Our current electronics setup is run using a Real Time Operating System from UVic running on an ATMEGA 1280. Drivers have been written - the system works - but is rather heavily taxed by the number of things which it must do. We would like to do path planning, more sensor processing and more intelligent decision making. To that end we've been discussing the use of a more powerful processor to add the higher level of control which is the next step in our development. We chose the well maintained Arduino platform for it's ease of use, its flexibility, the soundness of hardware and most importantly the community which surrounds it. The Raspberry Pi is now a hit in the hobbyist community which sports a powerful ARM processor, a bunch of IO, several projects which integrate it with our current processor and a low cost. So as mentioned in the previous post we've purchased a couple to try them out.
