Lego Technic Little Big Dog MOC is a walking robot that uses springs to store energy so it can spring forward with a galloping motion. I have made three videos before this of models that have legs. This is the first one to get all of its feet in the air at the same time. It's powered by SBrick.

2 speed automatic Lego transmission this time with rubber bands instead of springs. It's still super smooth shifting. The rubber bands and wheel/string arm make it way easier to get it to work.

A look at LEGO Technic battery weights and prices. Save money and have a smaller, lighter, custom rechargeable battery in your models. How to hook up inexpensive LIPOs from Amazon to your LEGO Technic IR receiver. I did not cover Buwizz because it is both expensive and is heavier than a naked battery.

These are my best Lego motorcycles in order of development.
1. Drift bike with rider. My first attempt at balancing with a riding robot.https://youtu.be/75nMmhfiKnQ
2. Self balancing with a steering driver. The driver steers by leaning and tilting the bike. 100% Lego.https://youtu.be/SOz37MJqyIk
3. Taking it to the next level with hobby RC gear! Fast and good control. Shocks on both wheels. Front ABS disc break.https://youtu.be/WK7cnZghk9w
