OBJECTIVES The main objective of this project to build a cost effective

and efficient wireless robotic system for industrial application with wireless live video streaming.

To provide a platform for Many industrial applications that require inspections and surveillance in hard-to-reach and hazardous areas , thus acting as a substitute for human in hazardous environment.

The other important objectives that are associated in installing of robotic systems in industries are;

1) Saving of manpower.

2) Improved quality & efficiency.

3) Ability to work in any hostile environment.

To detect unexpected dangerous events like fire accident,

GAS leakage, High temperature etc…

ABSTRACTIn any industry, a large fraction of the work is repetitive and judicious application of automation will most certainly result in optimum utilization of machine and manpower. Here our ROBOT plays a vital dual role. . They are mainly used to perform ‘pick and place’ actions and also this Intelligence robot is developed to detect dangerous Gas/Smoke, fire, temp., humidity by using some sensors interfaced to an 32 bit microcontroller.

In our project the robot is designed to work automatically as per the command given by the program... Ex. If particular Smoke is detected, robot will switch ON the Alarm Unit and send an alert message.

The Robot will send the real time video streaming , which could be seen at remote monitor and control action can be taken accordingly to control the robot are using high range ZIGBEE remote control.

EXISTING SYSTEMS

Designed and developed an intelligence robot to detect dangerous Gas/Smoke by using an 8 bit microcontroller.

To move in all the direction like forward, reverse, right and left as per the command given by the controller.

Communication between robot and PC is bidirectional communication, which takes place by RF modem with 9600 bps.

If any gas/smoke detected, robot will switch ON the Alarm Unit.

The video and audio are monitored at the remote PC.

For transmitting video, RF camera has been used.

PROPOSED SYSTEM

This system is made more useful by migrating from 8bit to 32-bit ARM 7 microcontroller.

We are using some additional sensors like temperature sensor, humidity sensor and fire detector along with the GAS/Smoke detector.

We are using SONAR to avoid collision with obstacle

This robot has a Mechanical arm using for PICK and PLACE objects.

The high range ZIGBEE transceivers are used.

A GSM modem is used send alert SMS.

SOFTWARE DETAILS

Keil IDE The Keil MDK-ARM Microcontroller Kit is a

complete software development environment for the wide range of ARM, Cortex-M, and Cortex-R based microcontroller devices.

Flash magic Flash magic is a PC tool for programming flash

based microcontrollers from NXP using a serial or Ethernet protocol while in the target hardware.

IMPLEMENTATION

A RF camera is used to give a live video stream to a remote user.

A ZIGBEE transceiver is used for wireless communication.

A mechanical ARM is used to pick and place objects.

A temperature sensor is used to measure the temperature in that region.

A smoke and fire sensor is used to detect any gas leakage or fire accidents by alerting.

A Humidity sensor is used to check the humidity of the industrial environment

Switch board interfaced with 8051 Micro contoller is used to control robot movements.

INTERFACING GSM TO LPC2148

GSM modem interfacing with microcontroller for SMS control of industrial equipment. The sending SMS through GSM modem when interfaced with microcontroller or PC is much simpler as compared with sending SMS

Ultrasonic Ranging Module HC - SR04

Ultrasonic ranging module HC - SR04 provides 2cm - 400cm non-contact measurement function, the ranging accuracy can reach to 3mm. The modules includes ultrasonic transmitters, receiver and control circuit. The basic principle of work:

(1) Using IO trigger for at least 10us high level signal,

(2) The Module automatically sends eight 40 kHz and detect whether there is a pulse signal back.

(3) IF the signal back, through high level , time of high output IO duration is the time from sending ultrasonic to returning. Test distance = (high level time×velocity of sound (340M/S) / 2,

Fig 5 : SONAR

(4) We can calculate the range through the time interval between sending trigger signal and receiving echo signal.

Formula: uS / 58 = centimeters or uS / 148 =inch; or:

the range = high level time * velocity (340M/S) / 2;

FIRE SENSOR(IR SENSOR)

• The Fire sensor is used to detect fire flames. • The module makes use of Fire sensor and comparator

to detect up to a range of 1 meter. Infrared sensor (1.1 µm and higher) monitors especially the heat radiation of a fire.

• A special frequency range is 4.3 to 4.4 µm. This is a resonance frequency of CO2. The hot CO2 emits much energy at its resonance frequency of 4.3 µm. During burning of a hydrocarbon (for example, wood or fossil fuels such as oil and natural gas) much heat and CO2 is released This causes a peak in the total radiation emission and can be well detected.

Fig 7 : Fire sensor

• In MQ-5 gas sensors the sensing material is a metal oxide(SnO2). Measuring electrode and heater are fixed into a crust made by stainless steel net.

• The SnO2 has lower conductivity in clean air, When the internal heating elements are activated, these gas sensors respond to their specific gas by reducing their resistance in proportion to the amount of that gas present in the air exposed to the internal element.

• A simple electronic circuit is used here which is used to convert the changing conductivity into corresponding output signal of gas concentration.

• MQ-5 is more sensitive towards LPG, Natural gas , Methane and Propane. It is a low cost sensor suitable for different application.

SMOKE SENSOR(MQ-5)

Fig 8: MQ-5 smoke sensor

PICK AND PLACE ARM• This is a wireless remote-controlled robotic arm

with five degrees of freedom, 100g lifting capacity, and an LED light.

• This uses five motors with gearboxes, the Edge has five degrees of freedom: a 120° wrist motion, a 300° elbow motion, a 180° shoulder motion, a 270° base motion, and a 0-1.77" (0-4.5cm) gripping motion.

• When one of the gearboxes encounters excessive resistance to motion, the gearbox will make a noise that alerts you to stop the arm’s motion in that direction.

• Illuminating whatever the gripper is holding, a white LED is mounted to the “hand” of the arm.

RF A/V CAMERA

Fig 9 : RF camera and RF A/V receiver

• RF camera with inbuilt transmitter installed on the robot is used to record and transmit the live video stream.

• A RF A/V receiver is used to receive the video stream

• Received video stream displayed on the PC monitor which is connected to the RF A/V receiver through TV tuner.

EXPECTED OUTCOMESThe sensors are continuously sensing the surrounding

parameters, if any parameters exceeds the set point alarm signal is sent to remote PC .

The related SMS is sent to a mobile phone through GSM modem like, “HIGH GAS” , “FIRE ACCIDENT” etc.

Distance between the obstacle and the robot is calculated using SONAR and the distance is displayed on the screen. Like “Front : distance in inches”.

The velocity of the robot should automatically change as the distance of it from obstacle changes.
