Day 37 – Bumpers and Bumper Usage (2/09/2020)

Driver’s Test

Today, we had the Driver’s Test. The driver’s test consists of two parts: a written, multiple choice test focused on the rules in the game manual, team updates since kickoff, and important Q&A questions; and a driving test, which involves precisely following an intricate path around a series of cones. 

Through testing, we were able to narrow down candidates for each of the drive team positions. The selections will be made and released after our week zero event. Thank you to everyone who showed up to the driver’s test!

We are still waiting on most of our parts to come back from CEM/arrive in the mail, so we continued to assemble bumpers. Yesterday, we completed the practice bot bumper set (except for fabric and numbers).

Today, we completed 

  • Plywood backing for the remaining two (red + blue) bumper sets, including the necessary bearing pockets
    • We found that the bumpers are flexible enough to only necessitate a small 2” diameter pocket over the location of the bearing. Instead of making a gigantic pocket along the entire length of the bumper, we can instead just flex the ends of the bumper out while pushing it in. 
  • Cutting most of the pool noodles for the remaining bumper sets (we ran out)
  • Taping pool noodles to one set of competition bumpers

We are still waiting for

  • Fabric + numbers to arrive in the mail
  • A horizontal bandsaw blade to cut the brackets that mount the bumpers to the robot. Unfortunately, the aluminum-cutting blade that was in the saw broke while someone was cutting steel.
  • More pool noodles

Active Intake

Today, we mounted the airpod/cleaver structures onto the robot. We are still waiting for a lot of parts to come in the mail, such as

  • 1.5” OD, 1” ID rubber tubing
  • 1” OD metal pipe
  • VersaPlanetaries 
  • Belts
  • Belt pulleys
  • etc

These COTS (commercial off-the-shelf) parts will make the intake assembly look more like the CAD.
