TurtleBot4 Mobile Robot TB4 Lite

The Clearpath Robotics TurtleBot 4 Lite Mobile Robot is the next-generation robotic platform for learning the Robot Operating System (ROS). With better sensors, more computing power and support for ROS 2, TurtleBot 4 aims to build on the success of previous versions by providing a low-cost and fully-extensible reference platform for robotics researchers, developers and educators.

The TurtleBot 4 Lite is equipped with an iRobot® Create3 mobile base, a powerful Raspberry Pi 4 running ROS 2, 2D LiDAR and more. All components have been seamlessly integrated to deliver an out-of-the-box development and learning platform.

It features an OAK-D-Lite 4K RGB autofocus camera.

Get Started Quickly

The TurtleBot 4 Lite is the ideal robotics development platform for your custom application.
It ships fully assembled with ROS 2 pre-installed and configured along with detailed user documentation, an Ignition Gazebo simulation model, demo code and a suite of tutorials, allowing you to get started quickly with developing robotics applications.

Sensor Packed

The TurtleBot 4 Lite comes with an array of integrated sensors ideal for many robotics applications. Onboard sensors include the OAK-D spatial AI stereo camera, 2D Lidar, IMU, optical floor tracking sensor, wheel encoders, infrared, cliff, bump, slip detection and more. All onboard sensors are available as ROS topics via the network-connected ROS 2 API.

Modern Mobility

The TurtleBot 4 Lite is built on the iRobot Create 3 educational robot - a sturdy mobile base which provides an array of intelligent sensors for accurate localization and positioning, a 9kg payload capacity and a top speed of .306 m/s. The Create 3 has a standalone ROS interface and unlike previous TurtleBots, it includes integrated batteries and charging dock.

Build & Expand

Once you’ve mastered the basics, easily expand the capabilities of TurtleBot 4 Lite by adding your own sensors and custom payloads. With ROS 2 and its support for micro-ROS, expansion and integration of embedded microcontrollers is made easier than ever.

Classroom Ready

The TurtleBot 4 Lite comes with comprehensive courseware material, including lesson plans, lecture content, tutorials and sample tests, allowing educators to easily incorporate TurtleBot into robotics training courses.

Support Open Source

For every TurtleBot 4 shipped, a portion of the proceeds goes to the Open Source Robotics Foundation (OSRF) for the continued support of the development, distribution, and adoption of open source software in robotics research and education.
