WHEELTEC S300 Mini Differential Drive Robot

The WHEELTEC S300 Mini Differential Drive Robot is a compact, high-performance mobile research platform designed for space-limited indoor environments. Equipped with advanced spatial sensors, open-source ROS architecture, and a robust hub-motor chassis, it is ideal for advanced robotics students, educators, and researchers looking to develop autonomous navigation applications.

Advanced autonomous recharging capabilities

The S300 Mini features support for automatic recharging and is driven by efficient hub motors. This fully open-source chassis can also be configured with an optional C16 multi-line LiDAR system to meet demanding spatial mapping requirements.

Optimised for space-constrained environments

Designed specifically for smaller indoor testing areas, the S300 Mini packs the same core sensor suite as the larger Pro model into a more compact footprint. It features an independent suspension chassis, dual TOF LiDAR, a Gemini Pro binocular depth camera, and a comprehensive ultrasonic collision avoidance system.

High-performance hardware specifications

The chassis measures 530 by 450 by 425 millimetres, weighs 51 kilograms, and supports a maximum payload of 20 kilograms. Driven by 5-inch hub motors, it achieves speeds up to 2.0 metres per second and offers an impressive battery life of approximately 13 hours under unloaded navigation testing.

Versatile ROS control and processing

Users can choose between an Nvidia Jetson Orin Nano Super 8GB or Orin NX Super 16GB master controller. The system supports ROS1, ROS2, mobile app control, and a multi-mode smart controller, backed by fully open-source chassis drive code, schematics, ROS source code, and 3D models.

Robust power and sensor array

The robot is powered by a high-capacity 24V 20000mAh lithium iron phosphate battery. Its integrated sensor array includes two TOF LiDARs, two depth cameras, and five ultrasonic sensors to ensure precise obstacle detection and navigation.
