Features:
WHEELTEC R3 Series Smart Car Chassis
* All-metal double-layer frame
* High-precision Hall encoder
* DC reduction motor
* Double-layer all-metal plates
* ROS extension
* Supports secondary development
* Video tutorials available
* Innovative product

Hall Encoder
* The encoder features a pull-up output. By default, it is pulled up to the power supply VCC pin, allowing direct collection by the microcontroller.

Adjustable Chassis Structure (for Ackerman Chassis)
* Under normal circumstances, debugging of the positive Ackermann structure, reverse Ackermann structure, and differential drive car may require the purchase of three cars simultaneously. Our car can achieve the functionality of all three types through structural and code compatibility and replacement.

Simple and User-Friendly Industrial Design
* Research robots need to meet requirements such as aesthetic appearance and ease of use. The bottom of the chassis features a closed metal sheet design, providing better protection for components with lower development frequency and higher power consumption, such as the battery and motor, effectively eliminating potential safety hazards. The upper part uses a streamlined bracket, facilitating secondary development and ROS expansion, as well as making debugging and plug-in operations more convenient.

Metal Omni Wheel - Patent Product
* The R3 series Ackermann/differential drive version is equipped with omnidirectional follower wheels, allowing for a quick switch from Ackermann steering to differential drive mode.

High-Quality Tires
* 65mm rubber tires: They are used for Ackermann or differential drive cars, with a high friction coefficient, ensuring no slippage during high-speed operation.

Provided Tutorials
* STM32 low-level source code and ROS communication video tutorials come with bilingual (Chinese and English) subtitles. We provide a detailed explanation from STM32 code analysis to the building of the ROS basic communication framework at the code level.

Serial Data Visualization Upper Computer Compatible with Windows System
1. The upper computer monitors various parameters in waveform and graphical formats. It is an ideal choice for in-depth analysis of PID, balancing cars, inverted pendulum robots, and more.
2. The upper computer itself provides rich and intuitive data visualization functions, including multi-channel individual or simultaneous display, histograms, 3D cubes, 3D charts, and a level gauge.
3. All data can be saved in text or table formats. Users can perform offline analysis using the upper computer or other methods.

Bluetooth & WiFi Version APP, Supports Android and iOS
1. The APP supports gravity sensing remote control and dual-hand button remote control modes.
2. The APP supports a 5-channel waveform display interface, allowing waveform viewing without the need for data cables at any time.
3. The APP supports a 9-channel parameter adjustment interface, enabling online adjustment of PID parameters.
4. Optimized low battery alarm mechanism, with the app accurately pushing low voltage alerts.
5. It supports BLE Bluetooth 4.0 module.
