This year, we are showcasing 8059A, 8059Y and 8059S.
As usual, do feel free to post your questions and I will relay the questions to my students.
What to look out for:
Our Standoff-linkage DR4B used by 8059A and 8059Y.
We first used this version of DR4B back in 2018 worlds (ITZ season), but somehow it went under the radar.
A lighter and faster version of DR4B. So do check it out.
8059S - And as in previous years, here’s our version of “herobot”. It was by our 1st time teams made up of 12, turning 13yo members.
We taught them how to do drivetrain and 6-bar, and the rest were up to them to figure it out (including the toggler).
Simple design, but enough to do the basic and get the new teams excited.
Hmm… take a look at where the motors for the DR4B are mounted, and you will see the difference,
The motors for DB4B are normally mounted in between the 2 sets of 4-bar.
But for this case, the motors are mounted at the bottom of the lower set of 4-bar and standoff are used to push up the upper 4-bar.
Short answer: it’s an intake chamber mounted to a 5.5w motor to rotate.
A slightly longer answer: The intake is just mounted via a low strength shaft to a 5.5W motor and rotation sensor, the programmer mapped the rotation sensor on the dr4b to the rotation sensor on the intake, allowing us to update the intake position as the dr4b went up. As for the color sort… it wasn’t tuned properly so we didn’t use it in matches (but it will be done eventually).
Is there an explanation of this anywhere? It’s a super interesting mechanism, but the most content with it that I could find were the override reveal and itz worlds reveal, which weren’t very helpful.
I will see if my students are able to do a short explanation video of it.
But basically, by shifting the motors from in between the 2 sets of 4-bar down to the bottom of the lower 4-bar, it will make the entire mechanism (ie. DR4B) much lighter.
The usual DR4B will need to carry the motors weight up and down (when lifting), but for this method of standoff-linkage, there is no need to do that.
The motors will just power and lift the bottom set of 4-bar, and the standoff will push the upper set of 4-bar up.
You won’t be able to find much content about this. Coz from what I know, even back in ITZ worlds, there wasn’t much attention to this approach.
