Description

* Based on Kinematics article from Steve Graves:
* http://fab.cba.mit.edu/classes/863.15/section.CBA/people/Spielberg/Rostock_Delta_Kinematics_3.pdf
* And an adaptation of the linear servo's from Massimiliano d'amario:

Details

This is the first attempt to use 3D printed servo's for a Delta robot.

I am now working on the Arduino software...

Deltagear.stl This gear has to be printed 3 times. It fits exactly over one of the standard horns. Please cut of exess of the horns! - 37.00 bytes - 03/05/2017 at 15:04		Download
Deltatriangle top1.stl This part to be printed once; it is the top of the unit. - 55.00 bytes - 03/05/2017 at 15:04		Download
deltabeam.stl This part to be printed 3 times. It may be necessary to sand in order to fit smoothly in the Deltatriangle parts. - 37.00 bytes - 03/05/2017 at 15:04		Download
Deltatriangle bottom1.stl This part to be printed once. It is the bottom part of the unit. The wires coming from the servo's should be put through the holes. - 61.00 bytes - 03/05/2017 at 15:04		Download

Step 1

Print the .stl files preferrably without brims, they are difficult to remove. It may be necessary to sand the beams in order to fit.
Please inform me if the .stl files are not in the correct size....
When constructing, set the servo's in the middle position, set the beams in the middle position and then fix the gears in their middle position.
