When I say "Left drive" I'm referring to the drive mechanism which turns it left -- which happens to be the right hand sprinkler. It steers like a bulldozer.
It's not really an app I'm using - the control box runs an A5-V11 Linux Mini Computer (smaller than a bic!) and it has a wifi hotspot built in, with a webserver. So I'm just using a web browser on the phone to access a CGI on the webserver which passes commands to the navigation engine.Report Video
