Introduction to robotics oussama khatib pdf files. If you are using Selenium web driver with Python,you can use PyVirtualDisplay, a Python wrapper for Xvfb and Xephyr. PyVirtualDisplay needs Xvfb as a dependency.

On Ubuntu, first install Xvfb: sudo apt-get install xvfb then install PyVirtualDisplay from Pypi: pip install pyvirtualdisplay Sample Selenium script in Python in a headless mode with PyVirtualDisplay: #!/usr/bin/env python from pyvirtualdisplay import Display from selenium import webdriver display = Display(visible=0, size=(800, 600)) display.start() # now Firefox will run in a virtual display. # you will not see the browser. Browser = webdriver.Firefox() browser.get('print browser.title browser.quit() display.stop() EDIT The initial answer was posted in 2014 and now we are at the cusp of 2018.Like everything else, browsers have also advanced. Chrome has a completely headless version now which eliminates the need to use any third party libraries to hide the UI window. Sample code is as follows: from selenium import webdriver from selenium.webdriver.chrome.options import Options CHROME_PATH = '/usr/bin/google-chrome' CHROMEDRIVER_PATH = '/usr/bin/chromedriver' WINDOW_SIZE = '1920,1080' chrome_options = Options() chrome_options.add_argument('--headless') chrome_options.add_argument('--window-size=%s'% WINDOW_SIZE) chrome_options.binary_location = CHROME_PATH driver = webdriver.Chrome(executable_path=CHROMEDRIVER_PATH, chrome_options=chrome_options ) driver.get('driver.get_screenshot_as_file('capture.png') driver.close().

Dos proyectiles se lanzan verticalmente hacia arriba con dos segundos de intervalo; el 1° con una velocidad inicial de 50 m/s y el 2° con una velocidad inicial de 80 m/s calcular A) tiempo que pasa hasta que los dos se encuentren a la misma altura.

I suggest using Phantom Js for more info you need to visit As far as i know PhantomJS work only with Firefox. After downloading PhantomJs.exe you need to import to your project as you can see in the picture below Phantomjs is inside common>> Library>> phantomjs.exe Now all You have to inside your Selenium code is to change the line browser = webdriver.Firefox() To something like import os path2phantom = os.getcwd() + ' common Library phantomjs.exe' browser = webdriver.PhantomJS(path2phantom) The path to phantomjs may be different. Change as you like:) That's it, it worked for me. And definitely he will work for you to, Cheers.
