Yuhesen FR-Mini

The Yuhesen FR-Mini (often categorized within the FW-Mini series) is an ultra-compact, high-performance Unmanned Ground Vehicle (UGV) chassis designed for research, education, and indoor/outdoor navigation testing.

Think of it as the “Swiss Army Knife” of robot bases—small enough to fit in a trunk but sophisticated enough to handle complex autonomous driving algorithms.

Key Features

Omnidirectional Mobility: Equipped with a Swerve Drive system (four-wheel drive and four-wheel steering), allowing it to move in any direction, pivot on the spot, and execute lateral shifts.
Modular Architecture: Designed as an open-source platform, it easily integrates with LiDAR, GPS, depth cameras, and IMUs. It is fully compatible with ROS/ROS2 (Robot Operating System).
All-Terrain Performance: Despite its “Mini” name, it features independent suspension and high-torque hub motors to handle obstacles like speed bumps and slopes up to 20°.
Industrial-Grade Safety: Includes a multi-layer safety framework with physical emergency stops, logic interlocks, and optional anti-collision sensors.
