This are slides of a project am currently undertaking.

3.  SAFER is basically a robot designed to detect,
find and extinguish a fire in a normal house
environment.
 It employs GSM technology to notify the resident
of house of the fire.
 It uses Infra red sensors to navigate around the
floor plan, flame detection sensors to detect and
pin point the fire and carbon dioxide gas to put
out the fire.

4.  The need for a device that can detect and extinguish
a fire on its own is long past due. Many house fires
originate when someone is either sleeping or not at
home. With the invention of such a device, people
and property can be saved at a much higher rate with
relatively minimal damage caused by the fire.
 Our task as Electronic and Computer Engineers is to
design and build a prototype system that could
precisely detect a fire, notify the person in charge via
GSM (SMS) and activate the robot to initiate the fire
extinguishing process.

5. MAIN OBJECTIVE
To design and build a semi autonomous fire
extinguishing robot (SAFER)

6.  To employ microntrollers to integrate and
develop controls for the prototype system.
 To use GSM technology (SMS command) to notify
the person in charge via a preset ID at the same
time starting the robot.
 To use the robot to detect and extinguish a fire in
a pre-designed environment.

7.  SAFER seeks to provide a way in which fires can be
extinguished in the shortest time possible and also
sending a signal from a GSM module to inform the
owner of the house of a fire breakout.
 SAFER eliminates delays and overdependence on
the fire department which is very prone in a
developing country like Kenya.
 This project is also in line with Vision 2030 which
seeks to intensify innovation in priority sectors
particularly in the industries which are a key player
in Kenya achieving a mid level economy by 2030.

9. The project is divided into the following sections:
 Communication
 Navigation & Power supply
 Control

11. Rechargeable (Ni-MH) batteries to supply
power to the motors as well as run the
microcontroller and sensors.
The reasons for this selection are:
 Durability
 Capacity
 Weight

12. The motors to be used are the brushed DC
motors. The reasons behind this are:
 Low initial cost
 High reliability
 Simple control of motor speed
 Cheap drive design
 Easy torque control

15.  Embedded microprocessors are used for all
industrial robots
 They perform the required function and also enable
interfacing of the various kinds of sensors, tooling
devices e.t.c.

16. We intend to use the Arduino Duemilanove. The
choice was based on the following reasons:
 Inexpensive
 Cross platform
 Simple and clear programming language
 USB connection
 flexible

19.  Fire Alarm is detected by the tone decoder LM
567
 Wall proximity sensors: sharp GP2D12
 White line sensor: QRB 1114
 Flame detection sensor: Hamamatsu UV Tron
