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.
