Waveshare WAVE ROVER Flexible Expandable 4WD Mobile Robot Chassis, Onboard ESP32 Module(US Plug)

Features:
1. WAVE ROVER is a four-wheel-drive mobile robot chassis with an all-metal body. It has strong off-road traversing capabilities and shock absorption performance. All codes are open source and can be developed again.
2. Supports multiple hosts (Raspberry Pi, Jetson Nano, Jetson Orin Nano, etc.). The host can communicate with the ESP32 slave through the serial port.
3. Equipped with four N20 reduction motors and high-quality gearboxes, the mobile robot can travel at high speeds and has strong power.
4. Built-in 3S UPS power module, supports 3 18650 lithium batteries (series connection, not included), provides uninterrupted power supply for the robot, and supports charging and power output at the same time.
5. Built-in multi-functional robot driver board, based on ESP32, with onboard WIFI and Bluetooth, used to drive serial bus servos, output PWM signals, expand TF card slots, etc.
6. WAVE ROVER uses flexible rubber tires, which greatly reduces the impact of complex terrain and easily meets the needs of high-speed driving, shock absorption, and off-roading.
7. Comes with a mounting plate that can be used to install hosts (Raspberry Pi 4B, Jetson Nano, Jetson Orin Nano, etc.), LD19/STL-27L lidar, and gimbal cameras, providing more possibilities for secondary development.
