You moved your head! Does that make you ‘appy?!

Hector’s arm moving!

The arm moves.
It is going slowly as I didn’t put all of the screws in yet!

Updated Thingiverse

I have spend a considerable amount of time arranging the STL files onto thingiverse.
As Thingiverse has no concept of revisioning or assemblies, these are in several links.

The master link and all of the STL files for every part are now on

Nearly printed upper robot!

So Close! Finally printed the left shoulder and upper arm joints. All of these are calibrated too, so I can move them about. Will post vids at some point.
I am not happy with the neck assembly. The connection to the torso is a little too flimsy for my liking. Also the servo in the neck is almost impossible to mount.



Hector Left arm!

Hector now has a left arm.

Here are the pictures after printing and before assembly.

I have been hard at work designing a waist and waist rotation mechanism. It is starting to come together!
