Working on the body design

Yesterday I spend sometime at my local #fablab  #fablabnordvest learning to know their Chinese Laser cutter. I used 4mm. white acrylic.

The design was made with #iDraw and exported to SVG (You can download the SVG here Body.svg). But my Chinese friend only speaks DXF or AI. After importing the converted AI file, I realised that I needed to do some cleanup of the path. Some of the patterns appeared twice(?).

Anyhow, it’s always mesmerising to watch a machine do it’s work.

After playing with the assembly, I want to redesign the way the lid is attached and I will like to make a   smaller version for 9g servos. Probably the easiest way to do this is to use OpenSCAD to create a parametric model with the size of the servos as a dynamic variable, and then create a projection which I can export to DXF.


Build and test of the new design

Today I finished the new design for the body. I began to use iDraw for this project, and until now it has been a very positive aquaintance. I used to be a competent Illustrator user, but jumped of the Adobe wagon some years ago. iDraw fells very familiar and stay out off my way.

You can download the pattern here: FelixBodyPattern.svg

To test the dimensions and the range of movements, I cut the pieces from 4mm plywood using the pattern as a template, then put it all together using bolts and washers.The servos are fastened with 3mm. bolts and the knee with 2mm. Below you can se af video of the assembly process.
