Agenda

  • Review and discuss status of ongoing projects

  • Plan out and scope future EE tasks for end of comp

Ongoing Projects

  • Science board

    • Was assembled a while ago, need a status update on the firmware testing for the board

    • All board tests that could be completed without firmware have been completed

    • If firmware is completed, next test is to determine if rails are pulling correct voltages when receiving commands or signals (i.e. if its pulling enough voltage when powering a motor)

  • SPI LVDS

    • Either peripheral or host board is complete, however one is not complete yet

      • Taylor was previous contributor, may continue project, nobody actively working on it as its low priority

    • SPI LVDS

      • confirms SPI to longform signals, plan to use them on wrist and gripper joints as they are further away from odrives

      • not high priority as we can do joint by joint testing without converting to longform signals (just connect the odrive closer)

      • delegate tasks for receiving status updates

  • PDB

    • schematic is done and reviewed, layout in progress

    • layout will likely be done soon, however need to circle back to get a status update

    • parts have not been ordered yet

  • BMS

    • similar state to pdb, schematic close to competition, yet to be reviewed

    • parts have not been ordered yet - potentially part of the BOM

  • Multiphase buck

    • layout has been posted for review

    • ordering parts for the board soon

  • RS422 breakout board

    • RS422 breakout boards are completed and already mounted on the odrives

    • need to circle back with jason to see if there are any planned / future changes for the board

    • need to confirm current qty and how many we have working - will probably want to order more

    • M1 task to get full status update - see if they work, current quantities and design status

  • BLDC Motor Controller

    • it is likely no progress has been made for this yet; this would be a p1 task at best. very low priority at the moment

Future EE Tasks

  • Comms

    • M1 - need to find someone to work, learn about and right a nice operational confluence page on comms

    • M2 - latency and range testing after getting a core understanding of our comms system

    • M1 - confirm which antennae in the bay are being mounted on the drivetrain and where they are located

      • for M1 focus on picking anything that works then worry about improvements for M2

    • M2 - if there are any required changes to the base station, this needs to be determined (definitely more of a mechanical task)

  • P1 - if there is interest and manpower figure out how to make a battery

    • look for cost estimate, manufacturing process information

    • first need to refine power budget calculations through M1 testing before selecting cells

  • M2 - new members to get involved with testing and debugging for all M1 systems
