ROS2 System
* The goal of ROS2 is to become an operating system suitable for the majority of robots. Currently, almost all newly launched robotic projects by companies are directly based on ROS2.
* Compared to ROS1, ROS2 cancels the MASTER node management at the application layer, and enhances real-time communication at the middleware layer by adopting DDS (Data Distribution Service). At the system layer, ROS2 adds support for Windows, Mac, and microcontrollers.
* Supports for multi-robot systems
* Cross-platform system support
* Real-time control capability
* Supports microcontroller

Lithium Iron Phosphate Battery with Metal Shell
* Lithium iron phosphate (LiFePO4) batteries use lithium iron phosphate as the cathode material. The battery, with a metal shell and bracket protection, ensures that it won't catch fire or explode under extreme conditions like high temperature, overcharging, discharging, or external impact. Additionally, this battery is known for its high-temperature resistance, stability, and superior charging cycle performance, making it an excellent choice for balancing volumetric efficiency and safety.
* Upgraded Battery Protection Board: The built-in protection board provides comprehensive protection against short circuits, overcharging, and over-discharging, significantly enhancing the safety performance.
* High-Quality A-Class Battery Cells: The quality of the battery cells directly determines the quality of the battery. By using high-quality, original battery cells from leading new energy manufacturers, this battery ensures higher energy density and greater safety.
* Metal Protection Shell: The metal shell assists with heat dissipation, improves the integrity of the appearance, and provides impact resistance.

Battery Specifications
* Battery Pack: 22.4V 6000mAh
* Cutoff Voltage: 16.5V
* Fully Charged Voltage: 25.55V
* Maximum Instantaneous Discharge Current: 40A
* Cell Material: Lithium Iron Phosphate (LiFePO4)
* Charging Current: 3A
* Discharge Performance: Continuous discharge at 15A
* Connectors: DC4.0x1.7mm Female (Charging); XT60U-F Female (Discharge)

Multi-Mode Controller
* The controller supports both wired and wireless connections, with a wireless communication range of up to 25 meters. It features 15 buttons and 6 analog channels, with customizable functions for DIY use. When remotely controlling the robot, it provides vibration feedback for a more immersive experience. Compared to traditional RC controllers, it is better suited for robotic applications.
* Compact in size and ergonomically designed, it offers a comfortable grip.
* The receiver connects via a stable USB interface.

Patented Ackermann Chassis Technology
* All chassis are made of fully machined metal. Equipped with a high-precision suspension system typically found only on premium models, the chassis is capable of handling uneven terrain with ease.
* It uses a clamp-type coupling to secure the wheels, so you'll never have to worry about them falling off again.

GMR High-Precision Encoder
* Upgraded with a 500-line A/B phase GMR high-precision encoder, this new version offers more than 38 times the accuracy of typical Hall encoders (commonly used in similar products on the market). With the GMR encoder, the robot car delivers exceptional performance during low-speed navigation, ensuring more precise movement and control.

Supports Bluetooth Wireless Code Programming
* The Bluetooth module provided with the robot chassis not only allows for remote debugging of the robot but also supports the use of the dedicated Bluetooth programming host developed by WHEELTEC for code flashing. The entire flashing process takes only a few seconds, greatly facilitating secondary development.

Magnetic Quick-Release Mounting Base
* The battery attaches to the chassis using a magnetic connection, allowing for instant battery swaps with zero downtime. During normal use, the combination of magnetic force and a positioning block at the base ensures the battery remains securely in place.

C50C STM32 Main Control Board:
* The mainboard is designed for smart robot cars and ROS development. One board is compatible with various vehicle types such as Ackerman, differential, Mecanum, and four-wheel drive, supporting up to 4 motors with encoders and 2 PWM servos simultaneously. It provides dual 5V 5A interfaces for powering external devices like Raspberry Pi, Jetson Nano, and other peripherals. The industrial-grade 4-layer board includes full ESD protection for user interfaces. The code and schematic are fully open source.

D50A Motor Driver Module:
* It is a dual-channel 12A high-current motor driver module with over-voltage, under-voltage, and over-temperature protection for safer operation. The reverse-polarity protection socket connects directly to the STM32 main control board via cable for easier use.
* 4-Layer PCB for Enhanced Current Handling: While most similar products on the market use low-cost 2-layer PCBs, this driver module features a higher-cost 4-layer PCB. This significantly improves current handling capability and allows for a much higher and more stable continuous output current.
