Hello, MINDSTORMS Community! This is INT3RBOT! I named this robot INT3RBOT because it has 2 INTERchangeable tools! INT3RBOT actually stands for: INTERchangeable Bot Of Tools. (The other two tools won't fit on INT3RBOT, as I'll explain later...) As you can see, it looks quite like TRACK3R. This is basically TRACK3R in a highly upgraded form. Thanks to Karl4123 and lama-mantis for spending some time to give me some ideas for INT3RBOT. Sorry to those whose ideas were not carried out; I'm either unable to do it or it may be present on INT3RBOT II. For detailed info, please read additional information.
