Start Mech-Viz Project

In scenarios where both Mech-Vision and Mech-Viz are used, this function starts the Mech-Viz project that triggers the corresponding Mech-Vision project, and therefore the Mech-Viz project can plan the robot path based on the vision points received from Mech-Vision.

Unnamed image

Parameters

Input Parameters:

  • Robot_Pose_Type: The type of robot pose to input to Mech-Viz. The value range is 0–2.

  • Robot_Pose_JPS: Current joint positions of the robot. The data type is one-dimensional Array[0..5] of DInt.

  • Robot_Pose_TCP: Current flange pose of the robot. The data type is one-dimensional Array[0..5] of DInt.

The following table explains the relationship between Robot_Pose_Type and Robot_Pose_JPS/Robot_Pose_TCP.

Robot_Pose_Type Robot_Pose_JPS Robot_Pose_TCP Description Applicable Scenarios

0

0, 0, 0, 0, 0, 0

0, 0, 0, 0, 0, 0

No need to input robot pose to Mech-Viz. The simulated robot in Mech-Viz moves from JPs = [0, 0, 0, 0, 0, 0] to the first waypoint.

Project is in the eye-to-hand mode. This setting is not recommended.

1

Current joint positions of the robot

Current flange pose of the robot

Robot JPs and flange pose must be input to Mech-Viz. The simulated robot in Mech-Viz moves from the input JPs to the first waypoint.

This setting is recommended for projects in the eye-in-hand mode.

2

Specific JPs of the robot

0, 0, 0, 0, 0, 0

The robot JPs of a point determined by teaching must be input to Mech-Viz. The input JPs are used to trigger Mech-Viz 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 JPs to the first waypoint.

This setting is recommended for projects in the eye-to-hand mode.

The reason for setting robot pose type to 2 when the project is in the eye-to-hand mode: In the eye-to-hand mode, the camera can perform image capturing for the next round of path planning before the robot returns to the camera capture region and picking region, shortening the cycle time. If Robot_Pose_Type is set to 1, the robot’s current pose is sent to Mech-Viz. The simulated robot will move from the input pose to the first waypoint in the planned path, while the real robot might move to another point first, and then move to the first waypoint. Therefore, the path of the real robot may contain unpredicted collisions, leading to safety hazards. In conclusion, robot pose type should be set to 2 for projects in the eye-to-hand mode.
