Here's how I modified a cheap RC car so that it can be controlled from anywhere in the world. The whole project took about 4 weekends to implement, working around 6 hours per weekend. The whole idea was to build an RC car that could really be *remotely* controlled, I'm talking thousands of kilometers of range... As a bonus, this device acts as a tele-presence bot since it uses a netbook with skype to provide video feed to the person who is controlling it. Let's have a look at how it was built.
I went to Toys'r'Us, and found this little baby:
I stripped it of the unnecessary bling. I then had to wait for my Arduino to arrive... It finally came.
I started working on what was my first Arduino project.
I got my computer to talk to the Arduino. I then built the little circuit of switches using opto-isolators, and connected it to the remote control of the RC car.
I used a bunch of self adhesive tie mounts, and many tie-wraps to firmly hold the PCBs in place.
Here's the final assembly:
A couple more tie-wraps, some hockey tape, and voilà! Here's the final result:
You can find the source code of the project at:
I might explain the circuit in more details in the coming days...
Thanks for passing by,

I saw your video showcased on Engadget last Friday. Cool stuff! Very similar to what I've been working on for the past few weeks. My implementation costs half the price though ;-) We should race them some day :-)
