bigbro upgrade

This time I added the Solarbotics L298 Compact Driver Kit, the car is now much more powerfull and it is very cool to drive.

In the photo you can see a proto shield where I connected the Xbee, the motor and servo and the LEDS, than the L298N board and a 6v voltage regulator.

I added a small video with some “stunts”  :)

(I´m using the G-Remote to drive this beast!)  :D

I love the way it looks in the night

While playing with the digital camera I have found that it performs nice light trails:

After completing the new motor driver board, now I feel ready to continue with the development of this bot..

For now it´s just remote controlled, but it will have some intelligence soon.
I will try to add microphones and use them as sound sensors. If I add for example 4 microphones, one on each side of the bot I could detect where does the sound come from and make it move in that direction, then add a couple of distance sensors to avoid obstacles..

My living room seems to be too small to drive this bot..

see it on MAKE :]

Here goes my second robot. This turns out to be the 4th robot actually  :)

I found this offroad car in an old junk and it was love at first sight!

Now I want to add some brains and sensors and give him a new life :]

The steering DCmotor burned out and I’ve removed all the gears and stuff around it. I’ve made a hole and installed a servo motor to do the steering, it seems to work out good!  I can´t post a video because the motor shield I was using burned out as well, now I’m working on a custom motor driver  …  (it seems I’m having lots of burning issues lately)  :D

My custom motor controller seems to work quite well!  These videos show the servo steering.
