Code

Hattori Meowzo - Web App for Robot Cat Toy

Download the code, open in Visual Studio and then build and publish for 'linux-arm'. For the code to run as is, move the publish folder to the desktop on the Raspberry Pi. Rename the folder to CatToyWebApp. For object recognition to work, you'll need to have compiled the source code for OpenCvSharp and then copy & pasted the 'libOpenCvSharpExtern.so' file into the root of the CatToyWebApp. I would reccommend double checking the paths listed in the top of the Camera class to ensure it lines up with where you've placed the project on your Raspberry Pi.
