FANUC Example Programs

You are viewing an old version of the documentation. You can switch to the documentation of the latest version by clicking the top-right corner of the page.

This topic introduces the example programs that perform an actual pick-and-place task.

Prerequisites

You have set up the Standard Interface communication.
You have completed the hand-eye calibration by referring to the section FANUC Automatic Calibration.
Mech-Vision and Mech-Viz projects are created and set to autoload.
You have defined a robot TCP.
The robot velocity is set to a low value, so that the operator can notice any unexpected behavior before accidents occur.

Example Programs

The example programs are stored in Mech-Center/Robot_Interface/FANUC/sample in the installation directory of Mech-Vision & Mech-Viz.

Program Logic

Move the robot to HOME position.
Move the robot to the image-capturing pose.
Initialize communication with MM_INIT_SKT.
If parameter recipes are used in the Mech-Vision project, the recipe to be used is set with MM_SET_MOD.
Run the Mech-Vision project with MM_START_VIS.
Wait for one second. In the Eye To Hand setup, this WAIT instruction is not needed if there are motion steps between MM_START_VIS and MM_GET_VIS. In the Eye In Hand setup, this WAIT instruction is required to make sure the robot stays still until image acquisition is completed.
Obtain the vision point from Mech-Vision.
Check if the returned status code indicates any error. If an error code is returned, the program is paused.
Move the robot to the picking waypoint and perform picking.
Move the robot to an intermediate point between the picking waypoint and placing waypoint.
Move the robot to the set placing waypoint and perform placing.

Customization Required

Define the HOME position

J P[1] 100% FINE: Please set the HOME position in register P[1].
Define the TCP

UTOOL_NUM=1: Please change the tool reference frame to the one in which the actual TCP value is stored. Please change the value 1 according to the actual TCP values.
Teach the image-capturing pose

L P[2] 3000mm/sec FINE: Please record the image-capturing pose in register P[2].
Teach the intermediate point(s)

L P[3] 800mm/sec FINE: Add one or more intermediate points between the picking waypoint and placing waypoint to ensure that the robot doesn’t collide with the surrounding when moving between the picking waypoint and placing waypoint.
Teach the placing waypoint

L P[4] 200mm/sec FINE: Please record the placing waypoint in register P[4].
Define Z-offset from the picking/placing waypoint
- Approach waypoint of picking
  
  L PR[60] 800mm/sec CNT100 Offset,PR[1]: the Z-offset when approaching the picking waypoint is saved in PR[1]. This setting moves the robot to a point 100 mm above the picking waypoint. Please modify the offset value to ensure that no collisions will occur in the approaching process.
- Departure waypoint of picking
  
  L PR[60] 800mm/sec CNT100 Offset,PR[1]: the Z-offset when departing the picking waypoint is saved in register PR[1]. This setting moves the robot up 100 mm from the picking waypoint along the Z axis of the tool reference frame. Pease modify the offset value to ensure that no collisions will occur in the departing process.
- Approach waypoint of placing
  
  L P[4] 800mm/sec CNT100 Offset,PR[2]: the Z-offset when approaching the placing waypoint is saved in register PR[2]. This setting moves the robot to a point 100 mm above the placing waypoint. Please modify the offset value to ensure that no collisions will occur in the approaching process.
- Departure waypoint of placing
  
  L P[4] 800mm/sec CNT100 Offset,PR[2]: the Z-offset when departing the placing waypoint is saved in register PR[2]. This setting moves the robot up 100 mm from the placing waypoint along the Z axis of the tool reference frame. Please modify the offset value to ensure that no collisions will occur in the departing process.
Add the object picking and releasing logics for the tool

When the robot moves to the picking waypoint and the placing waypoint, you need to add the tool control logics for picking and releasing the object respectively.
