rautaIII

rautaIII is the third generation of the Rauta open-hardware robotics platform, designed for education, research, and rapid prototyping. It follows the earlier iterations rautaI and rautaII and emphasizes modularity, affordability, and community-driven development. The project targets users ranging from classrooms to university laboratories and independent makers who want a flexible, interoperable robotic base.

The hardware design centers on a modular chassis built from standard components, allowing users to mix locomotion options, sensing suites, and effectors. Core elements typically include a compact computing module, a real-time controller, and swappable peripheral slots for cameras, lidar, inertial measurement units, and grippers. The platform supports safe operation through features such as soft-start ramps, protective firmware limits, and an accessible emergency-stop mechanism, with power and protection designed for classroom and lab use.

Software and community access are a key focus. rautaIII runs on a Linux-based firmware stack and uses ROS 2 as its middleware, enabling straightforward integration of perception, planning, and control modules. The project provides an open-source software repository, application programming interfaces, and thorough documentation to encourage contributions, tutorials, and peer review. Programming support typically includes Python and C++ interfaces, along with examples for common robotics tasks.

Applications and reception have centered on education, hands-on research, and hobbyist experimentation. Users leverage rautaIII for autonomous navigation, manipulation experiments, and rapid prototyping of ideas, benefiting from its modularity and broad compatibility with standard hardware components.
