RoboMaster Referee System User Interface Guide
To help users carry out automatic control and obtain real-time competition data, a UART interface is
available on the Robot Side to output Robot Side data.
Output data includes the remaining time in the competition, the robots' remaining HP, and real-time
power output from the chassis. In addition, user-customized data can be uploaded to the Client and will
be displayed on the operator UI. Users can view the interface protocol description at the following URL:
https://github.com/RoboMaster/referee_serial_port_protocol.
The Referee System user interface is part of the Power Management Module. The exact location is shown
below:
Student
Serial Port
When using several Video Transmitter Modules to transmit video at once, to avoid unclear
images due to mutual interference, you should first ensure that one set of Video Transmitter
Modules is connected, and then after the Client displays the images, enable the other Video
Transmitter Modules.
Only six VTM channels are available for user debugging in Mainland China and other regions.
When more than six video transmitter modules work at the same time, transmission interference
may occur. Therefore, you can select only the red team or only the blue team for debugging, or
during combat, set Red 1-Red 3 and Blue 1-Blue 3 to avoid conflict.
Only nine VTM channels are available for user debugging in Japan, of which channels 20-23
are W52-enabled, and channels 24-28 are 5.7 GHz-enabled. For 5.7 GHz-enabled channels,
please apply for the usage license. If the 5.7 GHz usage license is not obtained, please set
Red 1-Red 2 and Blue 1-Blue 2 for debugging to carry out a combat not exceeding 2v2. If the
5.7 GHz usage license is obtained, you can select only the red team or only the blue team for
debugging, or during combat, set Red 1-Red 4 and Blue 1-Blue 4 to avoid conflict.
Line sequence descriptions:
1. Rx: receiving line for serial
communication data
2. Tx: transmission line for
serial communication data
3. G: GND line for serial
communication
Checking Functions on the Robot Side
After the Robot Side is installed, follow the instructions to connect each module and carefully read all the
usage instructions mentioned above.
On first power-up, carry out the following checks:
1. Check that the supply voltage is correct and whether the polarity of the power supply is reversed (the
input voltage for the Referee System must not exceed 24 V).
2. Ensure that the wires are firmly connected to each module and that there is no risk of them being
entangled in a moving mechanism.
3. Turn on the battery power, wait until the Main Controller Module of the Referee System has started
up (startup may take about 20 seconds), and then check the color of the bar on the Light Indicator
Module. When the Main Controller Module of the Referee System is powered on for the first time after
installation, a yellow light is displayed after startup. As the Armor Module IDs have not been set, the
Main Controller Module is not connected to the Server.
4. Set the Armor Module IDs (for details, refer to "Set Armor Module ID").
