TurtleBot 4 is the next-generation of the world’s most popular open source robotics platform for education and research, offering better computing power, better sensors and a world class user experience at an affordable price point.
TurtleBot 4 comes in two models – TurtleBot 4 Standard and TurtleBot 4 Lite. Both are equipped with an iRobot® Create3 mobile base, a powerful Raspberry Pi 4 running ROS 2, OAK-D spatial AI stereo camera, 2D LiDAR and more. All components have been seamlessly integrated to deliver an out-of-the-box development and learning platform. Tap into the thriving open source ROS developer community and get started learning robotics on day one.
TurtleBot 4 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.
TurtleBot 4 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.
TurtleBot 4 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 out-of-the-box and up to 15 kg with a custom configuration, 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 a charging dock.
Once you’ve mastered the basics, easily expand the capabilities of TurtleBot 4 by adding your own sensors and custom payloads. Accessible USB ports, power breakouts and a top mounting plate make it easy to integrate third-party hardware and components. With ROS 2 and its support for micro-ROS, expansion and integration of embedded microcontrollers is made easier than ever.
TurtleBot 4 comes with comprehensive courseware material, including lesson plans, lecture content, tutorials and sample tests, allowing educators to easily incorporate TurtleBot into robotics training courses.
TurtleBot is an open source platform and you can get the design and software here. You’re encouraged to try it out, extend it, or build your own. For every TurtleBot 4 shipped, a portion of the proceeds goes to the Open Robotics for the continued support of the development, distribution, and adoption of open source software in robotics research and education.
TurtleBot 4 comes in two models: TurtleBot 4 Standard and TurtleBot 4 Lite. While both models are built on the powerful iRobot® Create 3 mobile base, TurtleBot 4 offers an OLED screen, a better Spatial AI stereo camera, and a mounting plate with accessible user power and USB ports for easily integrating payloads and accessories.

The RPLIDAR A1M8 is a 360 degree Laser Range Scanner with a 12m range. It is used to generate a 2D scan of the robots surroundings. Both the TurtleBot 4 and TurtleBot 4 Lite use this sensor. For more information, click here.
The OAK-D-Lite camera from Luxonis uses a 4K IMX214 colour sensor along with a pair of OV7251 stereo sensors to produce high quality colour and depth images. The on-board Myriad X VPU gives the camera the power to run computer vision applications, object tracking, and run AI models. For more information, visit the Luxonis documentation.
The OAK-D-Pro offers all of the same features the OAK-D-Lite has, but uses higher resolution OV9282 stereo sensors and adds an IR laser dot projector and an IR illumination LED. This allows the camera to create higher quality depth images, and perform better in low-light environments. For more information, visit the Luxonis documentation.
