Design and fabrication of fire fighting stairs climbing robot

Project Title

Design and fabrication of fire fighting stairs climbing robot

Project Area of Specialization RoboticsProject Summary

For disaster mitigation as well as for urban

search and rescue missions, it is often necessary to place

sensors or cameras into dangerous or inaccessible areas to get

better situation awareness for the rescue personnel, before they

enter a possibly dangerous area. Robots are predestined to this

task, but the requirements for such mobile systems are

demanding. They should be quick and agile and, at the same

time, be able to deal with rough terrain and even to climb

stairs. This  presents the design and implementation of a

feedback control system for an RF remote-controlled stair?climbing robot. The robot is controlled using PIC

16F877A.The paper presents a complete integrated control

architecture and communication strategy for a system of

reconfigurable robots that can climb stairs. Its mechanical

design is suitable with back wheel to drive the robot over

rubble, and large wheels in the front driven by dc motor for

climbing stairs. The operator can monitor the robot operation

by using video that are captured through a camera on the

surface of the robot. The robot system is implemented by using

MikroC and visual basic programs. Experimental trials

showed that the implementation of the behavior control

systems was successful. 

Project Objectives

1: Design and develop fire fighting robot.

2: Design and fabrication of stair climbing robot.

3: Extinguishe the fire system. 

Project Implementation Method

First, the robot is controlled by using remote,

the serial remote contain pushbuttons and

potentiometer. This Pushbuttons control movement

of motors (DC motor and stepper motor) and

potentiometers control PWM.

Second, the robot is controlled by interfacing stair?climbing robot with PC; in this way serial port was

used. This port consists of two wires to transfer

data (one for each direction) and a number of

signal wires.

Finally, RF module or remote is used to control the robot

wireless. High MHz RF Transmitter and

Receiver is wireless data transmit and receive

module with VHF/UHF super high frequency. It

has strong anti-static protection and high reliabilit

Benefits of the Project

Lightweight and rugged design for increased portability.

Platform can be outfitted with an array of sensor capabilities.

More portable than the Packbot

Used in different industries as fire fighting robot 

Technical Details of Final Deliverable

structure of the stair-climbing robot which consists of:

Power sources, charger circuit, motors (DC motor, Servo

motor), and wireless and wire modules. The

brain of the robot is PIC16F877A

Primary source of power for the robot are lithium

batteries (Li-ion) because of its characteristics and

advantages. Two batteries (12 Volt 9 Ampere) deliverers,

respectively, to provide 24 volts and Can recharge this

batteries using charger circuit
