Action Items

David Choi

Redesigning 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
