Video of complete robot driving:
1-Rc Car (new or used, choose one that could easily have a Rc servo fitted in the steering system. We got ours from Radio Shack.)
1-Barracuda wifi robot controller (http://www.robotics-redefined.com, use coupon "instructables" to get 10% off) http://www.robotics-redefined.com/index.php?main_page=product_info&cPath=28_30&products_id=62&zenid=c4fd241aa334c50cf189918d38319430
1-Wifi Router ( brand does not matter, we will be using a Linksys)
1-Network Camera (again, any brand will work, we will be using a Linksys)
1-5v Regulator for camera (may be different if using a different camera.
2-3 7.2v Rc Batteries (3300mAh or greater recommended)
Misc wire, solder, tape etc.
***NOTE***: As of this writing after testing the wifi robot / spybot, I would encourage the use of a different Network Camera. The Linksys camera worked ok but not great, I have heard good results with the Panasonic line of cameras.
Step 1: Step 1: Hacking The Car
The two red batteries are to power the main motor and the barracuda wifi controller. While the blue 7.2v battery will power the Linksys router, 5v Regulator for the camera, and the steering servo. Three batteries are not needed, but i just find that it makes the wifi robot / spybot more reliable and allows longer run times. If you opt for two batteries the Linksys router can handle 40v, so you will be fine running it straight off of the two packs. The same with the 5v regulator. Te only problem will be the power for the steering servo, so you will either have to add another 5v regulator and run it off of that or just get a higher amperage 5v Regulator and run the servo and the camera off of it. The latter would be easiest.
