as far as wifi is concerned it's been hit and miss from what i've read on the forum. wifi to control the motors with the EZ-b you are going to need two h bridges i would suggest reading through the forums and the tutorial section to get aquainted with ez-b and ARC before you make a purchase. if you buy the kit you get a nice camera, servos and ping sensor ect.. you can be successfull in building a robot mower with the EZ=B. this controller is the best one out there in terms of ease of use, everything is simple to setup and modify for any project. good luck, and welcome to the forum!
