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.

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

Communication Initialization

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-type robot port number. Valid values: 1 to 8.

Ip_Addr

This parameter specifies the string-type 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 that you want to connect to 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, dimensions, and custom data.
Waypoint: Each point that the robot reaches when moving along the planned path. A waypoint has information including the robot pose, label, and motion type.

Calling Sequence

You should set Step parameters before starting a Mech-Vision project. Therefore, call Switch Mech-Vision Parameter Recipe or Input Object Dimensions to Mech-Vision Project before calling Run Mech-Vision Project.
Vision system gets vision points and waypoints only after a Mech-Vision project runs. Therefore, call Run Mech-Vision Project before calling Get Vision Result, Get Planned Path in Mech-Vision, or Get Mech-Vision Custom Data.

Command Format

MM_START_VIS(Job,Pos_Num_Need,SendPos_Type,Pr_Num)

Input Parameters

Job

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 indicates the expected number of waypoints. Otherwise, it indicates 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 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 and Communication > Robot Communication Configuration Next Advanced Settings in the toolbar of Mech-Vision. The upper limit is 30.

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 start 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 start point needs to be set at the robot side.

SendPos_Type

Description

Applicable scenario

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 start point of the planned path will be the Home point set in the path planning tool.

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.

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.

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 start 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 that is represented by the position register 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 Output Step) will be automatically converted to the robot’s TCP by the vision system. The process is as follows.

Convert the object pose from a quaternion to Euler angles.
Rotate the object’s pose around the X-axis by 180° to orient its Z-axis downward.

This command should be called before Set Gripper DO List.

Command Format

MM_GET_DL(Resource,Block_Num)

Input Parameters

Resource

This parameter specifies the source of the DO signal list. Value range: 0 to the largest positive integer.

0: Get DO signal list from Mech-Viz.
A positive integer: Get DO signal list from Mech-Vision. The positive integer is the Mech-Vision project ID.

The DO signals returned by this command vary based on the deployed project.

Gripper DO signals planned by the Mech-Vision project

Under Global Configuration of the path planning tool, if Plan all vision results is disabled, this command returns 64 gripper DO signals that are planned in this round. Valid DO signals are non-negative integers ranging from 0 to 999. Invalid DO signals are -1, which serves as a placeholder.

For example, valid DO signals in the table below are 1, 3, 5, and 6, which means that the robot will set the values of these DO signals to ON.

Under Global Configuration of the path planning tool, if Plan all vision results is enabled, Mech-Vision can perform multiple rounds of planning based on the same vision result. The 64 gripper DO signals returned by this command are obtained during all rounds of planning. In this case, you can use the number of vacuum gripper sections to differentiate the gripper DO signals obtained during each round of planning.

For example, if the number of vacuum gripper sections is 4 and the command returns 64 DO signals in total, each 4 DO signals are multi-section vacuum gripper signals obtained during each round of planning.

First round of planning				Second round of planning				…	16th round of planning
1st	2nd	3rd	4th	5th	6th	7th	8th	…	61st	62nd	63rd	64th
1	3	4	-1	1	4	-1	-1	…	-1	-1	-1	-1

Gripper DO signals planned by the Mech-Viz project

If Reuse Vision Result is not selected for the Vision Move Step, this command returns 64 gripper DO signals that are planned during this round. Valid DO signals are non-negative integers ranging from 0 to 999. Invalid DO signals are -1, which serves as a placeholder.

For example, valid DO signals in the table below are 1, 3, 5, and 6, which means that the robot will set the values of these DO signals to ON.

If Reuse Vision Result is selected for the Vision Move Step and the Vision Move Step is used in a loop, Mech-Viz can perform multiple rounds of planning based on the same vision result. The 64 gripper DO signals returned by this command are obtained during all rounds of planning. In this case, you can use the number of vacuum gripper sections to differentiate the gripper DO signals obtained during each round of planning.

Command

This command triggers the Mech-Viz project to run. Mech-Viz plans the robot’s motion path based on the vision result output by Mech-Vision.

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 teach 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.

Robot pose type

Description

Applicable scenario

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.

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.

In this command, the robot sends the joint positions of a teach 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 teach 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.

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 that is represented by the position register 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 Exit Port for Branch by Msg Step in Mech-Viz

Command

This command sets the exit port for the Branch by Msg Step. When the next Step is a Branch by Msg Step, the Mech-Viz project will wait for this command to specify the exit port.

Calling Sequence

This command should be called after Run Mech-Viz Project.

Command Format

MM_SET_BCH(Branch_Num,Export_Num)

Input Parameters

Branch_Num

This parameter specifies the Step ID of the Branch by Msg Step. The value is a positive integer. The Step ID is displayed in the Step parameter panel. For example, the Step ID of the Step in the image above is 1.

Export_Num

This parameter specifies the exit port ID of the Branch by Msg Step. The value is a positive integer. When the parameter value is set to N, the Mech-Viz project exits from the port with an ID of N-1 of the Branch by Msg Step.

CALL MM_SET_BCH(1,3)

In the preceding example, the Mech-Viz project with an ID of 1 exits from the port with an ID of 2 of the Branch by Msg Step.

Set Current Index in Mech-Viz

Command

This command sets the value of the Current Index parameter of index-type Steps. Steps that include the Index section include Move by Grid, Move by List, Custom Pallet Pattern, and Predefined Pallet Pattern.

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

This parameter specifies the Step ID of the Index-type Step. The value is a positive integer. The Step ID is displayed in the Step parameter panel. For example, the Step ID of the Step in the image above is 3.

Index_Num

This parameter specifies the current index for a Index-type Step. The value is a positive integer. When this parameter value is set to N, the current index of the corresponding Step is N-1.

Example

Command

This command obtains the path planned by the Mech-Viz project as a series of waypoints.

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

Vision Move waypoint: Waypoint 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) or Store Planned Path (joint positions) 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. can be set to 1 or 2.

1: joint positions. After you run this command, run Store Planned Path (joint positions) to access joint position data.
2: tool poses. After you run this command, run Store Vision Result or Planned Path (TCP) to access tool pose data.

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 and Communication > Robot Communication Configuration Next Advanced Settings in the toolbar of Mech-Vision. The upper limit is 30.

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 run, a specific error code is returned. For details, see Status Codes and Troubleshooting.
