Action Items

David ChoiRedesigning shovel to be two claws

Science:

  • Continue shovel redesign

E-box:

  • Integrate new PCBs, connectors, Does the e-box need to be made out of metal? Can we save weight by making it acrylic?
  • Simulate cooling (liquid? Air? heatsinks?) for power distribution board
Cole Myers


  • Talk to Missouri about gimbal
  • Betaflight
  • Talk to Lance about drones

New Tasks

  • Arm
  • Motor controllers
  • Localization
  • Science

General Notes

  • Bay closed for foreseeable future due to COVID
  • Want to start using ANSYS and SW PDM

Planned Projects

  • Continuing science module development (probably most important)
  • 3 D.O.F., continuous pan, self-stabilizing gimbal (generic cool mech project)
  • Replacing 12v DC with 24v DC (possibly brushless) motors (reserved for masochists)
  • Sexy wire, control and driver PCB management (mech x ee = best ship)
  • Fixing base station (bringing big guns with FEA)
  • Robot Arm mods (camera mounting, modeling backlash / make unified calc)
  • New drivetrain

 Science

  • Sealing mechanism currently unreliable (not properly tested)
  • Hooks for lifting seal cause binding because they only lift from one side
  • Elevator currently doesn’t go down all the way (due to CAD oversight)
  • Shovel being redesigned to be two claws (David Choi)
  • Indexing limit switches are kinda sketchy (but may be due to print quality)
  • Elevator limit switches don’t always contact properly
  • Elevator CF spring might not be necessary?
  • Probably want to switch motors to brushless

Gimbal

  • Missouri has it, ask them how theirs work?
  • Betaflight - Cole Myers
  • Pixhawk
  • Cole to talk to Lance offline about drones :)

Replace 12V motors with 24V motors

  • Maybe brushless?
  • Spec 24V motors and integrate them into our robot

New drivetrain

  • Carbon fiber 
  • BLDC motors
  • Lighter
