It maintains a transportable weight of approximately 40 kg while achieving about four times the operating time (based on experiments and calculations conducted in our company). 【Options for Purchase of ROS-Compatible Transport Robot】 By requesting at the time of order, we will ship the robot with various options installed. - LRF Option (TG30) - 3D LiDAR Option - Bumper Option - Power Supply Board Option for Expansion Devices - Installation of Raspberry Pi 4B 4GB Version - Wireless Charging Option - ROS PC Option - Camera Mount Option - Depth Camera Option - Remote Control Option (without/with PC) - Pan-Tilt Device Option (without/with camera) - Robot Arm AMIR 740 - Lift Option - Wired Remote Control Option 【Use Cases】 Research and development robots, transport robots, two-wheel drive robots, autonomous driving robots, delivery robots, AGVs, and more. *For more details, please feel free to contact us.

Detailed information

  The Mecanum Rover G40A-LB is equipped with a 1440Wh (24V 60Ah) Li-Fe battery, expanding the battery capacity to approximately five times that of the basic model, the Mecanum Rover Ver. 3.0, which has 288Wh. In our internal measurements, the operating time of the Mecanum Rover Ver. 3.0 is about 28 hours, while this product achieves approximately 113 hours, resulting in about four times the operating time (actual operating time may vary significantly depending on the equipment mounted, operating programs, usage conditions, etc. Please consider this as a reference value). In research and development mobile robots, various measuring instruments, as well as computing devices for image processing and information processing, are often mounted, and as the required processing becomes more advanced, there is a tendency for the equipment to become larger. The Mecanum Rover G40A-LB can achieve even longer operating times for applications that require the installation of many expansion devices.

  This product features four mecanum wheels that allow for the free combination of forward/backward, left/right, and rotational movements. A major 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 robot body. 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 real-world demonstration experiments. *This product is not designed for passenger use.

  The 4WDS Rover X120A is equipped with a steering mechanism that can independently control all four drive wheels. By appropriately controlling the angle and rotation speed of each drive wheel, it allows for movement in the forward, backward, and lateral directions without changing the orientation of the robot, as well as enabling ultra-tight turns (turning in place) without skidding the wheels. Additionally, each wheel is equipped with a suspension mechanism, ensuring that all four wheels maintain proper contact with the ground, which enhances straight-line stability and control accuracy. Compared to other omnidirectional wheels like omni-wheels and mecanum wheels, the simple structure of the wheels themselves is also a feature, making them resistant to dirt and dust. *This product is intended for indoor use only. Outdoor use is not anticipated.

  The Mekanum Rover G40A-LB supports wireless communication via Wi-Fi and wired USB serial communication. By using designated commands, it can be controlled from various devices such as PCs and tablets. Additionally, the wireless controller for robots, "VS-C3," is included as standard, allowing for wireless operation of the unit without connecting to a PC. It can also be manually operated using an analog stick for forward and backward movement and rotation, making it suitable for operation checks and emergency control methods.

• 

  The control board "VS-WRC058c" included in this product is equipped with the ESP32-WROOM-32 microcontroller, allowing users to create control programs using the Arduino IDE. Sample code will be 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." Additionally, the installation position of the emergency stop switch can be freely changed as long as there are no issues with wiring length or interference with other devices. It is assumed that users will replace and use it according to the actual operational situation and the installation status of any additional expansion devices.

• 

  The Mecanum Rover G40A-LB 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 enables sending movement speed commands to the Mecanum Rover using geometry_msgs/Twist or geometry_msgs/msg/Twist types, as well as retrieving current speed and battery voltage from the Mecanum Rover. Additionally, by modifying the firmware, users can send and receive any messages beyond those mentioned above. Please note that a separate device to run ROS must be provided.
