Detailed information
-
This product is equipped with a 1440Wh (24V 60Ah) Li-Fe battery. Compared to the basic model, the 4WDS Rover X120A, the battery capacity has been expanded to about three times. In research and development mobile robots, in addition to various measuring instruments, it is common to have computing devices for image processing and information processing, as well as driving components, and as the required processing and tasks become more advanced, there is a tendency for the equipment to become larger. The 4WDS Rover X120A-LB can achieve longer operating times even when equipped with many expansion devices.
-
The 4WDS Rover X120A-LB supports wireless communication via Wi-Fi and wired USB serial communication. By using specified commands, it can be controlled from various devices such as PCs and tablets. Additionally, a wireless controller board for robots and a gamepad are included as standard, allowing the unit to be operated wirelessly without connecting to a PC. It can move forward and backward and rotate using the analog stick, making it usable for manual control for operation confirmation and as a means of operation in emergencies. *Product specifications are subject to change without notice.
-
The main frame of this product is made of aluminum components. It has sufficient strength while being easy to process, allowing users to easily perform various expansions by themselves. It is also possible to drill mounting holes in the upper panel to add parts, providing the necessary flexibility for promoting research and development.
-
The control board "VS-WRC071" equipped in this product features the ESP32-S3-WROOM-1 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 themselves. *Note: When programming the VS-WRC071 using the Arduino IDE, an environment with Arduino IDE version 1.8.19 or higher is required.*
-
This product is equipped with a standard "emergency stop switch." Additionally, the installation position of the emergency stop switch can be freely changed as long as there are no issues with the length of the wiring or interference with other devices. It is assumed that users will change and use it according to the actual operational conditions and the installation status of any additional expansion devices.
-
The 4WDS Rover X120A-LB supports ROS 2 message communication, allowing for ROS message communication using micro-ROS by connecting to a device running ROS via Wi-Fi or a USB cable. The sample firmware enables sending movement speed command values to the Mega Rover using the geometry_msgs/msg/Twist type from ROS, as well as retrieving the current speed and battery voltage from the Mega Rover. Additionally, by modifying the firmware, users can send and receive any messages beyond those mentioned above. Please note that you will need to prepare a separate device to run ROS (such as the ROS PC (NUC14) option). The operating environment for the recommended devices from our company is as follows (additional setup of libraries not included with this product may be required).
