Planet Explorer Rover – Otto Remix

This design reimagines Otto as a small planetary exploration rover. The robot keeps compatibility with the standard Otto electronics and servos, but the body has been redesigned with a rover-style chassis inspired by space exploration robots.

The model features a compact rover body, large rugged wheels for rough terrain, and space for additional exploration hardware such as solar panels. The goal was to create something that feels like a simple planetary rover while still using the familiar Otto system.

The design focuses on clean mechanical shapes that are easy to print while still looking like a space exploration robot. It can be used as a decorative rover build or as a starting point for a functional Otto robot with additional sensors and modules.
