Lego walkers with 2 Legs are a challenge but this one runs. Today I am looking at a video about a biped robot with an interesting leg geometry that we can use in Lego walking robots.
My fastest and most stable Lego Technic Big Dog quadruped. This one also walks over uneven terrain. The leg stride is quite large for a quadruped. It keeps from dragging a leg by throwing both forward moving feet into the air on a bounce. This is my most compliant and efficient leg yet.

I lead you through programming a lego ev3 brick to have remote control steering with an IR transmitter. You need the steering to return to center automatically. If you are making a Lego car or drivable robot you might need to know how to program your lego EV3 brick to control a rack and pinion steering motor with the IR controller.

One of these Lego pullers spreads the input energy out more allowing for more energy to be imparted into a spring. I learned this from Battlebots years ago so I thought I would show it to you. It could be useful for a motor driven Lego gun.

Boogie down! Lego Technic robot Johnny is having a groovy retro roller-disco flashback. Watch his hips work it as he twists and turns on his path to a groovier dimension. A servo motor shifts his upper body and hips back and forth altering his balance allowing him to turn like a real roller skater. The hip/upper body motion moves his arms up and down. Two l-motors propel him with tank steering for additional agility, simulating the skater's legs pushing them forward and around in circles. These functions are programmed as sequences to an SBrick.
Check out Johnny's other adventures. Johnny has a motorcycle and he can ski. Watch his playlist here: https://www.youtube.com/playlist?list=PLMjP9Ps8jRD1XHrsT-dd2iz8kMFUC3Pp2
