Hardware Architecture
In future We will be planning to use multiple SONAR and PIR
sensors attached to the sentry Roomba so that it can detect
more accurately and precisely in any direction.
For SONAR we will be using a 2 feet high platform/pillar
on which it can be mounted and placed on the top of the
Roomba so that it can measure the distance of a intruder
upto his trunk.The hardware design can be more robustly
designed by using material that can help SONAR and PIR to
get more focussed and free from extenal disturbances,
Software Architecture
In next Project we are going to implement the same concept
using a RTOS where we have implement funtionalities related
to timimg, CPU utilization, Multi threading, Scheduling
various periodic, Round Robin & system tasks wih managing
the Inter proces Communication.To get all these
functionalties we are going to use Logic Analyzer.
