An open-source hardware enthusiast has shared their latest project, a 3D-printed, Arduino-powered Wall-E replica. This personal project, in development for over a year and a half, brings the iconic character to life with functional tracks, movable arms, hands, head, and sound capabilities.
Technical Overview
The robot is powered by two Arduino boards, controlling various mechanical and electronic components. It moves using tank-like tracks, though traction issues remain a challenge. Initially, it was controlled via a wireless PS2 module, but after damaging two modules, the creator switched to Bluetooth control via a smartphone, with future plans to integrate a PS4 controller or a better wireless module.
About 80% of the build is 3D printed, while the rest is made of wood, with TinkerCad and Fusion 360 used for modeling. The robot can move its arms, hands, and head, and even play sounds and music for added realism. However, the shoulders struggle with weight, and improvements are needed to refine motion and overall responsiveness.
Future Plans & Open-Source Possibilities
While the STL files are not yet publicly available, the creator is considering sharing them in the future along with proper documentation. They also suggest that enthusiasts can explore the Wall-E Builders Club for more resources.
This project showcases the potential of Arduino robotics and 3D printing in home-built animatronics. With continued improvements, it aims to become a highly interactive, remote-controlled Wall-E.
