In paralell with Pingubot developement race, was the arduino based bot. I liked better this one, since the Pingubot, except for the programming, had almost everything in its place mainly due to the integrated sensor bar and driver for motors.

Arduino has been a great platform for robotics and micro bots. Since it's open source, a lot of clones / mods based on it have flourished over the last 5 years. Main advantage is that code can be or mostly fully reused and Arduino's greatest asset is it's comunity and the great amount of shared work and code you can find on the Internet.
One of these is pinguino. While arduino is AVR microcontrolled based, pinguino is PIC based.

In November I attended another course, this time based around a well known platform: PICAXE.

We worked with picaxe 28x1 project board. It was great fun and learning, because we had all the components, cut, printed, acid washed, drilled and soldered everything to get the board working. Flowchart programming was good for a start but it immediately becomes a mess if the program becomes just a bit long. It’s great for kids to start programming though.

In spring of 2010, I attended a microbot workshop where we were supposed to learn to build and program a simple line follower, with two sensors and two servos. 3003 Futaba servos where mechanically freed from tops and potentiometer was detached from axis and left untouched (after being calibrated), so a pwm signal from the PIC microcontroller would mean continuous rotation movement in the servo.
