It appears that maybe the animate.js file is in the wrong directory. Usually that file needs to reside in the same directory where the page is that uses the animate.js. Wherever that call for the animate.js is, I'm wondering if the animation is working or not. If there is a 404 error for the animate.js file, that usually means it is not where it should be and that the animation is not functioning.
The robots.txt requests are coming from spidering robots. Most will first check to see if you have a robots.txt, if not, a 404 page will be returned (page not found). You can eliminate those errors by building a robots.txt file and placing it in the root directory.
