Decided to build another tank with a smaller chassis and with motors that were geared lower. The primary control of this tank will be with the PS3 Game Controller.
This tank differs from the previous in that is has a much smaller foot print and is made entirely of metal (aluminum). Because of the smaller footprint it became more difficult to design. I had to go “up” to create space and this created a higher center of gravity then what I wanted.
One thing to consider before buying this tank: it is made from laser cut stock and comes with a blue peel film. The film removes easily but there are some very small metal fragments from the cutting process. These can easily find a way into a mouth or eye and in the case of an eye cause some serious damage. Here is a pic of what I am referring to (these pieces are very small a literally paper thin). Also some of the edges are sharp. This would not be a “best” choice for kids.
I will provide a quick build scenario and highlight some points of interest.
The build of this tank is fairly straight forward from a software perspective I refer you to PiBorg UK for the build instructions and you can of course refer to my other build for the Bluetooth and PS3 install. You will need to download the software from the PiBorg site in order to mate to their motor hat.
I must admit that while the crawler was a pain to work with because of its small foot print it is absolutely easy to control due to the lower gear ratio on the motors. Its not as fast as the first tank I build but has more power. The Piborg software is also quite robust. Here is a video:
