Referee System Overview
The Referee System is a fully autonomous electronic penalty system that can detect projectile attack damage and monitor chassis
movement power as well as other robot parameters. The Speed Measurement Module monitors a robot's projectile launching speed
and rate; the Camera Transmission Module provides the user with a rst-person perspective of the robot; the RFID Interaction Module
interacts with the battleeld; and the Localization Module provides a user with a real time high-precision mini-map. A user can use
multiple Referee Systems to form a multi-robot combat system.
The Referee System is composed of the following:
1. The robot side of the Referee System (hereinafter referred to as "Robot Side")
2. The PC client (hereinafter referred to as "Client") and the PC server (hereinafter referred to as "Server")
The Robot Side is composed of the following modules:
1. Main Control Module: the "brain" of the Robot Side. Automatically calculates damage according to data passed back from other
modules. In addition, this module's light bar displays the status and HP of the Robot Side in real-time. The Small Armor Module
can be mounted onto the rear of the Main Control Module by using Armor Mount A (left) and Armor Mount A (right).

Start Battle
Multiple Referee Systems can be combined to form a multi-robot combat mode. A user can choose to set up a local area network (LAN)
for online combat.
If a local area network (LAN) is set up, the Server must be used, and a user must be able to check the HPs of all Robot Sides on the
Server. A user may also use the Client, paired with the VTM Receiver, to operate a robot from a first-person perspective, check the
HPs of all Robot Sides, and determine the outcome of the competition automatically with the aid of the server.
If a LAN is not being used, the outcome of the competition can be determined only by the HP displayed on the Main Control Module
light bar of the Referee System. Additionally, a user may use the Client paired with the VTM Receiver to operate a robot from a
first-person perspective, but cannot check HPs of the Robot Side nor determine the outcome of the competition automatically.
Users may opt to use base robots or customize competition rules for a more personalized experience. The examples below describe
these situations in ascending order of complexity:
1. 1v1 Mode
1v1 Mode works as follows: A user may select any two Robot Side configurations from the configuration table to be applied to two
robots respectively. One robot will be assigned to the Red team, and the other to the Blue team. You may choose whether to set up a
LAN or use a base for the competition. The table below presents an example of a starting line-up:

Introduction to the Robot Side Module Initialization
To ensure fair competition, it is important that all of the Referee System modules are working properly. Therefore, a Robot Side will
initialize each module after powering up. If the initialization process fails, the Main Control Module light bar will be steadily lit in
yellow.
Setting Armor Module IDs
A Robot Side can have multiple armor modules. They should be numbered so that the Robot Side can easily identify which armor is
being attacked. The following shows how to number armor modules:
1. On the function page of the Main Control Module, proceed as shown to enter the Armor ID Setup page:
2. On this page, select "Armor ID Reset" to make the system enter the Armor ID Reset status:
At this point, the armor light bar flashes at a certain frequency (if the Robot ID is on the Red team, the red indicator light flashes; if
the Robot ID is on the Blue team, the blue indicator light flashes).
3. Strike each Armor Module in succession with a consistent amount of force. If the armor light goes off and then comes back on, the
armor ID has been set successfully. The ID number of the Armor Module that was hit first is 0, and the ID number is sequentially
incremented according to the order in which the modules were struck.
4. After completing the above operations, check whether the armor ID has been set successfully by looking up the version number
of the Armor Modules. If the read number of effective Armor Modules is the same as the number of Armor Modules installed, the
procedure is complete.
5. On the Armor ID Setup page, if you select "Armor ID 0," the IDs of all Armor Modules connected to the Main Control Module will
be set to 0. This function is mainly used to set an armor module to a specified ID.
Be sure to set the ID of an Armor Module in advance of using the Referee System, and ensure that the IDs of Armor
Modules connected to the same Main Control Module are not repeated. If not set properly, the Armor Module ID will be
detected as missing during the Robot Side initialization, and will be identied as Ofine during use. The power output of
the Robot Side will not be possible to enable, and the Main Control Module light bar will be displayed as yellow.
Camera Transmission Module Instructions
The Camera Transmission Module is divided into the VTM Transmitter and the VTM Receiver, which use "Auto pairing" and "Manual
pairing" as their respective connection methods.
1. "Auto pairing": As the transmitter ID is bound to the Robot ID, videos and images can be properly transmitted only when IDs are
matched between the transmitter and the receiver. The table below shows the matching relationship between the transmitter and the
receiver:

4 The Transmitter is successfully paired with the Receiver when their Network Activity indicator lights become steadily lit in
green. If they still have not been paired after a prolonged period of time, please reboot the Camera Transmission Module and
repeat step 3 to pair them again.
To receive videos and images using a Client, the PC side should be installed with a video capture card. If no card is
available, the VTM Receiver can be directly connected to a monitor via an HDMI cable for display.
Only seven camera transmission channels are open for user debugging. When more than seven camera transmission
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. During combat, it is recommended to set to Red 1-Red 3 and Blue 1-Blue 3 to avoid
conflict.
Introduction to the Main Control Module User Interface
To allow users to better carry out automatic control and obtain real-time competition data, a UART I/O interface is open 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
current and voltage value output from the chassis. In addition, user-customized data can be uploaded to the Client and will be displayed
on the operator UI. A user can check the interface protocol instructions to implement this feature according to different competition
specication manuals.
Descriptions of line sequence:
1. +: NONE, this line is vacant and not connected
2. G: GND, GND line for serial communication
3. Tx: transmission line for serial communication data
4. Rx: receiving line for serial communication data

Introduction to Robot Side Module Updates
1. Connect the serial communication module to the UART interface of the Referee System interaction screen. The interface is dened
in the gure below:
Descriptions of line sequence:
a. *: NONE, this line is vacant and not connected
b. G: GND, GND line for serial communication
c. Tx: transmission line for serial communication data
d. Rx: receiving line for serial communication data
A baud rate of 921600 is used when updating the Referee System. Ensure that the serial communication module can function
reliably at this communication rate; otherwise, updating may be slow or even fail.
