You can see the cardboard Truckbot in action here:

We started work on the Android Ardunio cellbot by looking at a kit from Oomlout called SERB. At $175 it was way out of our price range unfortunately. Oomlout provides everything you need to build your own kit but we wanted to use smaller servos ($3.50 each)  and needed a place to mount a phone. So we tried designing our own layout using CAD software called Solid Works. Then we made practice cuts using the laser on cardboard, which turned out to be sturdy enough to run without needing expensive acrylic.

Here is Tim explaining the truckbot in detail.

It was just by chance that the design started to resemble a truck, and future designs might make better use of the truck bed for payloads. The design should also work for acrylic and larger servos with some slight modifications. We were going to make mounting holes for the Arduino boards but found that plastic tie straps keep things simple and flexible.

You can find the CAD drawing for the truckbot, the Arduino source, and Python scripts on our Google Code project site. Check out pictures below from the 4-weeks that we worked on the robot at the Tech Shop in Menlo Park.

This video shows an early working prototype that accepts very simple commands via telnet from a PC. We’ve also tested connecting in via telnet from another Android phone and that works too.

You can get the Python and Arduino code for this on our Google Code project page. More pictures of the project are in this slide show and we’ll have additional instructions coming.
