New - Spot Version 3 video and Interview for

Many thanks to Balazs from RacingBrick for testing Spot Version 3 and updating the Powered UP code to unlock additional functionality!

Spot Version 3 - In Action!

HUGE thank you to Balasz @ Racing Brick ( for helping me construct the Powered Up code and controller required to run Spot Version 3 - Powered UP!!!

See videos of walking and steering below:


Spot Version 3 - Powered UP!

Rebuilt Spot with Powered UP functions!

See pictures below of Spot Version 1 (Left) and Spot Version 3 (Right) for size, scale, and detail comparison.

As you can see, scale of the build has increased with the added functionality and is now close to 1:3 scale.

Overall, very impressed with the speed and performance of the new Powered UP motors to handle the added size and weight of Version 3. Building a new Powered Up App to control Version 3 however, has proven a bit more challenging than the build itself:)

Videos of Version 3 walking and steering coming soon!
