Basics

Semi-autonomous wheeled robot to help with various tasks around the workshop. Starting from the initial prototype of a non-propelled non-intelligent video recording workstation going to fully developed robot capable of repetitive tasks such as welding and working in tandem with humans.

Product Stages

Stage 1: Video Recording

edit

  • Raspberry Pi based video recording / instructional creation workstation.
  • Managed with PiNet.
  • 1 - 12V car battery to power the raspberry pi and the monitor.
  • Input / Controls:
    • Simple direct button controls that can be manipulated easily while wearing thick gloves.
    • Orbit / Scroll input to navigating in FreeCAD drawings.
  • Voice Activated Controls:
    • User can introduce themselves (to get attribution for instructional and fetch pre-defined task list / cut list / FreeCAD diagram).
    • Start / stop videos.
    • Ask to show specific freecad drawing.

Base 1 Free/TBD Recycled from an office chair. In Stage 4 the base will be replaced with a OSE propelled robotic base so it doesn't make sense to design/build one from scratch just for stages 1-3. If we can't find some old office chairs on craigslist, then this can be made very simply by just welding together a few angle iron pieces and attaching swivels wheels. Swivel wheels / casters can also be 3D printed if necessary (many options on thingverse).

Total: $324.47

Stage 2: Welding

edit

  • Add ReadyWelder / OSE equivalent.
  • Add 3 car batteries to power the DC welder.


Stage 3: Watch Me

  • Two cameras.
  • Computer Vision processing added.
  • Simple articulating camera arm replaced with basic robotic arm.
  • Shopaid can more intelligently record the user speaking into camera and the workarea / hand movements at the same time.
  • Robotic arms move to have one camera follow the users face and the other camera follows their hands.

Stage 4: Follow Me

  • Propelled Wheels
  • Shopaid can drive and navigate itself (be summoned from charging station to work area) avoiding obstacles.
  • Return itself to charging station.

Stage 5: Hold It

  • Robotic arms can be instructed to hold things in place: User would move the arm to desired position and tell robot to lock in place.

Stage 6: Repeat

Stage 7: Clean

  • Put away all tools and clean the shop. Awww yeah!
