How an ESP32 Turned a LEGO WALL-E Into a Real Working Robot
A maker has transformed a LEGO WALL-E into a functioning robot using an ESP32 microcontroller. The project involved replacing the static interior with motors and servos, allowing the robot to move and respond to a PlayStation 4 controller. Custom 3D-printed parts were created to facilitate the build, resulting in a WALL-E that behaves like the character from the movie.
- ▪The LEGO WALL-E was modified to include an ESP32 microcontroller for motion control.
- ▪Custom 3D-printed mounts and gears were designed to integrate hobby motors with LEGO.
- ▪The robot can be controlled via a PlayStation 4 controller using Bluetooth.

Maker Crostplay2 stuffed an entire robotics platform inside Pixar's tiny cleanup hero, and the result behaves more like the movie character than anyone would expect from a brick model.
