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.
