Xdozer

This robot can turn into a bulldozer!

Xdozer is a LEGO MINDSTORMS EV3 transformer robot. Thanks to a special mechanism, it can turn into a bulldozer or into a tracked humanoid robot in few seconds.

• In "vehicle" mode, the robot head and arms are hidden and folded, and the robot-in-disguise can follow dark lines on white surfaces. When it finds a red spot on the ground, the transformation into "robot" mode is triggered.
• In "robot" mode, it can drive around and avoid obstacles which it detects using the distance sensor embedded in its head. The EV3 Color Sensor becomes a chest-mounted laser cannon.

I designed this LEGO MINDSTORMS EV3 project using the parts from a single LEGO MINDSTORMS EV3 Education core set 45544. This EV3 project is ideal for classroom activities, especially to show students how to build a sturdy mechanism involving worm gear and parallelogram linkages. Furthermore, it's a sick LEGO transformer robot! Click the button below to get the building and programming instructions.
