The educational robotics landscape is rich with platforms, yet many often share similar form factors and incremental features, leaving a gap for a system designed for deep, comparative learning and advanced AI integration. The ROSOrin platform addresses this by introducing a foundational redesign at the hardware level, coupled with deeply integrated multimodal AI, creating a versatile tool for both education and advanced prototyping.
1 Platform, 3 Kinematic Models, Endless ExperimentsThe core innovation of ROSOrin is its patented, modular chassis. It physically reconfigures into three distinct drive systems: Mecanum (omni-wheel), Ackermann (car-like steering), and Differential drive. This isn't a simple accessory swap; it involves a fundamental rework of the mechanical structure and kinematic model, allowing direct comparison of navigation, control, and path-planning algorithms across different mobility paradigms on a single, consistent hardware set. This dramatically expands experimental scope while reducing the need for multiple specialized robots.
Supporting this flexibility is a proprietary swing-arm suspension system that maintains consistent ground contact and weight distribution across all modes and surfaces. This design minimizes wheel slip, ensuring that encoder data fed to navigation stacks (like SLAM) is reliable, providing a stable physical foundation for algorithmic development.

Beyond a agile body, ROSOrin is built to host multimodal Large Language Models (LLMs) fine-tuned for robotics, moving beyond demo-grade chat to enable robust task completion.
- Semantic Understanding & Task Planning: You can issue high-level, natural language commands. For example, telling it "I'm hungry" can trigger a process where it navigates to a kitchen, scans the environment, and reports, "I see eggs and tomatoes; you could make scrambled eggs."
- Dynamic Scene Perception & Tracking: Leveraging integrated vision models, ROSOrin can parse dynamic environments. It can track a moving soccer ball or locate a specific "blue book" on a shelf, demonstrating goal-oriented visual search and pursuit.
- Closed-Loop Task Execution: Using a multi-modal reasoning architecture, it can decompose complex instructions into actionable steps. Given a command like "Measure the distance to the car ahead; if it's beyond 30cm, move forward, otherwise reverse, " it will execute the full perception-judgment-action loop autonomously.
ROSOrin integrates a suite of professional-grade sensors to support a wide robotics curriculum:
- Lidar-Based Navigation: Equipped with a TOF lidar, fused with IMU and encoder data, it supports algorithms like Cartographer and Gmapping for SLAM, and TEB for dynamic path planning and obstacle avoidance. It enables reliable applications like autonomous exploration, point-to-point navigation, and lidar-based person following.
- 3D Vision & Depth Perception: A 3D structured light camera provides depth maps and point clouds, enabling precise object distance measurement and volume calculation. It integrates with algorithms like ORB-SLAM3 and RTAB-Map for dense 3D mapping and advanced scene understanding.
- Advanced Visual AI: The system integrates YOLOv11 for object detection and segmentation, alongside OpenCV and MediaPipe for tasks like gesture recognition, face tracking, and KCF-based object tracking. This allows for projects in human-robot interaction and context-aware vision.
- Multi-Robot Fleet Control: Moving beyond single-agent intelligence, ROSOrin supports coordinated multi-robot operations. Using leader-follower and distributed communication protocols, a fleet can perform formations (line, column, triangle), collaborative exploration, and synchronized tasks controlled via a single interface.
ROSOrin is more than hardware; it's a supported learning pathway. It comes with extensive resources, including:
- Structured Curriculum: Hundreds of lessons covering ROS 2 fundamentals, SLAM, navigation, and AI model deployment.
- In-Depth Documentation: Thousands of pages of developer manuals and code-level explanations.
- Simulation & Real-World Bridge: Complete URDF models for Gazebo simulation and open-source low-level drivers ensure a smooth transition from simulation to physical robot.
- Hands-On Tutorials: Step-by-step video guides that walk through project setup, coding, and debugging.
By solving the "one-robot, one-purpose" limitation through mechanical reconfigurability and integrating serious AI capabilities directly into the ROS 2 workflow, ROSOrin establishes a new benchmark for educational and research platforms. It is designed for those who wish to move past introductory concepts and engage deeply with the comparative analysis of robotics fundamentals and the cutting edge of embodied AI.
