I’m in the process of putting together a list of hardware to purchase for my project. Until the Raspberry Pi is released (which should be a couple weeks from now), the most important piece of hardware I’ll be acquiring is likely the mobile platform of the rover – i.e. wheels and motors.
Right now it’s between Dagu’s Mr. Basic for around $30:
Or Dagu’s Rover 5 for around $65:
While I’m pretty confident Rover 5 is the better one of the two, this will likely come down to price. And my policy at this stage in the project is “as cheap as possible”.
