Our OFFLINE competition is going on. I rebuilt my robot LegoMinibot and decreased his weight in a half, made a new motor-gears from the $3 toy-car, $0,5 motor and IR-sensors from an old computer mouse used as wheel encoders.
The speed of this robot increased twice as much.
My previous result was 27 seconds and now it's only 14 seconds! Not bad but pretty far from our current champion
We have also a new competitor who built his robot based on the toy tank chassis and the same robot board as my robot (it's a Minibot robot board powered by AVR Atmega MCU). This newcomer showed the result 17 seconds as at once!
Now I'm working on PID control algorithm to break the record - our champion (very experienced designer of robots) helps us by his useful advice. Not only me who eager to beat his record by PID-algorithm but the second champion is forking out too, so I have to work hard
It's really amazing!
