What we don't know/need to do

  • All the math and physics to make this all possible.
  • Linux management and networking knowledge
  • Kubernetes or k3s
  • Building container images and pushing/hosting them internally
    • Local container image caching, kube-fledged ( would be interesting to see if the nodes sync the cache directory )
  • Source control and test/builder runners
  • Design and calculator actuators/servos for specific needs/demands

Checklist

  • Something about MVP with actuators? having simpler 3D printed design?
  • Find forces needed to support/lift backpack of a certain weight if lifting vertically and rotationally at different overhangs
    • Determine max acceleration limits in relation to CG overhang and max torsion Nm for comport.
    • Investigate movement patterns that reduce torsional forces on the wearers back.
  • Determine weight ranges and rotational/movement forces and how those feel in a backpack configuration. What is the maximum rotation speed for torsion felt and comfort? Could use motion/movement to reduce torsion forces on the back. Bring weight to center of axis before rotation.
  • Determine style of actuator to use and with ease of customization and manufacturing
    • Cycloidal drive ( seems the most approachable/customize-able )
      • May be able to stack frameless motors on a shaft for a through-hole for attachment mechanism and other electronics pass through and making a multi-stacked-actuator. ( two required for sliding up/down the backpack and rotation )
    • Harmonic
    • Sun gear
  • Determine basic layout/space needed for motors and controllers
    • Use information to determine range/size of motor components and weight added.
  • Think about haptic feedback for wearer and conformability in donning backpack.
    • Balloon sacks in locations, vibration motors?
    • Other means of feedback? sound? touch? lights?
    • Robotic systems should alert the user to movement to avoid issues with not bracing for a movement
  • Backpack sensors and systems
    • Handle/Grid sensor to detect handing for potential detaching procedure.
  • Kickstand/method to allow the backpack to be serviceable or openable. how does it sit? Can it move/rotate while sitting? Can it prevent itself from falling over while sitting. Can we add an attachment to allow to to roll around/move? Light a mechanum base? Can it turn into a robot?
  • Physics and control of backpack rotation and gravity compensation
    • automatic characteristics of the backpacks motion in different scenarios
    • Should it have a personality?
    • How to avoid movement that may hurt the wearer?
    • How to move to aid the wearer?
    • Can it be used to prevent accidents like falls?
    • Can it aid the wearer while walking/running?
