Camera, followed by problem - prevents the target centered

Hi, I'm working on a project as part of my studies building and programming a machine gun. I have a prototype built and tested with R/C and I have no problem tracking stuff when the unit is static (mounted on the chassis or next to the platform).

What I want to do, is to be able to fix the camera to the "barrel", so it moves with him. In this way I avoid having to map and re - map servos according to distance, angles, etc. As long as the target is in the center of the image of the acquis, I can assume that the goal is correct.

What I do now is divide the image into 3 'zones', left, Center and right and pan a camera attached to a servo regarding the whereabouts of the target. This is the question that I have - when the reached target the center of the picture, the camera continues to run until the target is the opposite, toggle direction and repeat the process. I'd appreciate it if someone could tell me what I'm doing wrong or missing, and if there is another way to do it.

I use the Arduino module and an arduino nano for servo control.

* When the unit is supposed to stop, as an input to the servo I got a reading of its current position, so it just stops.

Due to the "never compare SGL, DBL EXP 0 /! 0, if force you the number to the nearest whole number of you AND that you are not working with complex numbers you should be OK.

Please find attached my update to your VI (removed mathscript node) and the added shift registers - noticed while doing what you do not know the initial starting of the Pan and Tilt position - this will be affected by the range of your servos and is something you should consider that you could get on the edge of your rotation and try to drive the camera too far.

Hope this helps

  • HP Deskjet 1512: Error applying driver settings, then a problem prevented the scanned Document

    I can't find any question about scanning on this product, I want to post a picture of my screen, but can't. This occurs when you try to scan anything. The first screen comes up with "Error applying settings to Driver" then then once the product has tried to sweep is the error message "a problem prevented the Document are analyzed. I had this product since almost a year and were only able to analyse once. I tried in vain to follow all the troubleshooting steps and nothing works. I'm starting to hate this printer. I uninstalled and reinstalled, restarted my computer and more after each uninstall and reinstall. I unplugged USB and power cords. This software/scanner driver sucks!

    I do not usually bother with these sites, but since I seem to be the only person who knows the solution for application error settings driver with scanners I should share it. I went through three Microsoft technicians and they were at a loss. They usually end by saying that I have installed a bad iso image and need to download a new one and reinstall. But anywho the fix is... run your registry editor and go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StillImage and remove the key from the photo don't worry it will be recreated with the key parameters appropriate because the pilot he rewrites and there you go no scanner error more I have to add that I am on win 10 x 64 with a Canon mp280 printer , but this should apply to windows 7 and upwards.

    1. what web browser do you use?

    2. when the problem started?

    The website you are visiting had a server problem preventing the display of the Web page. It often occurs due to maintenance of the site, or due to a programming error on interactive websites that use scripts.

    For more information, see the following article:

    Get help with the Web site (HTTP error) error messages.

    If you use Internet Explorer, you can read the following article and try steps 2, 3 and 4 to solve the problem.

    Internet Explorer is slow? 5 things to try

    Note: Resetting the Internet Explorer settings is not reversible. After a reset, all previous settings are lost and cannot be recovered.

    You can also visit the following links to support Windows Live:

  • XP hangs at startup and the dialog box provides the following: a problem has prevented Windows to check exactly the State of this computer

    I am rebuilding a system that has been attacked by several viruses and had to rebuild XP using the Windows installation disc.  After completing the repair, I was greeted by the XP logon screen and I tried to log in as administrator. The standard screen grass-hill appears followed by a Windows dialog box to activate product indicating "a problem has prevented windows to check exactly the State of this computer.  To keep your copy of windows must be activated with Microsoft. You want to activate Windows now? "If I choose 'No', then Windows drives me back to the login screen.  If I choose "Yes" then Windows does nothing - activation does not occur and XP does not start... the system just hangs.   I also tried to open a session without failure, but he said that I could not activate safe mode and started back me to the login screen.  I am able to get to a command prompt, if I select Mode safe mode with prompt at startup.  FYI, I am able to view the structure of this version XP Directory when I configure the HARD disk as a slave on another system drive.  Any help to resolve this matter will be highly appreciated.

    I have exactly the same problem and after 2 days of searching and trying stuff found on the internet, I have solved this problem.

    At my computer configuration: Windows XP sp3 with IExplorer 8, but had to go back to the repair facility after that some system files have been corrupted, do not know why.
    My repair CD installation was: Windows XP sp2

    In my view, the main problem is that after the installation of repair, the system obtained in conflict of existing versions of IExplorer 7 and 8. IE 7 & 8A prevented the application of activation of MS (OOBE) of working after the installation of repair, the OOBE application silently chrashed and prevented the logon process.

    I couldn't connect even in safe mode, BUT with failure + command prompt, safe mode I managed to log on! So, choose the mode without failure + command promt in the trunk. Then open a session with success. Then close the command prompt and press CTRL + ALT + DEL to Task Manager. In task manager launches the new application "c:" and answer 'No' to the following question, and after an error message you c: drive open and you'll have office. You can close the System Restore Wizard who opened. Then go to c:\windows\ie7\spuninst and run spuninst.exe. Do the same to c:\windows\ie8\spuninst. After you have uninstalled both, restart windows, and after the first issue of activation, you should get the big activation dialog box.

    I have spent a lot more time, because I was told that uninstall IE7 and IE8 is possible to do this via the command prompt. I did, but it has not fixed my problem. Then I tried a thousand other tricks at the same time.

    Please let us now if this helped you.
