty of wiggle room. for mine at least I can be off by a couple inches in either direction and still intake the ball just fine. but I can see field setup variances and drift causing issues for prog skills, so actuating intakes could be a good solution to that.

Exactly what we had in mind, thanks!

I’m sure, though, that with very acurate field control/aligning, you could make non-actuated intakes work well for programming skills.

x drive, actuated intakes, and odometry. this robot is ideal for programming skills, nice job!

Thanks! That’s nice to hear from someone who had such a good programming run in TT :grin:

Did you specifically make this robot for skills autonomous. It kind of sounds and looks like it. Nice job by the way.

Robot looks great! The actuated intakes seem like they’d be awesome for programming. Seems like this weekend is a great time to upload reveals!

Yes, in that we identified programming skills as the most important component to winning skills at events during this season, but of course this robot can still be competitive in match play. It just has several features which make it effective at programming.

Thanks!

Yes it is! :wink:

Really like the actuated intakes and the X, both could be huge advantages in terms of programming skills.

The actuated intakes are synonymous with the angled intakes from tower takeover in that they significantly increase the margin of error of the intakes. In fact, I think these actuated intakes increase the margin of error to be greater than the entire width of the robot. Really innovative solution, nice job!

Very nice. Definitely among the top 5 bots i’ve seen this year

I agree that margin of error in intakes is something many people are overlooking this year. cycle time is valuable, but not as valuable as being able to pick up balls super quickly imo. Ive been thinking of ways to have a super wide margin of error in intakes while also having enough compression to descore, and this is certainly a good way to do that!
looks like tennessee’s in for some good matches early season🙂

Thank you! They do act a lot like angled TT intakes in that regard.
