Welcome to the Adept iSight TutorialThis tutorial will walk you through the creation of a basic, functional machine vision application. The tutorial assumes you are familiar with Adept DeskTop and with the operation of the Cobra i-Series robot.Tutorial Overview•Install the hardware•Install the software•Create a vision application•Add a MicroV+ program•Test the integrated applicationSystem Requirements•PC running Windows 2000 SP4 or Windows XP •PC with an OHCI-compliant 1394 (FireWire) Bus Controller•Windows .NET Framework. If it is not present on your computer, it will be installed during the software installation.Note:The type of PC processor will influence the execution speed of the vision applications.Before Starting the TutorialYou will need a typical object/part for the tutorial. Use a part that: •the robot can easily grip, or point to, with the robot end effector, and•that is suitable for vision applications.Adept iSight Tutorial
Module 2: Install iSight HardwareInstall iSight HardwareInstall the RobotRefer to installation instructions in the manuals that came with the robot:•Adept Cobra i600/i800 Robot User’s Guide (P/N 03589-000)•Adept Cobra i600/i800 Robot Quick Start Guide (P/N 03589-000)Install the Lens1.Locate the lens that came with the package.2.Install the lens on the camera. Do not over-tighten.3.Do not set the lock screws, since you will need to adjust the lens aperture and focus later. Install the Camera1.Locate the IEEE 1394 (FireWire) cable that is included in the shipment box.2.Connect one end of the cable to the 1394 port on the Basler camera. See image.3.Mount the camera in the workcell using the camera mount brackets. 4.Connect the other end of the cable to a 1394 FireWire port on the PC. A hub may be required if the PC (laptop) has a 4-pin port.5.Typically, you should mount the camera so that it is perpendicular to the workspace.6.Make sure that the installed camera clears the top of the robot. Note:In Windows 2000 you may get a "Found New Hardware” popup. In such a case, click Cancel: the Basler camera driver will be installed with the iSight software.Next:Install the SoftwareAdept iSight TutorialOverview of Adept iSight SetupBasler Camera connection portsBack of Baslercamera IEEE 1394 port 2
Module 3: Install the SoftwareInstall the SoftwareThe software installation process will install the following:•Adept DeskTop 3.1•Adept iSight 1.0•Basler BCAM camera drivers•Sentinel Super Pro driver for the USB hardware key (dongle)Before Installing•If Adept DeskTop version 2.3 or previous, is installed on your computer, you must uninstall it before installing the new version.•If Adept DeskTop 3.0 is currently installed on your system, you do not have to uninstall it before installing the new version.•Install the USB hardware key (dongle) that came with iSight. This dongle is required and must be present at all times to ensure the proper functioning of iSight.Installing the Software1.Install Adept DeskTop from the Adept DeskTop CD-ROM. 2.Follow the instructions on screen. 3.Do not change the default destination folder to which Adept DeskTop will be installed.4.Install iSight from the Adept iSight installation CD-ROM.5.Follow the instructions on screen.6.Do not change the default destination folder to which iSight will be installed. The installation automatically install iSight in the same destination as Adept DeskTop.The installation is now complete. The drivers for the Basler camera and the Sentinel hardware key are installed during the iSight software installation. You do not need to reboot your computer before starting Adept DeskTop.Next:Open the Vision Manager Adept iSight Tutorial3
Module 4: Open the Vision ManagerOpen the Vision ManagerVision applications are created and managed in the Vision Manager window in Adept DeskTop. Open Adept DeskTop 1.Open Adept DeskTop. 2.Connect and power up the robot. For additional instructions refer to the Adept Cobra i600/i800 Robot Quick Start Guide. Open the Vision Manager1.From the Adept DeskTop menu, select Tools >Vision.2.The Vision Manager opens, similar to the image below.The Vision Manager WindowSequence Manager:From the Sequence Manager, you manage and edit the sequences that make upyour vision guidance applicationCamera ListFrom the Camera List, you can configure camera parameters and launch the calibrationsYou can dock the Vision Manager anywhere in the Adept DeskTop window•Before creating a new vision application, you will have to adjust the camera and calibrate the system. •Warning symbols such as those in the image above indicate that the system has not been calibrated.Next:Adjust the CameraAdept iSight Tutorial4
Module 5: Adjust the CameraAdjust the CameraTo adjust the camera lens you must open a live display.Open Live Camera display1.In the Available Cameras list, select the Basler Camera (A601F…).2.Click the Live Display icon. See image.3.The Live Display opens.4.Important: Make sure that the entire area covered by the camera field of view is within the robot’s work range. Otherwise, reposition the camera.Adjust Lens Focus and Aperture1.Open the Live Display window to guide you in adjusting the lens aperture and focus.2.Place one or more objects in the field of view.3.Use the display’s zoom options by right-clicking in the window. See image.4.Adjust the focus until objects in the display are sharp.5.Once you have obtained the best possible focus, adjust the lens aperture (f-stop) until you obtain a well-contrasted image. If it is too highly contrasted (saturated) you will lose detail.You can now optionally adjust camera parameters, although the default camera parameters should be satisfactory for this tutorial.Next:Adjust Camera Properties (optional)Adept iSight TutorialOpening a Live Display WindowLive Display Window with Zoom OptionsOpens the Live Display window 5
