So I want to build a robot powered by an arduino uno rev 3 for my science fair project. I want to compare tank control and joystick control. I will do this by building a race track and time how fast each type of control completes the race. My problem is that I don't know how to connect a controller to it. I have seen that I can control the robot with usb host by using a Bluetooth dongle to connect a PS3 controller to it. Also I've heard that you can control the robot over wifi. I'm a beginner in robotics and have little experience with coding. The science fair is in a month and I would appreciate it a lot if anyone could help.
This is the link to the video I saw:

I'm a product of the 60's and react accordingly...I have an entire portion of my brain filled with song lyrics from the 60's and 70's which causes me to not have room for important stuff like motors, pneumatics, electrical system and green lights... - RoboMom [more] 
Please help
