ESP32 MicroROS Robot Car Kit (VM Controller), ROS2 Humble, TOF Lidar, 7.4V 2000mAh – Mac Not Supported

Overview

ESP32 MicroROS Robot Car Virtual Machine as controller (Mac Not Support) is a ROS2 educational robot car that offloads complex computing tasks to a PC virtual machine environment. The robot uses an onboard ESP32 co-processor and MicroROS WiFi UDP communication to transmit sensor/data to the PC virtual machine, where calculations are completed and control decisions are generated.

This platform supports ROS2 Humble and Python3 programming, and is designed for learning and development workflows including lidar obstacle avoidance, following, mapping navigation, RViz simulation, and multi-machine synchronization control.

Key Features

• Virtual machine master control: Uses a PC-side virtual machine as the master controller to reduce learning cost, improve algorithm computing efficiency, and support DIY/upgrades. Note: Mac system is not supported.
• Onboard ESP32 processor: Built-in Wi-Fi and Bluetooth functions; supports MicroROS for real-time data transmission between the robot and the virtual machine.
• ROS2 Humble support: This product uses ROS2 Humble.
• Multi-master support: In addition to the PC virtual machine master, also supports using Raspberry Pi 5 or Jetson Nano as the desktop master to communicate with the chassis (with supporting usage documents and corresponding system image).
• TOF lidar functions: Lidar obstacle avoidance, lidar tracking, lidar guard, and lidar patrol.
• Remote control options: iOS/Android APP remote control; multi-machine handle/keyboard control in real time for synchronous movements. Handle controller is not included.
• Robot information release: The chassis can release control data from sensors such as radar, IMU, speed, and buzzer to the virtual machine.
• Chassis & power: Aluminum alloy body; 4PCS 310 encoder motor; 7.4V large capacity battery pack.
