2021-12-31 - Mech Leads Meeting

Next Mechanical Meeting: Jan 4th Meeting, 2pm

  • Returning members

  • New machinists welcome

Goals

  • Review overall mech goals

  • Review member engagement

    • Intimidating when there's nothing easy to start with (nothing delegated, nothing to help them get to know the rover)

    • Good to reinforce the importance of small tasks

    • Make active efforts to ask if people know what we're talking about

    • Good to include educational bits in meetings! Makes it worth it

    • Big wins when everyone knows what's discussed

    • Keep in mind small design tasks! → bounty channel!

  • Review meeting structure

    • Tech topics! → not every meeting, but down

    • General mechanical meetings

    • Design review meetings should be separate from update meetings
