Objects

Object Placement

To place a new object in the cell, do the following:

1. Double click on the object’s name in the New Objects menu.

2. Move the cursor into the graphic scene.

3. Point and click on the location where you want to place the object. You may need to wait a moment for it to appear; do not double click.

If you have trouble placing an object in the exact spot you want, zoom in and out, and adjust the view from top to bottom until you can more accurately place the object.

Most objects are placed in the cell automatically at table level. These objects will appear to float in space unless a table has also been placed in the cell.

The height of some objects (template, jig, cylinder and cube) is determined at the time they are placed in the cell.

If, for example, you click on the conveyor when placing a cube in the scene, the cube will be placed on the conveyor at the proper height.

It is recommended that a table be placed in the cell before any of these four objects is added to the cell. Otherwise, these objects may be set on the cell floor and are hidden when a table is added.

RoboCell

0311

20 User Manual

CellSetup

Once an object’s height is set, it cannot be changed in CellSetup. For example, you cannot move the cube from the table onto the conveyor.

Moving an object whose height has been set will cause it to float in space or penetrate another object. If the setup is saved with a floating object, the object will fall to the surface below it when the file is loaded in RoboCell.

To change an object’s height in CellSetup, you must delete the object and create a new one.

To move an object, simply click on it and drag it to another position. Or use the object’s properties menu to set precise position coordinates.

The robot cannot be dragged to another position. Its position can be changed only by means of its properties menu.

Object Configuration

Selecting some of the objects from the New Object list will open a configuration dialog box for defining the object’s permanent attributes (such as size and color). Attributes must be set before an object can be placed in a cell.

An object’s configuration cannot be changed once the object has been placed in the cell. You must delete the original object, and select and configure the object again from the New Object list.

Objects that have configuration options are described later in this section.

Object Properties Menu

Double clicking on an object that has already been placed in the cell opens the Object Properties menu.

Object properties can be changed at any time during cell setup.

All Object Properties menus contain the object’s name and the following options. Some objects have additional properties which are described in the individual sections.

Rename

Every object is automatically assigned a name and a number when it is placed in the cell. This name is displayed in the object’s properties menu.

The number indicates the order in which objects of the same type were added to the cell (e.g.,

FEEDER1, GFEEDER2).

Clicking on Rename opens a dialog box that allows you to change the name of the object. The number can be changed or deleted.


CellSetup

Rotate

Position

Show Text

Objects can be rotated to any degree, in the minus

(clockwise) or plus (counterclockwise) direction.

Clicking on Rotate opens a dialog box that allows you to change the object’s orientation.

The degree of rotation is always defined relative to the object's default (predefined) orientation.

The cell has a point of origin at table level defined by XY coordinates (0,0). All object positions are defined in XY coordinates relative to this point of origin.

For most objects these XY coordinates indicate the center of the object’s base.

By default, the robot is placed in the cell with the center of its base (i.e., the robot's point of origin) at the cell’s point of origin.

Clicking on Set Position opens a dialog box that allows you to change an object’s X and/or Y coordinates.

Shows/hides the label for the selected object.

This option can only be activated when View |

Object Names or View | Object Positions is selected.

New Objects Menu

New objects are added to the cell using the New Objects menu. The objects are arranged in groups (robots, peripheral axes, etc.).

To add a new object to the cell, click on the desired object group

(folder) and then select the specific object. The groups are detailed below.

Robots

Alternatively, these slidebase options are available:

•

•

Slidebase 1.0 m, belt drive

Slidebase 1.8 m, belt drive

If you select a slidebase, the Robot Configuration dialog box looks like this:

Figure 4-6: Robot Configuration


CellSetup

Properties tab:

LSB Height By default, the LSB Height is 100 mm, which is the actual height of standard SCORBOT slidebases.

Robot Angle By default, the robot is mounted perpendicular to the slidebase at 90º.

If you select a slidebase, the robot and the slidebase are treated as one object in the cell.

Peripherals tab:

To select a controller peripheral axis that controls the slidebase (and any other peripheral device that has already been defined), click on the

Peripherals tab.

Figure 4-7: Axis Selection for Peripherals

Peripheral devices can be connected either to axis 7 or to axis 8. To connect a device listed under Not connected, click on it and drag it to one of the free controller axes. If you drag the device to an axis that already has a connected device, the new device replaces the previous device which is disconnected and relocated under Not connected.

Figure 4-11: Gravity Feeder

Unlike most objects, the feeder’s position is defined as the point at which the robot takes an object from the lower part of the feeder. All the remaining objects slide down the feeder to be taken in turn.

When placing objects on the gravity feeder, you must position them in the light gray section of the feeder’s mouth

(as shown by the Cursor in Figure 4-11).

Clicking with the mouse on the keys on the Manual Movement dialog box keys, or pressing keys on the keyboard, moves the virtual robot axes.

Movement of an axis continues as long as the button or key is pressed, or until a software or hardware limit is reached.

Note: In ER2, axis 6 is disabled.

Use the Open Gripper and Close Gripper buttons to control the gripper.


Cell Operation

Machine Operation

You can operate the Mill or Lathe directly from the Digital Output dialog box, or with program commands (see Program Execution). A program continues to run after the machine begins to operate.

Be sure to close the chuck on the Mill or Lathe before you open the Robot gripper to release it. A part placed in the Lathe will drop to the bottom unless the chuck is closed before opening the robot gripper.

A part placed in the Mill may fall once the Mill cycle begins, if the chuck is not closed before starting the cycle.

Mill and Lathe will work only if the door is closed.

Send Robot Commands

Send Robot commands can often be used instead of the SCORBASE Manual

Movement dialog box. Commonly, however, you will use the Manual

Movement dialog box to adjust the robot’s position after using a Send Robot command.

When SCORBASE is operating online with an actual robotic cell, the Send

Robot commands and options are disabled.

When using the Send Robot commands, be aware of certain characteristics of the following objects.

Feeders

Lathe

Click on the part in the feeder (and not the feeder itself), to select it as the target position for the

Send Robot to Object command.

To easily pick up a part from the feeder, select a pitch of 0° and a roll of (-90°) in the Send Robot

Options dialog box.

Each of the four clamps in the chuck can be a target object. You cannot use the Send Robot to

Object command to place an object in the lathe.

Object must be placed in the chuck manually.

Only cylinders can be placed in the chuck. Use the Manual Movement dialog box to position the cylinder exactly.

Although it is regarded as one object, the template is comprised of two objects, the tray and the handle, either of which can be a target object.

The template has only one position, defined by the center of the tray.

Use Z-offset 35 mm to send the robot to the template tray.

Use Z-offset 0 mm (user-defined) to send the robot to the template handle.


Cell Operation

Gripper

Grasping Objects

The robot gripper in RoboCell will grasp an object only as a result of Close

Gripper commands.

When the gripper closes on an object, the object is pushed into the center of gripper.

In addition, cubes and horizontal cylinders are rotated into alignment with the gripper jaws, provided the rotation offset does not exceed 35º. When the offset is about 45º, the gripper simply grasps the object at its corners.

Since objects are rotated around their center, a long object that will be grasped far from its center must be aligned with the gripper as much as possible before the gripper is closed.

Releasing Objects

RoboCell operates in a gravitational field. Objects that are released from the gripper will fall to the first surface below them.

If more than half of an object’s base rests on a surface, the object will remain on the surface. Otherwise it will fall onto the surface below.

Objects can be picked up and released at any rotation.

Impact Detection

RoboCell checks for the following impact conditions:

•

The tip of the gripper hits an object or the robot itself.

•

•

The edge of the gripper motor (mounted on top of the gripper) hits an object or the robot itself.

An object held by the gripper hits another object or the robot.

RoboCell’s impact error message is the same one sent by SCORBASE when an actual robot cannot reach a target position. Since there are no mechanical

(motor) or electrical (encoder) failures in simulation, you can assume simply that the gripper or an object held by the gripper has collided with the robot or another object.

The Graphic Display status line indicates the object on which the impact has occurred.

In response to the impact error message, select OK to resume Control On.

Then move the robot away from the impact condition. If a Send Robot

RoboCell

0311

54 User Manual

command caused the impact, the robot will resume movement from the position that preceded the Send Robot command.

When SCORBASE is operating online with an actual robotic cell,

SCORBASE controls impact detection and response, and Cell Simulation’s impact detection function is disabled.

Defining Positions

RoboCell provides the methods described below for defining robot positions.

A position is identified by its assigned number.

Recording Position #1

1. Use the SCORBASE Manual Movement dialog box to manipulate the virtual robot in the same manner in which you would manipulate an actual robot.

2. When the position is reached, type a number in the position number field in the Teach Position (Simple) dialog box.

3. Click Record.

If the position number has been used previously, the new position will overwrite the previous position data.

Recording Position #2

1. To send a robot to a required position, use the Send Robot to

Object/Position/Above Position tools.

2. If needed, use the Manual Movement dialog box for fine-tuning.

3. When the position is reached, type a number in the position number field in the Teach Position (Simple) dialog box.

Executing programs in RoboCell is the same as executing programs when using an actual robotic system.

Since different cell configurations can be loaded and changed in RoboCell, keep in mind that positions and programs are not loaded together with their workcell.

To use a workcell with its positions for a new project save the project with the workcell and positions under a different name, using the Save as option in the File menu.

Then delete the program and write a new one (the positions and the cell remain unchanged).

Figure 7-7: Welding Settings Dialog Box

Voltage Tap

Wire Diameter

Sets welding machine voltage output supplied to the welding gun, an important variable in determining the quality and appearance of a weld.

The voltage tap value is a reference number (and

2 does not indicate a voltage value).

The voltage tap should be set according to several factors, such as robot speed, wire speed and metal thickness.

Sets diameter of the welding wire being fed to the

MIG welding gun. Cannot be changed.

Default of wire diameter used in the AMT tekLINK is 0.023 inch.

64 User Manual

Welding Features

Wire Speed Sets speed at which the wire is fed to the MIG welding gun. Also known as feed rate.

The wire speed setting is essentially a reference value to the controller built into the welder. Valid values: 10 - 100.

The wire speed is automatically regulated by the welder for optimal performance and does not need manual input. The welder determines the feed rate setting by weighing three factors: type of shielding gas, metal thickness and wire diameter.

Shielding Gas Sets type of gas for shielding the weld from oxidation, which causes rust and poor joining of the welded pieces. The system only works with

CO

2

gas.

The default parameters are set according to the Millermatic recommended settings (see Millermatic User’s Manual).

Some parameters are interrelated. For example, changing the voltage tap causes the wire speed default to change automatically. Note that the wire speed can also be changed independently of the voltage tap.

Welding settings can also be changed by the user when working within the Graphic Display window. The settings will remain in effect for all subsequent simulated welds.

Note: Changes in this dialog box do not affect the actual Millermatic

welder settings.

This dialog box can also be accessed by double-clicking on the welding machine knobs. Note that parameter changes are reflected in the knobs’ positions.

Controller Output

Number for Welding

Machine

The welding machine operation is controlled using a controller output. After placing the welding machine (in CellSetup) you should assign a free controller output for controlling the welding machine.


Welding Features

Gun Stand

The gun stand does not require the user to define any additional configurations or properties. The user need only place it in an accessible position on the welding table. CellSetup draws the cable that connects the welding machine to the gun.

To define the rate of travel (the speed of the robot and the welding gun in the welding procedure), use the Duration setting in the Go To position dialog box.

By changing the duration it takes to get from position A (weld start position) to B (weld end position), the robot’s speed is changed – thus changing the speed at which it will weld.

Distance of Electrode from Materials to be

Welded

Angle of electrode

When recording the start/finish welding positions, you define this distance by defining the positions’ Z value.

Welding only occurs when the electrode of the welding gun is located at a proper distance above

“weldable” material. This feature was built-in to enable more accurate recording of the start welding position.

Once the software recognizes that welding is

“allowed”, the gun emits wire that creates a seam between the two materials.

Welding will not occur in the following situations:

•

•

The electrode of the welding gun is too close or too far from the material.

The welding gun is located above a material that the software recognizes as “non-weldable”.

When recording the start/finish weld positions, you define this angle by defining the positions’ pitch.


Welding Features

Welding Process

Welding Gun Operation

As welding occurs, sparks will fly from the welding gun, as shown in the figure below.

Replicating Real and

Simulated Cells

RoboCell’s representation of robot and devices are based on actual dimensions and functions of SCORBOT equipment. Thus, programming performed in RoboCell can be used with an actual robotic installation.

From Simulation to Real

Using CellSetup and Cell Simulation, create a cell, record all positions to be used by the SCORBASE program, write the SCORBASE program and verify program execution.

Then, to construct an actual robotic installation that duplicates the simulated cell:

1. Using CellSetup as a guide, place all objects and devices in their approximate locations.

2. To print a 3D Image, select File | Print 3D Image.

3. If necessary, hide some labels and/or change the angle and zoom of the camera, and print several cell maps.

4. Consider your SCORBASE program and determine which of the recorded positions must be precise; for example, the point at which the robot takes an object from a feeder, or the point at which the robot places a part in a machine.

5. In SCORBASE On-Line mode, send the robot to these key positions.

Adjust the location and orientation of the actual objects and devices

(e.g., feeder, machine) according to the location of the gripper.

If you are unable to relocate the object or device, you can rerecord the position coordinates.


Replicating Real and Simulated Cells

From Real to Simulation

To create a simulated cell based on an actual installation, you will need to know the exact location and orientation of every element in the cell.

If the cell layout is simple, this information can be obtained through a coordinate grid or a ruler. For a more complex cell layout, you will probably need a technical drawing (e.g., AutoCAD) which shows the center point and orientation of all objects.

All measurements should be made with both the robot and the cell at the same point of origin and with the same orientation.

Screen layout is jumbled or crowded.

Peripheral axes do not move in

RoboCell.

Make sure all applications, including anti-virus monitors and network drivers, are closed. Then try installing the software again.

There may be a message box hidden behind the application window. Minimize the application windows to check for messages or prompts.

By default, the robot is placed at the cell's point of origin to simplify the teaching of positions.

The robot’s position can be changed only by means of its

Properties menu.

Use the SCORBASE View | Simulation & Teach or View |

Simulation & Run to reset the screen layout.

You can also use the SCORBASE Options | Load User Screen to reset a screen layout that you set and saved previously.

When SCORBASE is operating on-line, the peripheral settings defined in the CellSetup file are not loaded; the peripheral setup defined in SCORBASE is retained. Simulated peripheral axes that do not match the SCORBASE definitions will not respond to SCORBASE commands in the Graphic Display.
