User coordinate system
The user coordinate system is a movable coordinate system which is used for representing
equipment like fixtures, workbenches. The origin and the orientations of axes can be defined based
on the site requirements to measure point data within the workspace and arrange tasks conveniently.
The default user coordinate system is determined based on the robot base, as shown in Figure 4.2.
X-axis: perpendicular to the base (positive direction: forward).
Y-axis: perpendicular to the base (positive direction: left).
Z axis: vertical upward according to the right-hand rule.
