= ebuggy =
ebuggy is a controller for a little buggy made using Raspberry Pi and controlled by Erlang software.
== Communication ==
The communication pattern used inside ebuggy is as follows.
The motor process accepts commands (forward, backward,rotate) and when
it is done it will send a message motor_action_complete to the
requestor of that action.
The sharp process is responsible for detecting obstacles in front of
the buggy. All processes that are interested in knowing when there is
an obstacle in front of the buggy calls the sharp:alarm_obstacle/0
function.
When an obstacle is detected all processes will be sent the message
obstacle_present.
The "subscription" is a one-off, so processes have to call
sharp:alarm_obstacle/0 again if they still wants to be alerted.
