Topic 1: Caleb’s transition

Topic 2: New Rules are out! 

  • Everyone please read through it, and encourage your sub-team members to read it as well
  • https://urc.marssociety.org/home/requirements-guidelines
    • Drone? (probably not, it's optional and no time)
    • Pointing out differences and anything new
  • PDR guidelines not updated for 2022
  • SAR guidelines not updated for 2022
  • Science Plan not updated for 2022

Topic 3: Bay Stuff (COVID Safety Guidelines, bay access, software tables)

Topic 4: Lance has left the team

      • Sent email to victoria for that
    • Get new shelving units, organizational things
    • Monies
      • Ask Farris about how much money it will cost
    • Ask Melvin about Antennas
    • Order USB 3.0 cable for gimbal
  • Mechanical 
    • Jasmine - Antenna
    • Ali - Science by himself (Maybe get more people on that)
    • Ethan - getting rid of design tasks to focus on lead stuff
      • End effector, issue with it being too loose
    • Medina 5/6
    • Austin 1/2
    • Mathieu 3/4
    • Need overall $18,000 distribution 
      • So mech knows how much money they can spend with the rover
    • Drivetrain, needs differential bar corrected
      • Emily might not want gears
      • Drivetrain is pretty strong
    • Two new members
      • Joe - looking into battery selection
    • Biggest problem so far, nothing is concrete yet
    • Motor selection
      • Anna buying a motor
      • Olabisi making motor mount
  • Electrical
    • figured out rough design of power architecture (next week/two working on PDB)
    • motor shortage with mechanical
      • 48V with drivetrain
      • 24V with arm
    • Science board (Chelsea)
    • PDB (Farris and Cindy)
    • BMS (Ari)
    • Gimbal/Arm 
      • unknown if a board is needed (probably just O-Drives)
      • Taylor's on gimbal
    • New members, no beginner friendly board
      • Have an experienced members guide them through something difficult
      • Can't really shadow PDB board design
    • Wiring up the claw
      • Mathieu I think wired the arm
        • Farris talk to Ethan and Mathieu about wiring the claw
          • Then, check with Orson and Cindy to see if testing on old drivetrain is okay
          • (this is so FW/SW can get started on testing)
    • ODrive firmware needs to be written (Aidan Gratton)

    • Get relationship with profs (Clare)
  • Business
    • Going through team's finances confirming all the orders that have been placed/how much has been taken out of the team/week account.
