The Megarover F120A achieves a transportable weight of approximately 120 kg, similar to previous models, by equipping large wheels and motors. It can comfortably carry various sensors and devices within its system. *This product is not designed for passenger use. Additionally, due to its large size, please exercise sufficient caution during development and operation. The Megarover F120A features a wheel configuration that combines two-wheel drive with rear casters. Since it operates under normal wheel control, its movements, such as forward and backward motion and left and right turns, are easily understood by those around it, providing advantages in durability and quietness. Despite its large size, it has achieved a maximum speed of 1.6 m/s in actual measurements, making it suitable for various research and development applications. It is also characterized by its stability in practical use, as it is less prone to wheel slip. By adopting a direct drive motor for wheel propulsion, the operating noise has been reduced compared to previous products.

The control board "VS-WRC058" equipped in this product features the ESP32-WROOM-32 microcontroller, allowing users to create control programs using the Arduino IDE. Sample code is provided with the product in the form of an Arduino library, enabling users to customize the firmware on their own. *Note: When programming the VS-WRC058 using the Arduino IDE, an environment with Arduino IDE version 1.8.13 or higher is required.*

This product comes standard with an "emergency stop switch," which was previously an optional accessory in conventional models. Additionally, whether the side with the emergency stop switch is designated as the "front" or "back" of the cart robot can be switched by changing the wiring or programming. It is assumed that users will interchange this based on actual operational conditions and the configuration of any additional expansion devices.

This product supports ROS 1 and ROS 2 message communication, allowing for ROS message communication using rosserial or micro-ROS by connecting to a device running ROS via Wi-Fi or USB cable. The sample firmware can send movement speed command values to the cart robot using either geometry_msgs/Twist or geometry_msgs/msg/Twist types, and it can also retrieve the current speed and battery voltage from the cart robot. Additionally, by modifying the firmware, users can send and receive any arbitrary messages beyond those mentioned above. Please note that you will need to prepare a separate device to run ROS. The recommended operating environment for the devices we suggest is as follows (additional setup of libraries not included with this product may be required). *Additional setup of libraries not included with this product may be required.
