attached as the "Unloaded" of the robot.
(1) Default Values
In the "Run Settings" section, the default values have been set for the robot's state without any
brackets installed.
(2) External Structure Size Requirements
To ensure safe use, the following considerations should be taken into account when designing
the installation of external fixed structures:
⚫ After the installation of the external structure, the fixed bracket should not exceed 250mm
on either side of the robot's chassis outline
⚫ After the installation of the external structure, it should not extend beyond 400mm at the
rear of the robot
PUDU T300 Operation Guide

12
⚫ After the installation of the external structure, it should not extend beyond the front pillar
of the robot.
To ensure that the robot can use the charging station for charging, the position of the charging
station needs to be considered when designing the external structure to avoid obstacles during
automatic return charging.
(3) Configuration process after fixing the external structure
After fixing the external structure, it is necessary to enter the "Settings" - "Robot Settings" - "Run
Settings" to modify the dimensions of the unloaded state after fixing the bracket. The parameters
need to be input based on the actual size of the fixed bracket.
The parameters to be input are:
The dimension value of the fixed bracket protruding from the rear of the robot chassis
after installation. Input range: 0~400, default: 0, unit: mm.
The total width of T300 + the fixed bracket after installation. Input range: 500~1200,
default: 500, unit: mm.
After inputting the corresponding parameters, T300 will take into account the dimensions of
the outline after fixing the bracket to avoid collisions with surrounding obstacles.
During the parameter input process, the current robot's minimum pass width and minimum
width for U-turn will be displayed in real-time.
4.2.2 Parameters related to the lifting function
Caution
The lifting feature is only available on the WTIDL1 model.
When performing lifting tasks, the robot can carry a rack that provides a larger carrying space
than its own chassis. The T300 chassis is designed to fit under the rack and lift it up.

chassis, achieving a 360° detection around the robot. The specific range is as follows:
Caution:
The LiDAR can only scan the ground plane at a height of 19cm.
If there are transparent objects (such as glass) or reflective obstacles (such as mirrors) in the environment, the
data from the LiDAR may have deviations. It is recommended to place frosted stickers or other markers at a height
of 19cm or set up virtual walls on the map.
(2) RGBD
The robot is equipped with two RGBD cameras on the front side, which can perform
stereoscopic detection of obstacles in front of the robot. The specific range of detection for the robot
is as follows:
PUDU T300 Operation Guide
Version: V1.0.3 Operation Guide
