LAVA R3X

Lava R3x is a humanoid robot that shuffles along the ground (similar to Alpha Rex from NXT). It is featured in the LEGO MINDSTORMS EV3 Discovery Book. I made a few modifications as showing the pictures. Not hard to build or program, just time consuming. I attached a USB light to the USB port on the robot.

I removed the moving head and arm mechanism in favour of being able to prop my iPhone behind the EV3 Brick, and used velcro zip ties (yes, they exist) to hold it in place. The infra red sensor is connected with these pieces:

I replaced the 2x4 90º angled beam at the back of the foot with a 3x5 ones. It now walks slightly better.

Completed to Exact Instructions:

“Figure 19-1. LAVA R3X walks around on two legs while moving its head and arms, and it greets you when you shake its hand.”
