With enough motors and brackets to build a second leg, the hardware build continues! I have spray-painted all the metal brackets to go with an all-blue colour scheme. The Robotis plastic brackets were hard to source online, so I got them printed by Shapeways.

I re-purposed the test rig frame used for the single leg to make a platform for the two legs. It’s made out of MakerBeam XL aluminium profiles which are very easy to change around and customise to any shape. This base will work well until I get the rest of the plastic parts 3D printed and the metal parts cut.

I also had enough parts and motors to assemble the 2-axis “spine”, but the main frame is not yet built so it that part is on the side for now.

Here are a few photos of the build:

In the next post I will concentrate on software updates to the leg and spine kinematics.
