Regular Picking

Selected by default to send waypoint poses to the receiver, such as the robot. When this option is unselected, the waypoint pose will not be sent. However, the waypoint will remain in the planned path.

Unselected by default. When non-move Steps, such as Vision Look, Set DO, Check DI, etc., are connected between move-type Steps, the robot’s path planning will be interrupted, and the actual robot will take a short pause, reducing the smoothness of running.

When this option is selected, the project will continue to run without waiting for the current move-type Step to complete execution, and therefore the robot can move in a smooth way without pauses. However, enabling this option may cause the execution of the Step to end prematurely.

Why will this option cause the execution of the Step to end prematurely?

Mech-Viz will send multiple poses simultaneously to the robot when the project is running. When the currently returned JPs of the robot correspond to the last pose sent by Mech-Viz, Mech-Viz will assume that the robot has moved to the last position.

For example, there are 10 move-type Steps in a path, and the pose of the 5th move-type Step is the same as that of the last move-type Step. When the robot moves at low speed, it sends JPs to Mech-Viz when it moves to the 5th move-type Step, Mech-Viz may mistakenly determine that the robot has finished the move-type Steps and prematurely ends the Steps since the poses of the 5th move-type Step and the last move-type Step are the same in the path.

Unselected by default, namely that the collision with the already placed objects will not be detected. When this option is selected, the collisions between the robot, end tool, and placed objects will be detected.

In palletizing scenarios, the two possible cases of error are as follows:

When this option is selected, no collision between the robot, end tool, and the placed object will be detected, and the above two cases of errors can be avoided.

Select the proper mode according to the requirement of the on-site situation. Usually, the default setting Auto can be used. Do not check collision mode can be used in move-type Steps before the robot picks the object, and Check collision mode can be used after the robot picks the object.

This parameter will only take effect when Waypoint type of the Step is set to Workobject pose.

Once this parameter is selected, a “Plan failure” exit port will be added to the Step.

During the planning process, planning is carried out along the branch after the “Success” exit port. If the planning fails in the current Step, the branch process after the “Planning failure” exit port will be executed.

Unselected by default. Once this option is selected, the collisions between the held workobject with the scene objects or robot will not be detected, and therefore the calculation workload of collision detection will be reduced, the planning speed can be increased, and the cycle time can be shortened. It is usually enabled in the first one or two move-type Steps after the robot picks the object.

Please enable this option cautiously as there may be collision risks.

When Detect collision between held workobject and others under Collision detection configuration  Configuration on held workobject is enabled, the software will detect whether the model of the held object collides with the models of the scene objects and the robot.

In palletizing projects, the calculated carton dimensions have millimeter-level errors with the actual dimensions, and frictions between cartons may occur during picking but no collisions will occur. For some move-type Steps that will obviously not cause collisions, detecting such collisions only adds to the calculation workload and planning time, and consequently extending the cycle time. In palletizing projects, enabling Do Not Check Collision with Scene Objects does not affect the collision detection between the held carton and the placed cartons. This option can be enabled when there are scene objects under the stack to avoid failure of finding the palletizing solution.

Unselected by default. Once this option is selected, the collisions between the held workobject with the point clouds in the scene will not be detected, and therefore the calculation workload of collision detection will be reduced, the planning speed can be increased, and the cycle time can be shortened.

Usually, Vision Move will only use one pose of the corresponding vision result. However, once this parameter is selected, the robot will move through all waypoints corresponding to the vision poses at one time.

This parameter is usually used when the robot moves in a fixed path where no DO signals will be sent, such as the gluing application.

When this feature is not enabled, each time “Vision Move” plans a robot picking path successfully, the rest unused vision results will be discarded. If this feature is enabled, the vision result that leads to a planning failure and the rest unused vision results will be retained and used for the next planning. This feature should be used with the “Is Vision Result Used Up” Step.

When there are multiple pickable objects in one vision result and it can be guaranteed that picking one object will not affect the poses of other objects, this option can be selected. The vision result will be reused and no new image will be captured until all vision results are used up.

Application Example

This feature enables multiple “Vision Move” Steps in which the same vision service is selected to share the vision result.

When one “Vision Move” Step plans successfully, the corresponding vision result will be used, and the unused vision result will be used by the next “Vision Move” Step with this feature enabled. After all “Vision Move” Steps that share the vision result complete planning, the rest results will be discarded.

In addition, this feature can be used in conjunction with the “Reuse Vision Result” feature. When “Reuse Vision Result” is selected, the rest vision results will not be discarded even after all “Vision Move” Steps have completed one round of planning.

Once the Update Bin Pose with Vision parameter is selected, the bin will be recognized and located simultaneously while the camera captures the image for target object recognition. Therefore, the bin pose in the simulation area can be updated dynamically, which facilitates the collision detection algorithm to effectively prevent the robot from colliding with the bin.

This feature will provide three fields, scene_object_names, scene_object_poses, and scene_object_sizes, in the vision result to define the name, pose, and dimensions of the scene object to be updated.

This parameter group is mainly used to avoid picking on the same pick point in scenarios where the object cannot be picked successfully.

Once the Filter Out Unlikely Pick Point parameter is selected, you can adjust the following parameters.

Select Limit Total Count and you can set the maximum Planned Count and other parameters.
