This WAVE ROVER is a full metal body 4WD mobile robot chassis, which features superb off-road crossing ability and shock-absorbing performance, open source all code for secondary development. It supports multiple host computers (Raspberry Pi, Jetson Nano, Jetson Orin Nano, etc), the host computer can communicate with the ESP32 slave computer through the serial port. Equipped with four N20 geared motors using a high-quality gearbox, which allows the mobile robot to drive at high speed with great power. Built in 3S UPS power supply module, supports 3 x 18650 Li batteries (in series, NOT included), which provides uninterruptible power for the robot and supports charging and power output at the same time. Built in multi-functional robot driver board, based on ESP32, with onboard WIFI and Bluetooth, for driving serial bus servos, outputting PWM signal, expanding TF card slot, etc.This WAVE ROVER adopts flexible rubber tires which greatly reduce the impact of complex terrains, can easily meet the needs of high-speed driving, shock absorption, and off-road. Comes with a mounting plate, can be used to install the host computers (Raspberry Pi 4B, Jetson Nano, Jetson Orin Nano, etc.), LD19/STL-27L lidar, and pan-tilt camera, providing more possibilities for secondary development.

Description:
Equipped with N20 reduction motors that use high-quality gearboxes, enabling it to travel at a high speed of 1.25m/s.The flexible rubber tires significantly reduce the impact of complex terrains on the product.It features a 0.91-inch OLED screen for interactive purposes.The product is designed with a charging interface and automatic download circuit, allowing it to be used while charging.The UPS power module on board contains an INA219 acquisition chip, facilitating real-time monitoring of battery voltage and charging current.The UPS power module utilizes three series-connected 18650 batteries with a large capacity of 7800mAh, providing a higher output current and stronger motor power.It also offers 5V and 3.3V outputs for expanding other devices.The module includes a lithium battery protection circuit, offering functions such as overcharging, over-discharging, overcurrent, and short-circuit protection.The sample code is developed using ArduinoIDE, eliminating the need for manual configuration of the compilation environment. Upon startup, the ESP32 automatically establishes a WIFI hotspot. Users can connect and log in to the control interface using a smartphone (Android/iOS) or a computer (Linux/Windows/Mac) with any Chromium-based browser, without requiring an app download.The slave ESP32 can be used to drive DC motors and serial bus servos and supports interfaces for OLED screens, TF card slots, a nine-axis IMU module, WiFi, and Bluetooth. Even without installing an upper-level device, it can be used independently.The system can be extended with various host devices, using serial communication to transmit control data in JSON format.The entire code is open-source and comes with online rich development documentation and tutorials.The open-source resource includes planar drawings and chassis structural drawings, including 3D models, facilitating secondary development.
