[Processes Applied]:

  • Solid-works (Still new)
  • Laser Cutting (Cardboard) – Cheap and easy way of testing design before water-jetting it
  • Water-jetting
  • Lithium battery work – Soldering cells into larger packs (9S3P) (Lithium Battery Packs in multiple iterations, Currently on MK3 Battery Pack)
  • Lithium Battery Balancing
  • Motor mounting
  • Gear-sprocket assembly w/ chain tension-ing system
