This is a small project that I spent some time with during the second half of 2015. Now, after letting it rest for six months, I started looking into it again. The current setup is a SSC-32U that is remotely cotrolled from an Arduino (tested to operate with both push buttons and analog inputs from a joystick (my second Youtube clip).
The SSC was very powerful indeed but I am looking after less expensive solutions for theon board electronics. I have tested using an Adafruit servo control card and a Pro Trinket, both still fed by the onboard 6Vbattery package. The setup has been tested with some simple sketches to see that there is enough power to operate this configuration (no "brown outs" in the Trinket when the servos move). Well, it seems there is but in the process I damaged one of the legs.
Since it is damaged anyway I will probably move on with 3D printing new parts with better "looks" and higher precision. Don't expect too much to happen in the nearest future.
I also publish a small paper I wrote about the theory behind the robot. I soon realised that a key to success is to understand the maths and Inverse Kinematics behind and being a Mechanical Engineer I felt that this was one fun part of my project (beside cutting, gluing and coding). I have no code to publish (in fact there is plenty but I don't feel that any of it is mature enough).
