This is the basic behavior of the system, where sound is the medium of communication. The Trigger is the element that initiates the chain reaction. It will translate the rolling motion into the sound that will trigger the modules laying in the ground. This event will start the chained reaction.
This is our initial Time Table and we've divided the overall project's development in two main blocks, the trigger element –stands for [T] in the timeline– and the module –stands for [M]–. Follow this link for a detailed description on each of the activities involved in our Time Table.
Bill of Materials
This Bill of Materials is thought for an initial prototype of one Trigger and two Modules. There's still a lot to figure out, but so far this is how it looks. You can follow this link for future references.
