Build the structure

This section focuses on building the base structure of the robot.

Structure and electronics


3d-printed parts

This robot uses 3d-printed parts to be easily remixed. Blender source files and STL are available at https://github.com/erdnaxe/kraby/tree/master/3d_parts or on Thingiverse.

This chassis also reuses the parts that come with Herkulex servomotors.

To build the robot, you will need to print:

  • 6x joint.stl: top part of one leg,

  • 6x foot.stl: bottom part of one leg, may be modified to adapt to different rubber endcap or touch sensor,

  • 1x box.stl: main body of the robot, may be modified to adapt to different electronics.

3D printed parts

If you are 3d-printing with a 0.2 layer height on a standard Cura profile, it should take around 22h30 of printing, and one quarter of a one-kilogram spool of plastic.
