 Improving security services offered by human patrols inside buildings.  Remove the need of human presence to perform rounds within a dangerous environment.  Reduce the number of security personnel required within an area

 Continuous patrolling along a set path within the building.  Video surveillance of area being patrolled  Event alerts: intruder or fire.  Operator control of the robot

 Wireless communication between an operator and the robot  Wireless live-stream video of the robot surroundings  Manual robot navigation  Autonomous navigation along a pre-defined path  Human, fire and obstacle detection

 Establishes and maintains communication with the robot.  Captures, displays and stores images and other sensor outputs  Alerts the operator if anything anomalous is detected by the sensors.  Accepts keyboard inputs from the operator and sends them as commands to the robot.

 Can automatically detect and support a wide range of image acquisition devices.  Acquire images and video from cameras and frame grabbers.  Built in Matlab.

 Displays video, snapshots and all information transmitted by the server.  Alerts operator if something anomalous is detected(Heat and obstacles).  Allows the operator to control the robot manually.  Built in Matlab

 Center of the client system.  Communicates with all other modules.  Processes and storing images from Image acquisition module  Updates the GUI every 0.1 of a second  Exchanging information with Communication module via API  Built in Matlab

 Establishes and maintains communication with the Server.  Sends and receives messages concurrently.  Delivers messages from the Server to the processing unit, and vice versa, via an API.  Built in Java.

 Capable of following a line in a straight path as well as curves  Mark detection  State machine based algorithm  Utilizing interrupts to detect state transitions  Can handle recovery from minor line interruptions

 Sonar and Thermal Array polled periodically to acquire data.  Distance to an object indicated by sonar determines obstacle presence ◦ Obstacle present if distance < 25cm  Temperatures registered by thermal array are analyzed for human presence and fire ◦ Human temperature range: 36 °C - 40 °C ◦ Possibility of a fire: Ambient > 45°C or Spot Temperature > 90 °C

 Control the movement of the robot remotely  Server receives commands from the client and forwards them to the peripheral Arduino which controls the wheel servo motors

 Server run on the Main Arduino  Establishes wireless communication with client making use of the Hydrogen Shield.  Interprets received commands from Client and transmits appropriate alert messages to Client.  Minimal number of messages sent to avoid network clogging and high maintain transmission speeds.

 Each component from the client side and server side was tested individually  Overall system testing ◦ Establish connection. ◦ Manual control of the robot using GUI. ◦ Switching between autonomous and manual control. ◦ Sending and receiving messages from the server and displaying alerts. ◦ Live video streaming ◦ Fulfills surveillance requirement.

 The current solution is reliable for its use in surveillance for the following reasons ◦ Camera transmission is independent of a network. ◦ Provides both autonomous and manual navigation. ◦ Client acquires, and stores images independent of a network. ◦ Additional microcontroller  However, Communication between robot and human operator is as reliable as the network over which it takes place

 First term achievements: ◦ Control of wheel movement ◦ Sonar operation and obstacle detection ◦ Wireless communication establishment ◦ Server Implementation ◦ Graphical User Interface  Second term achievements: ◦ Line following functionality and mark detection ◦ Video streaming ◦ Redesign of GUI to suit new application ◦ Thermal array operation and human/ fire detection ◦ Integration of system

 One of original main requirement: Human detection based on image processing.  Replaced by Thermal sensor.  Two microcontrollers instead of one.  Smoke detector will not be included.

 Tasks distributed equally amongst both team members. Both members participated during the integration and testing phases.  Constant cooperation and communication of ideas between members, especially during testing and debugging periods.

 Overall cost of system: $800 (in components)  Targeting corporations and organizations looking to improve an already existing security system. ◦ Museums, art galleries, retirement homes, hospitals, storage facilities etc.  Robotic system can perform continuous patrolling and oversee a larger area. Provide event alerts.  Easy to operate  Financially feasible solution
