Challenge: Design several simple 2D models of square tubes. We will laser-cut these designs out of card stock, fold them into 3D tubes and use them to assemble a scale model of OSE's tractor.
 
Skill Requirements: Beginner or intermediate designer
 
Equipment Requirements: Any 2D vector design program, such as Inkscape, Illustrator or Corel Draw. OpenSCAD also a good option.
 
Context: We are looking to incorporate rapid prototyped scale models into our development and prototyping process. In the case of the OSE tractor, this requires a series of square tubes. We've attempted to 3D print scale versions of these tubes, but found out that it takes too long. Therefore, we are now turning to laser cut parts and  asking beginner to intermediate designers to help us create the flat designs - which we'll cut out of card stock and fold into 3D shapes.

Intro

This is a running list of Test-Driven Design, rapid prototyping, and larger prototyping tasks required for the completion of the GVCS. English Translation: This is a list of important tasks that need to be done to deliver the promise of a life-size LEGO set of powerful production tools and machines.

List

  1. Power Cube Scalability - quick connects for structural mounting of one Power Cube upon another. For this, it may be useful to use the Bobcat Quick Attach between cubes - but the Bobcat Standard Quick Attach strength specification may not allow 10,000 lb or more types of forces required of stiff attachment of power cubes to one another if they are used as structural attachments to further modules - such as another implement mounted on the Power Cube. There needs to be a solution for a heavier duty quick attach which can be used as structural mounting that constitutes heavy equipment frames.
  2. Backhoe pivot - http://opensourceecology.dozuki.com/c/Pivot - the backhoe pivot is complicated - and we believe it could be simpler - such as returning to the chain version of turning. See Backhoe Pivot with Chain.
