Team 4329 is joining the Open alliance to add to the numerous teams going over their mechanisms and such.
We will be showcasing photos and videos on this thread to showcase some of the moments of our build season and how we are working out through this season.
We are going to compete at the Heartland Regional and the St. Louis Regional.
if you have any questions of this we can gladly ask and try our best to help out other teams and work with other teams in the ways we can.
starting off the thread are some quick montage videos to show a small amount of what we are doing, we will be posting more in depth mechs once we can.
This is a showcase of our intake and index/tower mechanism. We have a folding intake on this right now very similar to our last year’s intake with an over the top design with compliant wheels powered by a belt and 1 motor. Pictured in the back is our tower/index, featuring 3 belt systems, 1 in the front for intaking again, showing some complaints and mechaum wheels as well, and 2 in the tower pointing up to feed to an Armabot 240 Turret and our shooter which is not pictured here.
We have had a decent amountof success taking in 1 ball but with 2 side by side we have a problem with them jamming into our 1 intake system. No real ideas have come up to fix it other than just intake one. It’s going to be interesting to see what happens in case of a jam.
Other than that it works well and I’ll see if I can get some videos of it on the OpenAlliance discord and here.
some may be slightly out of date since some wheels were changed but the main idea of it is the same. We have success as long as all 3 motors for the tower are powered and it can fit 2 cargo snugly. a weird problem we came across was how we dont know how exactly to stop the cargo so they dont go up into our shooter, I believe we had some ideas to limit the power or to have a stopper but I have no big news on how we plan to do that so we dont have a cargo accidently in our shooter.
Featuring today we have our climber prototype finally starting to take shape. not shown here we will work with a piston which will launch a multistage climber up, which will be brought down by our winch system. The gear box for such is shown at the bottom
Our Intake had a change to it very recently, showcasing our mantis style intake. With a piston extended holding the intake up, and as it retracts the intake goes out, allowing for an easy movement directly on the intake
Shown here is our side view for our bot this year. Our intake now has 1/4in polycarb on it to increase its strength. We had our last polycarb intake at Cowtown Throwdown snap in half sowe we upgraded it with double the thickness.
Another view of our intake in use we found a new problem with our funnel system. When intaking two cargo they can sometimes get stuck, shown her is two cargo being brought up and 1 above the first, waiting for the blue cargo to go in and hopefully keeping the red one up.
Moving away from the intake our first piston powered climber came to being on our first robot frame from 2012. we have 1 arm prototyped to test out a piston and winch climber. no testing yet but we have good hopes
So people wanted to know more about our current climber so I will share this current design.
2 pneumatics lift up the climber and a gearbox located at the bottom winches a robot up. very similar to 95 and 3847s climbers this year but done with pneumatics and not springs, currently.
also featuring our data ranked by scoring and picklist scenario. our upper hub and multi level climb did not work so we placed 11th. we have work to do before STL but we tried what we could with what we had.
