End Effector 
The end effector, installed on the front end of the wrist of the 
robotic arm, is used to install special tools (such as grippers, 
vacuum gripper, etc.), which can directly perform work tasks. 
Enable Robotic Arm 
Power on the robotic arm and turn on the motor of the robotic 
arm. After the robotic arm is enabled, it can start to move normally. 
TCP 
Tool center point. 
TCP Motion 
TCP motion is the Cartesian space motion, with target position in 
Cartesian space coordinate and the end follows the specified 
trajectory(arc, line, etc.). 
TCP Payload 
(End Payload) 
The payload weight refers to the actual (end tool +other object) 
weight in Kg; the X / Y / Z-axis indicates the position of the center 
of mass of the TCP relative to the default tool coordinate 
system,with unit of mm. 
TCP Offset 
(Tool Center Point 
Offset) 
Set the relative offset between the default tool coordinate system 
at flange center and the actual tool coordinate system, with 
distance unit of mm. 
Roll/Pitch/Yaw 
Roll / Pitch / Yaw sequentially rotates around the X / Y / Z of the 
selected coordinate system (base coordinate system). 
The following describes the roll/pitch/yaw orientation 
representation of {B} relative to {A}: 
For example, the coordinate system {B} and a known reference 
coordinate system {A} are first superposed. First rotate {B} around

by γ, then around  by β, and finally around  by α. 
Each rotation is around a fixed axis of the reference coordinate 
system {A}. This method is called the XYZ fixed angle coordinate 
system, and sometimes they are defined as the roll angle, pitch 
angle, and yaw angle. 
The above description is shown in the following figure: 
The equivalent rotation matrix is:
