**London, UK** – Canonical, the company behind Ubuntu, has demonstrated a new method for updating the firmware of the popular TurtleBot3 robot using snaps. This innovative approach leverages the power of snap technology to provide remote, automated firmware updates, ensuring seamless operation and compatibility with the latest ROS distributions.

The TurtleBot3, a widely used robotic platform in the ROS community, incorporates a Raspberry Pi 4 running Ubuntu and ROS, alongside an OpenCR board that interfaces with the robot’s motors, IMU, and battery. However, the OpenCR board’s firmware requires manual updates to match the ROS distribution, potentially leading to compatibility issues.

Canonical’s solution addresses this challenge by packaging the OpenCR firmware update tools and binaries into a snap, enabling automatic updates. This ensures the firmware remains synchronized with the ROS distribution, eliminating compatibility headaches.

“Snaps provide a powerful way to manage and update software, and we’re excited to apply this to the robotics world,” said a Canonical spokesperson. “By leveraging snaps for firmware updates, we can ensure that robots remain up-to-date and operational, even without a physical connection.”

The solution involves a custom snap application that downloads and flashes the firmware, while snap hooks ensure the update occurs seamlessly during installation or refresh. The snap also incorporates a configuration option allowing users to disable automatic firmware updates for specific scenarios.

“This approach has the potential to revolutionize how robots are maintained and updated,” the spokesperson added. “It offers a convenient and reliable way to keep robots running smoothly, even in remote or challenging environments.”

Canonical plans to further explore and improve this approach, including incorporating backup strategies to ensure firmware updates are robust and reliable. They encourage feedback and collaboration from the robotics community to further enhance the functionality.

Interested users are invited to explore the Canonical robotics documentation for more information on using snaps for robotics applications.
