To controll the robot I designed a program that gets the subscriber amount from my chanel URL and then sends it every second to the COM-port that is connected to the arduino. The arduino than reads the received string and reactions accordingly to it. I used a 30A brushed ESC as power supply to get the 5 VDC for the servo's. I uploaded all the stl-files but the body stl-file was to big to upload here so you can find this stl-file (and the others also) in my dropbox link.
