Android Controlled RC Car

Tags:
Category: Rolling
Progress: Completed
Cost: £20.00
Time to Build: 5 hours

Hi all.

This is a little project I threw together yesturday.
Taking a basic cheap as chips R/C toy car, I replaced the R/C circuit with a servo controller and bluetooth modem. I also changed the steering from a DC motor which gave 3 states; centered, full left and full right, to a 9g servo giving more precise control and a larger lock angles.

The app sends the steering angle and the speed value, calculated from the accelerometers, over a bluetooth SPP connection.

Thanks
Rob.

Cool!  Autonomous racing anyone?? :)  I'm working on an autonomous rc truck to navigate around a building in Boulder for a contest. http://robotbox.net/project/bot-thoughts/sparkfun-avc-road-bot  The prototype's Arduino-based for now. Will be switching over to an mbed soon.

That also reminds me, have you seen the neat little, android controlled, rolling balls that the guys at GearBox are working on? Could you build something like that?

I wrote the android App specifically for this project, but it was based on code I used in my Hexapod App.

Those balls appear to use an internal pendulum, in principle it wouldnt be too difficult to reproduce.
