Introduction
The RoboMaster Dart Trigger Device is an interactive device designed for the Dart System in the RoboMaster
competition. With the trigger device mounted to the tip of the dart, the RoboMaster Dart Detection Module can
receive and decode the infrared information emitted from the trigger device to judge the type of attack when
the trigger device hits the module. The trigger device will continuously glow red or blue when the dart is in ight
to distinguish which team the dart belongs to as well as to indicate the ight trajectory.
The trigger device adopts a hollow structure design, so that a camera of a compatible size can be installed
to improve accuracy with the help of visual algorithms. The TPU material of the outer covering provides an
eective buer to protect the camera and the internal structure of the dart when it hits the target.

Usage
Status Descriptions
Conguration Status
The trigger device enters conguration status within 3 seconds after powering on. In this status, users can
congure the light color or switch modes.
Work Status
The trigger device automatically enters the work status after being powered on for 3 seconds or when
conguration is completed. In this status, the trigger device will light up in the preset color for 5 seconds if it
detects acceleration or impact. If the trigger device detects acceleration or impact again within the 5 seconds,
the timer for the light will reset.
Malfunction Status
If the hardware is damaged, the trigger device will blink red and blue alternately to indicate that the trigger
device needs to be replaced. Make sure to replace any damaged hardware before competition.
Mode Descriptions
The trigger device includes Practice mode and Competition mode. Practice mode is set by default when using
for the rst time.
Mode Switch
When set to Practice mode and in the conguration status, the trigger device will enter Competition mode if
it receives a signal of entering Competition mode from the designated transmitter. In Competition mode, the
trigger device will not respond to a standard NEC protocol signal.
When set to Competition mode and in the conguration status, the trigger device will exit from Competition
mode and enter Practice mode if it receives an exit signal from the designated transmitter.
Practice Mode
In Practice mode, the trigger device will glow solid in the last preset color after powering on. If there is no
operation within 3 seconds, the trigger device light will turn off and enter work status. If a standard NEC
protocol signal is received within 3 seconds, the trigger device will blink a dierent color three times before
entering work status.
Competition Mode
In Competition mode, the trigger device will blink in the last preset color at a frequency of 3 Hz. If there is no
operation within 3 seconds, the trigger device light will turn o and enter work status. If a conguration signal
from the designated transmitter is received within 3 seconds, the trigger device will blink in the corresponding
color three times before entering work status.
