This product features four mecanum wheels that allow for the free combination of forward, backward, left, right, and rotational movements. A significant characteristic is its ability to flexibly respond to external position control, enabling movement to the side or at an angle without changing the orientation of the main cart robot. Additionally, it achieves a load capacity of approximately 40 kg, with a measured maximum speed of 1.6 m/s, making it suitable for large research and development carts while also accommodating practical and operational needs for serious demonstration experiments. *This product is not designed for passenger use.* Recently, autonomous control cart robots often require features such as voice recognition and ambient sound measurement, necessitating that the cart robot operates quietly. This product significantly reduces operational noise compared to previous models by employing in-wheel motors for wheel drive.

The control board "VS-WRC058" included in this product is equipped with 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 themselves. *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 and use it according to the actual operating conditions and the configuration of any additional expansion devices.

The Mecanum Rover Ver. 3.0 supports ROS (ROS1) message communication, allowing for ROS1 message communication using the rosserial package by connecting to a device running ROS via Wi-Fi or USB cable. With the standard firmware, it is possible to send movement speed command values to the Mecanum Rover using the geometry_msgs/Twist type, as well as retrieve the current speed and battery voltage from the Mecanum Rover. Additionally, by modifying the firmware, users can send and receive 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).

The Mecanum Rover Ver. 3.0, like its predecessor, supports a wide range of optional components. It is possible to add sensors and other components according to the application, allowing for the full utilization of the capabilities of large research and development robot carts in various research and development fields.
