The ROSOrin All-in-One Design: Three Robots in One

ROSOrin’s chassis gets a upgrade with a modular design to transform easily! Swap between Mecanum wheels, Ackermann steering, and 4-wheel differential drive in minutes — no tools required. Another upgraded design of Pendulum Suspension Structure keeps all four wheels balanced and evenly loaded, so the robot stays stable on uneven surfaces while its motor encoders track every motion precisely.

Each of ROSOrin’s 3 movement modes is designed for a specific focus:

This chassis uses competition-grade Mecanum wheels made from nylon reinforced with fibers, offering significantly better wear resistance and load capacity compared to standard plastic wheels.

By adjusting the speed and direction of each wheel, it can generate movement in any direction, achieving 360° omnidirectional motion on a flat surface. Whether navigating tight spaces or dodging obstacles, it handles every situation with ease.

Following modern automotive standard design, the Ackermann chassis keeps the rear wheels parallel perfectly. During turns, the difference in steering angles between the inner and outer front wheels enables professional Ackermann steering. Combined with Hiwonder self-developed digital servos, the front wheels achieve precise and responsive control for accurate path tracking.

The chassis features an independent dual-wheel drive system, meaning each side’s wheels operate at different speeds to achieve forward, backward, turning, and even in-place rotation movements. It’s also equipped with high-quality, competition-grade rubber tires that offer exceptional traction and long-lasting durability. Even under frequent use in hands-on teaching or training sessions, the tires maintain stable, reliable performance over time.

Hiwonder ROSOrin with its multimodal chassis costs far less than buying three separate single-mode robots. It also comes with a full-stack solution, including extensive resources such as kinematic analysis for each chassis type, allowing beginners and advanced users to master multimodal robot development with ease.

Quickly switch chassis without the hassle of changing or recalibrating equipment. Reliable operation keeps experiments running smoothly, saving time and making both classroom teaching and research projects much more efficient.

As a professional ROS teaching and research platform, ROSOrin is fully compatible with the entire ROS toolchain. Combining embodied intelligence with multimodal AI models, and equipped with LiDAR and depth cameras, it supports the full spectrum of learning—from beginner-friendly visualization to advanced research-level algorithm development.
