The Wi-Fi enabled RC Car
This is a short summary about my Wi-Fi enabled RC car.
The car was a 1:6 model of a SUV which I bought from eBay for about
40Euros(currently about 60US$). Strapped to this is a 266MHz dsl router
running OpenWRT 0.9. Attached to this device is a USB web cam and
some homebrew electronics to control the cam, the steering and the
motor.
The car can be fully operated from a single remote computer which is
also Wi-Fi enabled. Control commands are passed through a OpenVPN
tunnel
and video is streamed to the remote computer via a simple protocol.
The router is an Asus WL500GP which features two USB 2.0 ports on
which the web cam is attached. The web cam is supported by the spca5xx-le driver and
streaming is done by a program called servfox.
The care is controlled by a joy pad attached to the remote computer.
Also the web cam can be tilted and panned via the game pad.
I will post some more information
on this project after my exams in march.
Here are some impressions:
