ABB Standard Interface Functions

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.

When programming the ABB robot, please pay attention to the following:

  1. Multiple parameters in a function should be separated by commas.

  2. Variable-type parameters should use local variables, which take effect only in the program.

  3. Input or Output parameters can be customized for functions.

  4. Arguments in the program: the input arguments can be constants, global variables or local variables, and the output arguments can be global variables or local variables.

The ABB Standard Interface provides the following functions.

Initialize Communication

This function sets the host IP address, port number, and wait time for TCP/IP communication.

Function

MM_Init_Socket "IP_Address",Server_Port,Time_Out;

Input Parameter

IP_Address

The IP address of the host

Server_Port

TCP/IP port number; the default port number is 50000

Time_Out

Wait time in minutes before stopping connection attempt

Example

MM_Init_Socket "192.168.1.20",50000,60;

When running the example, the host IP address should be set to 192.168.1.20, the port number should be set to 50000, and the wait time is 60 seconds.

Start Mech-Vision Project

This function is used for applications that use Mech-Vision but not Mech-Viz. This function starts the Mech-Vision project that executes image capturing and performs vision recognition.

Function

MM_Start_Vis Job,Pos_Num_Need,SendPos_Type,MM_J;

Input Parameter

Job

Mech-Vision project ID, which can be viewed before the project name in the Project List panel in Mech-Vision.

Pos_Num_Need

The expected number of vision points for Mech-Vision to send. The vision point contains the vision pose, corresponding point cloud, label, scaling, etc.

  • 0: The sender expects to receive all vision points in the recognition result from the Mech-Vision project.

  • Integer greater than 0: The sender expects to receive the specified number of vision points in the recognition result from the Mech-Vision project.

    • If the total number of vision points is less than the parameter value, all vision points in the recognition result will be sent.

    • If the total number of vision points is greater than or equal to the parameter value, the specified number of vision points will be sent.

  • The command used to obtain the vision points is command 102. Command 102 can only fetch at most 20 vision points at a time.

  • One of the returned parameter of command 102 indicates if all the requested vision points have been obtained. If not, please execute command 102 repeatedly.

SendPos_Type

The type of the robot pose to be sent to Mech-Vision. Value range: 0–3

  • 0: No robot poses need to be sent to the vision system. If the camera is mounted in the Eye To Hand mode, the image capturing process is independent of the robot pose, and therefore the robot pose is not needed.

  • 1: The robot pose in the current joint positions together with the current flange pose will be sent to the vision system. It is recommended to set this value when the camera is mounted in the Eye In Hand mode. When this parameter is set to this value, the “Path Planning” Step in the Mech-Vision project will use the joint positions sent by the robot. If the flange pose data are all 0, the vision system ignores the flange pose data.

  • 2: The robot pose in the current flange pose will be sent to the vision system. It is recommended to set this value when the camera is mounted in the Eye In Hand mode or in other scenarios where only the flange pose data is available (such as truss robots).

  • 3: The robot pose in the joint positions defined by the user will be sent to the vision system. It is recommended to set this value when the camera is mounted in the Eye To Hand mode. When this parameter is set to this value, the “Path Planning” Step in the Mech-Vision project will use the joint positions sent by the robot as the initial pose.

MM_J

User-defined joint positions. When the value of SendPos_Type is set to 3, this set of joint positions will be used as the first waypoint in the path planned by the “Path Planning” Step in the Mech-Vision project. If the value of SendPos_Type is set to values other than 3, the joint positions set here will not take effect, but it has to be set.

Example

MM_Start_Vis 1, 1, 1,MM_J

This example triggers the Mech-Vision project whose ID is 1 to run; the Mech-Vision project is expected to send back one vision point; and the robot sends its current joint positions and flange pose as the image-capturing pose to Mech-Vision.

Get Vision Target(s)

This function should be used after executing the “Start Mech-Vision Project” function. It obtains the vision result, which contains the robot pose (in TCP format) and label, from the corresponding Mech-Vision project.

Mech-Center will automatically convert the vision point information into the corresponding robot TCP. The process includes the following steps:

  • Rotate the poses around their X axes by 180 degrees.

  • Determine whether the definition of the reference frame used by the robot model involves robot base height, and add a vertical offset accordingly.

By default, command 102 can only fetch at most 20 TCPs at a time. Therefore, command 102 may need to be repeatedly executed until all the TCPs required are obtained.

Function

MM_Get_VisData Job,Last_Data,Pos_Num,MM_Status;

Input Parameter

Job

Mech-Vision project ID, which can be viewed before the project name in the Project List panel in Mech-Vision.

Output Parameter

Last_Data

This parameter indicates whether all TCPs requested have been obtained. The value is 0 or 1.

  • 0: NOT all required TCPs have been sent (more on the way). Please execute command 102 repeatedly until the value turns to 1.

  • 1: All required TCPs have been sent.

If the expected number of TCPs set in “Start Mech-Vision Project” function is greater than 20 (default value length for sending and receiving data), this parameter can be used to determine whether there is any TCP that has not been sent. If not all data have been sent, you can call command 102 repeatedly until all TCPs have been received.

If not all TCPs have been received, and command 101 is called to re-capture an image at this time, the unreceived TCPs will be cleared.

Variable type: num

Pos_Num

The number of received TCPs.

  • If the required number of TCPs is greater than or equal to the number of vision points recognized by Mech-Vision, the number of recognized vision points will be sent.

  • If the required number of TCPs is less than the number of the recognized vision points, the required number of vision points will be sent.

Value range: 0–20

Variable type: num

MM_Status

If there is no error, status code 1100 will be returned. Otherwise, the corresponding error code will be returned.

When calling this function, Mech-Center will wait for the result from Mech-Vision and then send it to the robot. The default wait time is 10 seconds. If a timeout occurs, a timeout error code will be returned to the robot.

Variable type: num

Example

MM_Get_VisData 1,LastData,PoseNum,MMStatus;

This example obtains the vision result from Mech-Vision project whose ID is 1. Whether all TCPs have been sent is stored in LastData, the number of TCPs received is stored in PoseNum, and the status code is stored in MMStatus.

0: No robot poses need to be sent to Mech-Viz. The simulated robot in Mech-Viz will start from joint positions [0,0,0,0,0,0] and move to the first waypoint.

1: The current joint positions and flange pose of the real robot need to be sent to Mech-Viz. The simulated robot in Mech-Viz will start from the current joint positions of the real robot and move to the first waypoint.

2:The predefined joint positions of the robot need to be sent to Mech-Viz. The simulated robot in Mech-Viz will start from the predefined joint positions and move to the first waypoint.

When the scene contains object models that obstruct the robot to move from [0, 0, 0, 0, 0, 0] to the first waypoint, this parameter must be set to 1.

MM_J

User-defined joint positions. User-defined joint positions. When the value of SendPos_Type is set to 2, this set of joint positions will be used as the first waypoint in the path planned by Mech-Viz. If the value of SendPos_Type is set to values other than 2, the joint positions set here will not take effect, but it has to be set.
