R2-IQ: 2-3-2

Build Day 20:

One of my favorite parts of this build will be R2's ability to transform between 2 legs and 3 legs and back to 2 legs.  It will not be done with actuators in the shoulders, but by using the motors in the feet.

Here are a couple pictures from my first test.  In this prototype, the third leg can not raise up into the body, but it will in the final version.

The video shows my first trial run, switching from 2-3-2.  Right now, the shoulders are not very sturdy, and I'll need some work around how the legs move...  but it's a start.
