TRTL should be built upon existing open | TRTL should be built upon existing open hardware/software stacks. ones with active/lrage communities attached to them. This will make the transition from TRTL to general hacking a simple process. It also adds value to the kit - the purchaser not only gets a TRTL bot and its inherant educational process, but also an 'AVR clone' - the entry point into the land of arduino. | ||

Arduino is an easy to use | Arduino is an easy to use prototyping language developed for ATMega32 based microcontrollers. There is massive community support for all things arduino. This choice is in line with the project aims to build on existing community supported platforms. | ||
The use of bitlash is up for debate since i cant think of one good reason it should be used over an arduino sketch, but i like the idea of creating custom functions and executing them for movement et al. | The use of bitlash is up for debate since i cant think of one good reason it should be used over an arduino sketch, but i like the idea of creating custom functions and executing them for movement et al. | ||
