FANUC Standard Interface Commands

This section describes standard interface commands used in TCP communications between a FANUC robot and Mech-Mind Vision System. The robot (the client) sends commands to Mech-Mind Vision System (the server), and Mech-Mind Vision System returns the processed data to the robot.

send receive

Before you call the commands, take note of the following items:

  • Unit of data:

    • The unit of joint positions is degree (°).

    • A robot’s flange pose or TCP consists of the position and pose. The position is represented in XYZ coordinates and is measured in millimeters (mm); the pose is represented in Euler angles and is measured in degrees (°).

  • Vision point and waypoint:

    • Vision point: An object recognized by Mech-Vision. A vision point has information including the object pose, label, velocity, dimensions, and custom port output data.

    • Waypoint: Each point that the robot reaches when moving along the planned path. A waypoint has information including the robot pose, label, motion type, and velocity. Waypoints can be divided into two categories:

      • Vision Move waypoints, which refer to the waypoints corresponding to the Vision Move Step.

      • Non-Vision Move waypoints, which refer to the waypoints corresponding to Move-type Steps other than the Vision Move Step.

Initialize Communication

Command

This command establishes the TCP communication between the robot and the vision system.

Command Format

MM_INIT_SKT(C_Tag,Ip_Addr,Svr_Port,Time_Out)

Input Parameters

C_Tag

This parameter specifies the string-typed robot port number. Valid values: 1 to 8.

Ip_Addr

This parameter specifies the string-typed IP address of the IPC.

Svr_Port

This parameter specifies the port number used by the IPC to establish the communication between the IPC and the robot. This port number must be consistent with the host port number that is specified for robot communication in the toolbar of Mech-Vision.

Time_Out

This parameter specifies the communication timeout period. Unit: minutes.

Example

CALL MM_INIT_SKT('1','192.168.1.20',50000,5)

In this example, the IP address of the IPC to which you want to connect the robot is 192.168.1.20, the port number is 50000, and the timeout period is 5 minutes.

Run Mech-Vision Project

Command

This command triggers the Mech-Vision project to run. When the Mech-Vision project is running, the vision system triggers the camera to capture images and then process the returned images with algorithms to produce a series of vision points or waypoints.

  • Vision point: An object recognized by Mech-Vision. A vision point has information including the object pose, label, velocity, dimensions, and custom port output data.

  • Waypoint: Each point that the robot reaches when moving along the planned path. A waypoint has information including the robot pose, label, motion type, and velocity.

Calling Sequence

Command Format

MM_START_VIS(Job,Pos_Num_Need,SendPos_Type,Pr_Num)

Input Parameters

Job

This parameter specifies the Mech-Vision project ID. You can view the project ID of a Mech-Vision project in the Project List section of Mech-Vision. The project ID is the number before the project name.

Pos_Num_Need

This parameter specifies the expected number of vision points or waypoints to be obtained from the Mech-Vision project. Value range: 0 to the largest positive integer.

If the Mech-Vision project has a Path Planning Step, this parameter specifies the expected number of waypoints. Otherwise, it specifies the expected number of vision points.
  • 0: Obtain all vision points or waypoints from the Mech-Vision project.

  • A positive integer: Obtain the specific number of vision points or waypoints from the Mech-Vision project.

    • If the total amount of vision points or waypoints output by the Mech-Vision project is smaller than the parameter value, this command will obtain the number of all vision points or waypoints.

    • If the total amount of vision points or waypoints output by the Mech-Vision project is larger than or equal to the parameter value, this command will obtain the number of vision points or waypoints as specified by this parameter.

  • Vision points or waypoints will not be returned after Run Mech-Vision Project is called. To obtain vision points, call Get Vision Result or Get Mech-Vision Custom Output Data. To obtain waypoints, call Get Planned Path in Mech-Vision.

  • The default maximum number of vision points or waypoints that the vision system sends at a time is 20. To modify the default maximum number of poses to obtain each time as needed, go to Robot Communication Configuration  Next  Advanced Settings in the toolbar of Mech-Vision. The upper limit is 30.

set number

SendPos_Type

This parameter specifies the way in which the real robot pose is sent to the Mech-Vision project. Valid values: 0, 1, 2, and 3. The following table describes the details.

SendPos_Type Description Applicable scenario

0

The command does not send the robot pose data to the Mech-Vision project.

This setting is recommended when the camera is mounted in the Eye To Hand method. If the Path Planning Step is used in the Mech-Vision project, the starting point of the planned path will be the Home point set in the path planning tool.

1

The robot joint positions and flange pose must be input to the Mech-Vision project.

This setting is recommended when the camera is mounted in the Eye In Hand method. Applicable for most robot types except gantry robots.

2

The robot flange pose must be input to the Mech-Vision project.

This setting is recommended when the camera is mounted in the Eye In Hand method. The robot has the flange pose but no joint positions, such as a gantry robot.

3

This command sends custom joint positions to the Mech-Vision project.

This setting is recommended when the camera is mounted in the Eye To Hand method, and the Mech-Vision project contains the Path Planning Step, whose starting point needs to be set at the robot side.

Pr_Num

This parameter specifies the position register ID. The position register that corresponds to the ID stores custom joint position data.

  • If the SendPos_Typeparameter value is 3, the joint positions represented by the position register here will be sent to the “Path Planning” Step of the Mech-Vision project for planning as the first waypoint. In this case, the data type of the position register must be modified to the joint position type.

  • If SendPos_Type is set to a parameter value other than 3, the joint position data is of no practical use but the position register ID must be set.

Example

CALL MM_START_VIS(1,1,1,60)

In the preceding example, the Mech-Vision project whose ID is 1 is run, and one vision point is expected to be returned by the Mech-Vision project. At the same time, the robot sends the current joint position and flange pose data to the Mech-Vision project.

Get Vision Result

Command

This command obtains vision result, namely, a series of vision points, from Mech-Vision. The object pose of the vision point (namely, the output of the poses port of the Procedure Out Step) will be automatically converted to the robot’s TCP by the vision system. The process is as follows.

get tcp
  1. Convert the object pose from a quaternion to Euler angles.

  2. Rotate the object’s pose around the X-axis by 180° to orient its Z-axis downward.

    convert tcp
  3. Add the vertical offset to fit the base point defined by the robot manufacturer.

Right-click the project name in the project resource panel in Mech-Viz and select Autoload Project.

Calling Sequence

You should set Step parameters before starting a Mech-Viz project. Therefore, call Read Mech-Viz Step Parameter or Set Mech-Viz Step Parameter before calling Run Mech-Viz project.

Command Format

MM_START_VIZ(SendPos_Type,Pr_Num)

Input Parameters

SendPos_Type

This parameter specifies the way in which the real robot pose is sent to the Mech-Viz project. Valid values: 0, 1, and 2. The following table describes the details.

Robot pose type Description Applicable scenario

0

The command does not need to send the robot pose to the Mech-Viz project. The simulated robot in Mech-Viz moves from the initial pose (joint positions = [0, 0, 0, 0, 0, 0]) to the first waypoint.

This setting is recommended when the camera is mounted in the Eye To Hand method.

1

In this command, the robot sends its current joint positions and flange pose to the Mech-Viz project. The simulated robot in Mech-Viz moves from the input joint positions to the first waypoint.

This setting is recommended when the camera is mounted in the Eye In Hand method.

2

In this command, the robot sends the joint positions of a teaching point (the custom joint positions), instead of the current joint positions, to the Mech-Viz project. The Mech-Viz project uses the joint positions to plan the next path in advance while the robot is not in the camera capture region, as shown below. The simulated robot in Mech-Viz moves from the input joint positions to the first waypoint.

This setting is recommended when the camera is mounted in the Eye To Hand method.

Why robot pose type 2 is recommended when the camera is mounted in the Eye To Hand method?

In the Eye To Hand method, the camera can perform image capturing for the next round of path planning before the robot returns to the image capture region and picking region, thus shortening the cycle time. The image below demonstrates how a robot works in the placing region.

If SendPos_Type is set to 1, the robot will send the current pose to Mech-Viz. It is possible that the real robot moves to other positions before reaching the first waypoint. However, the simulated robot moves directly to the first waypoint of the Mech-Viz project from the pose sent by the robot. Consequently, there may be a mismatch between the paths of the real robot and simulated robot. This mismatch can potentially lead to unpredicted safety hazards, especially if collision is detected in the path of the simulated robot.

On the other hand, if SendPos_Type is set to 2, the robot will send the image-capturing pose set by teaching to Mech-Viz. Thus, the real robot can trigger the next round of path planning in Mech-Viz when the real robot is in the image-capturing region and the cycle time can be shortened.

In conclusion, robot pose type should be set to 2 for projects in the Eye To Hand method.

robot example

Pr_Num

This parameter specifies the position register ID. The position register that corresponds to the ID stores custom joint position data.

  • If the SendPos_Typeparameter value is 2, the joint positions represented by the position register here will be sent to the Mech-Viz project for planning as the first waypoint. In this case, the data type of the position register must be modified to the joint position type.

  • If SendPos_Type is set to a parameter value other than 2, the joint position data is of no practical use but the position register ID must be set.

Example

CALL MM_START_VIZ(1,60)

In the preceding example, the joint position data and flange pose of the robot are input to the Mech-Viz project for the Mech-Viz project to run.

set index

Calling Sequence

Index-type Steps are often preceded by a Branch by Msg Step. The robot should call commands in this order: Run Mech-Viz project, Set Current Index in Mech-Viz, and Set Exit Port for Branch by Msg Step in Mech-Viz. This is to ensure that Mech-Viz has enough time to set the Current Index value.

Command Format

MM_SET_IDX(Skill_Num,Index_Num)

Input Parameters

Skill_Num

  • Vision Move waypoints, which refer to the waypoints corresponding to the Vision Move Step.

  • Non-Vision Move waypoints, which refer to the waypoints corresponding to Move-type Steps other than the Vision Move Step.

Calling Sequence

This command should be called after Run Mech-Viz project. After you call this command, call Store vision result or planned path (TCP-typed pose data) or Store Planned Path (joint position-typed pose data) to access pose data.

Command Format

MM_GET_VIZ(Jps_Pos,Reg_Pos_Num,Reg_VPos_Num,Reg_Status)

Input Parameters

Jps_Pos

This parameter specifies the type of waypoint poses to be obtained. The parameter value can be set to 1 or 2.

Output Parameters

Reg_Pos_Num

This parameter specifies the ID of the numeric register. The numeric register that corresponds to the ID stores the number of waypoints returned by the vision system. By default, the vision system sends no more than 20 waypoints at a time. Therefore, the maximum default value of this parameter is 20. To modify the default maximum number of poses to obtain each time as needed, go to Robot Communication Configuration  Next  Advanced Settings in the toolbar of Mech-Vision. The upper limit is 30.

set number

Reg_VPos_Num

This parameter specifies the ID of the numeric register. The numeric resister corresponding to the ID stores the position ID of the Vision Move waypoint that corresponds to the Vision Move step in the Mech-Viz project in the path. If the waypoint does not exist in the path, the petameter value is 0.

If the planned path consists of the following waypoints in sequence: Fixed-Point Move_1, Fixed-Point Move_2, Vision Move, and Fixed-Point Move_3, the position ID of the Vision Move waypoint is 3.

Reg_Status

This parameter specifies the ID of the numeric register. The numeric register that corresponds to the ID stores the status code of this command. If the command is successfully executed, the status code is 2100. If a command fails to be called, a specific error code is returned. For details, see Status Codes and Troubleshooting.

By default, after the robot sends this command, the vision system returns the result in 10 seconds. If the vision system fails to return any result in 10 seconds, a timeout error code is returned. To modify the default timeout period as needed, go to Robot Communication Configuration  Next  Advanced Settings in the toolbar of Mech-Vision.
