Porsche controlled by MSP430, First Standalone Drive Tests!!

Posted by admin on August 9, 2011

As the title says, the first drive tests!!, but also a:

DISCLAIMER: The video is pretty dark since it was recorded using my mobile (play it fullscreen for a bit more clarity).

And the robot is pretty stupid, or at least near sighted, since the IR sensor is detecting the obstacles, but pretty late (it slams into them first ;) )  But that was expected.

It will be optimized eventually (read full post), and also the actual sensing code, and general use of delays will be recalibrated and optimized a bit more. Here are the very first drive tests, as mentioned, recorded on a mobile phone:

 

Eventually the standalone code will be improved a lot. Using steering, more sensors, and more logic.

Also want to change the IR sensors function to first sense the general light level before the IR led, then activating it, sensing again, and calculating the difference. That should improve obstacle collision detection a lot, and lower the number of errors in more diverse light level situations. But i don't know how many pins i will have left so that might limit the number of sensors. Checking out configurations atm.

For my next project, i have received an Ultrasonic Rangefinder and servo, so then will at least be easy to get an accurate measurement, once working..

But since it does drive standalone, with PWM enabled while keeping the serial code in place, and somewhat functional IR sensing, i thought i'd share it anyway

And  I did not add the code since it is currently a copy pasted mess from all my individual module tests, but if someone really want's it, i'll try to clean it up a bit and post it somewhere

Cheers!
