Similarly to the “Orangutan” robot, FREEbot was meant to encourage customers to buy specific robotic components from online shop I was working for. It is based on very popular FREEDOM-KL25Z, which could be event received for free at some point. Freescale’s innovation was Code Warrior with Processor Expert tool, which allows user to configure most of the peripherals with beginners-friendly clickable forms.
FREEbot consists of cheap parts, including Pololu KTIR transoptors, Pololu step-down regulator and Arduino motor shield (L298 + Schottky diodes). Sales of those parts skyrocketed a week after publication of my “Step by step guide – how to build FREEbot”, which you can find here.
