Work Completed

- added a pin to the cargo arm coupler in the hopes of stopping it from slipping -> cracked that coupler. Not sure how to resolve the slipping issue

- tested frisbee bot, it's in working order, should be good to play defense tomorrow

- had a pretty long discussion about buddy climbing. some conclusions:

  • if we want to double climb with a passive forklift that drops down from the front of the robot as we climb backwards, we need to shift our whole CG backwards
  • we need to focus on two things: saving weight in the front to allow us to add weight to the back (and also allow us to have enough weight for a forklift
  • moving the battery to the back of the bot should be pretty easy (Bob ordered wire to allow us to make this change)
  • we can put like 4lbs of steel in our back bumpers
  • we can replace the top lexan on the cargo intake with sheet metal

- painted some wood for FLL tables

- edited some work benches so we could have both a nice work surface and a place to store our totes. we will be able to store 6 totes under the whole table when we are done

- left coupler on climber kept uncoupling -> bob replaced one of the screws because it was stripped

- figured out why our robot cart clunks when we use it - one of the wheels has a flat side. ordered some new 4" wheels to replace robot cart wheels, and with that, it should be all good

 

Discussed pit options (none of this is final.  Nothing will prevent us from using existing pit layout and banners):

  1. Started reworking two small workbenches so they can be bolted together.  Discussed more rebuilding including removing 2x4 legs and replacing them with 2x2s and adding a second shelf to allow placing 6 totes underneath new combined workbench.
    1. Latest plan is to bring horizontal band saw for cutting tubing,etc. 
    2. Jig saw for cutting shapes
    3. Move Vise to new workbench
  2. For banners:
    1. Move large Ctrl-Z banner to front of pit using two new 2" PVC uprights.
      1. One upright will be zip-tied to shelf that holds scouting laptop.  (will require putting a heavy tote on bottom shelf)
      2. Move battery cart to a location under tall table that holds binders and handouts.  Charagers on top shelf of battery cart and batteries underneath.  Second upright gets ziptied to battery cart.
    2. Sponsor and blue banners will be attached to new 1.5" PVC that will attach to workbench.

 

 

Challenges

- Solo can't handle cutting a bolt

- we still don't actually know if a buddy climb is viable. lots of math left to do!

Work for Next Meeting

check the whiteboard! lots of non-robot tasks to do, such as....

  • pit improvement
  • design: buttons, keychains, posters (and then make them)
  • second coat of paint of the FLL tables
  • finish assembling the workbenches
    • add the 2x2 supports
    • remove the vertical bandsaw and swap it for the horizontal one
    • add the vice
  • Move a shelving unit, tall table and battery cart to garage and test proposed Ctrl-Z banner PVC to make sure nothing falls over.

 

  • write robot one-sheet
  • and if you're really and truly bored...clean. Boy do we need it. 

also robot work:

  • climber code
  • machine and attach the hatch hard stops (thanks Dina and Jonathan for finishing CAD and CAM!)
  • hack off the top of the hatch mechanism to save weight (hello windex 😄)
  • test and prep Poly for defense driving (it is driving slow right now, figure out why that is?)

On Schedule?

yes
