Description
Product Specification IRB 4400 M98A/BaseWare OS 3.2
17
The base coordinate system is attached to the base mounting surface of the robot.
The tool coordinate system specifies the tool’s centre point and orientation.
The user coordinate system specifies the position of a fixture or workpiece
manipulator.
The object coordinate system specifies how a workpiece is positioned in a fixture or
workpiece manipulator.
The coordinate systems can be programmed by specifying numeric values or jogging
the robot through a number of positions (the tool does not have to be removed).
Each position is specified in object coordinates with respect to the tool’s position and
orientation. This means that even if a tool is changed because it is damaged, the old
program can still be used, unchanged, by making a new definition of the tool.
If a fixture or workpiece is moved, only the user or object coordinate system has to be
redefined.
Stationary TCP
When the robot is holding a work object and working on a stationary tool, it is possible
to define a TCP for that tool. When that tool is active, the programmed path and speed
are related to the work object.
Program execution
The robot can move in any of the following ways:
- Joint motion (all axes move individually and reach
the programmed position at the same time).
- Linear motion (the TCP moves in a linear path).
- Circle motion (the TCP moves in a circular path).
Soft servo - allowing external forces to cause deviation from programmed position -
can be used as an alternative to mechanical compliance in grippers, where imperfection
in processed objects can occur.
If the location of a workpiece varies from time to time, the robot can find its position
by means of a digital sensor. The robot program can then be modified in order to adjust
the motion to the location of the part.
Jogging
The robot can be manually operated in any one of the following ways:
- Axis-by-axis, i.e. one axis at a time.
- Linearly, i.e. the TCP moves in a linear path (relative to one of the coordinate
systems mentioned above).
- Reoriented around the TCP.
