My Name is Marcus Knowles and I am a manufacturing teacher at Arts and Technology High School in Marysville, WA. Our class is called Penguin Manufacturing and this is a lesson I teach in our robotics class. Our advanced manufacturing students help make the parts and kits for that class. We are working to create kits to sell and use as a fundraiser for our program. The kits will end up costing about $13 and we may get a Kickstarter campaign going to help with some supplies. I will update the Instructable if that happens.
There are many improvement ideas and we would love to hear your ideas and changes to this plan. Current research and development includes possible injection molded parts and 3 arms on the armature. We have prototypes that have been made on our MakerBot 3D printer, and CNC router but the Kickstarter would help pay for an injection molder or Laser cutter.
The current tools needed to make the parts are:
Engine Lathe (not needed to drill the holes in the dowels, but we have one, so it is easy)
Misc. hand tools
