Day 39: Week 6 Design Recap

 Day 39: Week 6 Design Recap

  • PM is nearing completion and should run on Thursday night.

  • Once PM is running we will quickly manufacture and assemble FM

    • Much of that can happen over the long weekend. Lots of assembly this weekend.

  • Auton is in a good place on AM

  • Drive practice begins soon

  • Now it’s time to find any and all ways that the robot can break or fail and fix them before competition season.

    • Also places that maintenance will be annoying and fix those too.

  • We are basically exactly where we were last year.


Day 38

 

Day 38: <3

More of PM was assembled today.



FM Drivetrain


Launcher

The launcher is complete and we added torsion springs to help balance it and remove some backlash. We also shimmed the gears today and removed a good amount of the backlash in the system.



PTFE Film

We put PTFE film on all the flat surfaces the note touches.

Day 37: Auton and PM Assembly

5 Note Auton

We were able to have our controls team work with the Alpha robot over the past few days. They were able to begin tuning in some of our auton paths. We successfully made a few 5-note autos. The launcher tilt on AM is inconsistent so we are most worried about our paths and intaking which is looking great.

PM Assembly and 

We’ve been able to get more of the practice machine assembled. It has all but 4 motors mounted (elevator, climber, and 2 launchers). The intake is fully mounted. The launcher and amptrap mechanisms are nearly complete. Climber still has a little ways to go but that’s always last.



Robot Weight

We weighed PM at the end of the night and got an approximate weight of our competition robot.

Day 35 & 36: PM Assembly

 3D printing

We have our print farm running a lot of production parts for the 3 robots (PM, FM, & Photon). Here are some of the timelapses from the Bambu X1C.

Laser Cutting

This is our laser cutting a test part of the launcher sector gear so we can test the fit. We manually adjusted the teeth size to remove some of the backlash in this gear.

CNC Router

It’s hard to get a good video through the chip curtains but this is our router cutting some of the climber+elevator gussets.

(It’s a loud video)

Tapping Station

This is a video I made a couple of weeks ago to show someone how the tapping station we purchased in the fall works. It’s pneumatically powered and has a lever to turn it on and a button for reverse. It has made tapping shafts so much faster and we’ve used that to design a lot of standoff into this year’s robot.

Test Fitting Controls

We started test-fitting our electronics layout. Our general plan is to leave as much of the belly pan open as possible for electronics and then just fit them where they make the most sense. Nearly everything is held down by VHB or foam mounting.

Day 34: More Trap Testing and PM Assembly

Trap Testing

We did some limited trap testing with a new hook geometry and bearing setup.

PM Assembly

We have begun rapidly assembling our practice robot. The intake plates, elevator, and main indexer+launcher pivot plate are mounted.




Intake Wedge printed in PCTG.


Day 33: Sponsors

We're incredibly thankful for the support from our sponsors. Their backing is essential to our continued success. This year, we're excited to team up with these fantastic companies and organizations:

Day 32: Week 5 Design Recap


Photon 8515

We haven’t talked about our sibling team much this year. 8515 Photon is our development team primarily constructed by students new to our program this year, mostly 9th and 10th graders. In previous years 8515 built an Everybot but we found the students weren’t learning to design and build in the same systems we use on the 3847 robots. This year we have decided to work on a custom design that shares a similar drive train and intake to 3847 but has a different superstructure. 8515 is building a similar archetype to several open alliance teams such as 2582 and 3467. 8515 will be competing at Katy and Houston district events this season.
