Robotic Arm And Gripper - dji Robomaster EP Core User Manual

ROBOMASTER EP Core User Manual
When in use, DO NOT touch the servo to avoid injury.
DO NOT hit the servo. Otherwise, it may reduce the service life of the servo or even lead to
permanent damage.
When the servo overload warning prompts appear in the app multiple times, stop the
operation immediately and check the operation and the structure of the robotic arm or servo.
When mounting the servo onto the robotic arm, use the programming interface with caution
to avoid affecting the limit structure of the robotic arm.
When the servo is in PWM mode, its status cannot be displayed on a computer. The
current status of the servo can be retrieved from the LED indicator.

Robotic Arm and Gripper

Introduction
The robotic arm of the robot supports precise FPV control and can be used with the gripper. Grab
and move objects by controlling the robotic arm and gripper in first person view (FPV) in the
RoboMaster app.
Use Instructions
DO NOT apply external force to the robotic arm or gripper when they are in use.
The movement range of the robotic arm and the grip distance of the gripper can be controlled. The
horizontal movement range of the robotic arm is 0-0.22 m while the vertical range is 0-0.15 m. The
grip distance of the gripper is 10 cm.
To avoid injury, DO NOT touch the robotic arm or gripper when they are in use.
DO NOT hit or damage the robotic arm or gripper. Otherwise, the performance may be
negatively affected or the servo may become abnormal.
Clean foreign objects like droplets in a timely manner. Otherwise, the surface of the structure
may corrode.
Gripper PWM Port
The port pin is shown below:

4 3
The gripper supports torque control mode. The PWM signal has a frequency of 50 Hz and a duty
cycle ranging from 2.5%-12.5%. 2.5%-7.5% corresponds to the gripper's closing force (Max-0), and
7.5%-12.5% to its opening force (0-Max).
