RBS

Action Items

• Ask Forrest to make 2 gears which mesh, and are both bolted to a perforated sheet of metal.
• Ask Forest to make up a set of pdf or SVG files I can use to make gears.
• Find a friendly laser cutter. I favor South End Boston Fab Lab because they can follow along.
• Make several hundred gears of all sizes.
• Make a 500 feet of plastic gridbeam using the CNC router at architecture.
• I want to move to an open source design system. I think blender is best because it is the open source modeling program with the most users and the biggest community.
• Prepare a proposal for the BRL-CAD people to design a gear-cad module for blender.
  • First, see what has been done with blender.

RepRap Building System

The 'RepRap Building System', aka 'RBS', aka 'Building System' is made from grid-beam type perforated beams, store-bought fasteners, and RepRap-printed parts like gears and fittings to hold stepper motors and smooth rods.

For more information, see TriLap.

RBS is a key element in the Education RepRap Education Initiative.

Description

• TriLap will be a steel square-tube CNC router made with tri-lapping joints, aka Tri-Joints with Image:NEED-trijoint example.jpg Note that this is slightly similar to LumenLab's RogR, but will be cross-fertile with RepRap.

We can if we want try to extend this use of gridbeam and erector-set like technology into a TriLap/Building_System system that levrages RepRap to make lots of mechatronic systems using grid beam and grid sheet, and 3D printed gears, etc., but that's sort of beyond the scope of this project. (Step 2, technically)
