The chassis

I wanted Takbot to be able to make 360° turns at a spot. This makes programming the movements simple and intuitive, apart from helping to maintain position and determine orientation using a simple wheel encoder. For this I chose a tank-type chassis, mainly cause it would run over things with great fury and awesomeness - if it should decide so. :)

After a lot of digging online, I decided to make my own using the Tamiya track and wheel kit from Superdroid robots. This is cheaper and apparently has more traction than the Tamiya's plastic track set . I used a couple of Tamiya's universal plate sets to make a chassis wide enough to accommodate my huge ATmega128 board (I made this one back when i didn't have the tools for SMD soldering).

Here's what it looks like:
