Abstract - Cloud robotics is a field of robotics that attempts
to invoke cloud technologies such as cloud computing, cloud
storage, and other Internet technologies centred on the
benefits of converged infrastructure and shared services for
robotics. This paper is a study of cloud robot which is used in
industrial and manufacturing environment. It works onaROS
platform. Here a Raspberry Pi controller is used to control the
various devices attached to it. For testingthis implementation,
Android phone, camera, DC motor, sensors and a Raspberrypi
controller have been used. The movement of the robot is
provided by DC motors and the direction is controlled from an
android environment using Robot Operating System (ROS).
The controller and the receiver end is connected by Wi-Fi. The
data input from the gas, temperature and Infra Red sensors is
given to the Raspberry Pi controller. A camera is used to
provide visual input of the surrounding environment to the
robot. The data obtained by the sensors and camera are
processed by the controller and stored in cloud.
Keywords:- ROS, Cloud robotics, Raspberry Pi
1. INTRODUCTION
With the advances in technology, a new area called Cloud
Robotics (CR) has evolved from conventional roboticswhich
can create a wide impact in industrial areas. When
connected to the cloud, robots can benefitfromthepowerful
computational, storage, and communications resources of
modern data centre in the cloud, which can process and
share information from various robots or agent (other
machines, smart objects, humans, etc.). The goal is to
construct a robot with sensorsandalertsystem whichworks
within the control of cloud. To make this work, a separate
platform for the robot is needed to work on which is, the
ROS- Robot Operating System.
Robot Operating System (ROS) is a collection of software
frame works for robot software development providing
operating system-like functionality. ROS provides standard
operating system services such as hardware abstraction,
low-level device control, implementation of commonly used
functionality, message-passing between processes, and
package management.
2. EXISTING SYSTEM
Existing industrial control and monitoring systems have a
significant portion of their costs in cable installation and the
maintenance costs associated with moving and replacing
cables during machinery maintenance and re-configuration.
2.1Wired device
Wired devices are fixed to or near the machinery. These
devices are wired to power supply. The lack of wireless
system and large power consumption are the drawbacks of
wired device.
Disadvantages- fixed in particular place, cost, cable
installation, maintenance.
2.2 Manual system
Manually control the devices inside the industry.
Disadvantages-Lack of wireless communication (e.g. - RFID,
ZIGBEE). Large power consumptioninordertoautomatethe
entire industrial system.
3. PROPOSED SYSTEM
The above disadvantages have been eliminated in the
proposed system. In this method, we a locomotive Cloud
Robot is introduced. A Raspberry-pi controller is used in the
robot to control its movement. The directions are controlled
by an android device or computer using ROS.
A Robot Operating System (ROS) allows a user to easily
control the mobile operations of a robot. A Camera isusedto
give input to the Raspberry pi microcontroller.Temperature
sensor and gas sensor is used to sense the temperature and
gas leakage with the use of Raspberry Pi controller.
An IR sensor is used to alert attempt to access restricted
area. An alarm system with a dangerindicationlamp,cooling
fan and speaker alert are fixed with the Raspberry Pi
controller. Wi-Fi is used to send the data from controller to
Mobile using the IP address of the Raspberry-Pi kit. Using a
mobile, the robot movement can be controlled. The
monitored data will be sent to the cloud enabling access of
information from anywhere.
3.1. Transmission Section
3.1.1 Raspberry Pi
This credit card-sized single board computer is a fully
programmable PC that runs in open-source Robot operating
system. The board consists of Video Core IV graphics

processing unit (GPU), ARMv7-compatible quad-core one,
512 MB of RAM. It has a MicroSD to boot media and for
persistent storage.
One powerful feature of the Raspberry Pi is the rowofGPIO -
General Purpose Input/output pins along the edge of the
board (refer Fig.1.1). These pins are a physical interface
between the Pi and the outside world. At the simplest level,
these are called as switches. Seventeen of the 26 pins are
GPIO pins; the others are power or ground pins.
Fig. 1.1 Example for Raspberry Pi connectors.
3.1.2. Sensors
I. Temperature sensor- The DS18B20 Digital
Thermometer provides 9 to 12-bit (configurable)
temperature readings which indicate the
temperature of the device. Information is sent
to/from the DS18B20 over a 1-Wire interface.Itcan
be powered from its own data line. Power supply
range is from 3.0V to 5.5V. It measures
temperatures from - 55°C to +125°C. It has 0.5§C
accuracy.
II. IR sensor- These are miniaturized IR receiver
modules for remote control systems. The sensors
detect the wavelength and spectral radiation of the
light from the IR emitter. It provides high
communication speed and high level of security.
III. Gas Sensor- It is used in gas leakage detecting
equipments the industry. It is suitable for detecting
of LPG, iso-butane, propane. It had Small sensitivity
to alcohol and smoke. Highlighting features include
Fast response and Stable and long life. The sensor
can be directly powered by DC supply or through a
diver circuit.
3.1.3. Camera
The type of camera used here is an IP camera which has
recording function built-in and can thus record directly to
any standard storage media, such as SD cards, NAS
(network-attached storage) or a PC/server. The camera
feeds or streams its image in real time to a computer or a
mobile using network. When "captured" by the computer,
the video stream may be saved, viewed or sent on to other
networks via Wi-Fi. When sent to a receiver side, the video
stream is saved in cloud.
The resolution offered by the camera is 1280x720 (720p)or
even 1920x1080 (1080p) resolution. The video stream is
viewed in mobile or computer by connecting to the IP of
Raspberry Pi controller kit.
3.1.4. Power supply
There are several ways to convert an AC voltage into the DC
voltage. Traditionally, this has been done witha transformer
and rectifier circuit.
However, in applications that involve providinga DCvoltage
to only the controller and a few other low-current devices,
transformer-based or switcher-based power supplies may
not be cost effective. So, Transformer less power supplies
which provide a low-cost alternative to transformer-based
are used in this robot. A transformer less power supply
typically incorporates:
 Rectification
 Voltage Division
 Regulation
 Filtering
 Inrush Limiting

3.2. Receiver Section
3.2.1. Alarm system
i. Cooling fan- the robot is fitted with a cooling fan which
turns on when the temperature sensor detects a reading

which is more than the desired value. The fan is focused in
the area where the temperature dissipation is more and
cools the area. It is powered by DC supply.
ii. Indication lamp- The light source powered by DC supply
automatically turns on when the IR sensor detects access to
restricted area. The lamp glows when IR receiver senses
undesirable access into a particular area.
iii.Speaker alert- In case of emergency situation, say here a
gas leakage, the gas sensor detects the presence of harmful
gas in the environment and signals the controller. The
controller in turn switches on the Speaker alert.
3.2.2. Cloud
Cloud computing is a synonym for distributed computing
over a network. Its highlighting feature is the ability to run a
program on many connected computers atthesametime.Its
advantages proved in history include on-demand self-
service, ubiquitous network access, location independent
resource pooling, rapid resource elasticity, usage-based
pricing and transference of risk. Some oftheServicesoffered
by cloud include 'SaaS' (Software as a Service), 'PaaS'
(Platform as a Service), 'IaaS' (Infrastructure as a Service),
'HaaS' (Hardware as a Service) and 'NaaS' (Network as a
Service).
3.2.3 DC motor
The DC motor is connected to a set of four wheels and is
responsible for the movement of robot. A DC motor is a class
of electrical machine that converts direct current electrical
power into mechanical power. A DC motor's speed can be
controlled over a wide range, using either a variable supply
voltage or by changing the strength of current in its field
windings.
3.2.4 Wi-Fi (Wireless Fidelity)
Wireless Fidelity or Wi-Fi is a local area wireless computer
networking technology that allows the Raspberry Pi kit to
connect to the network. It uses a bandwidth of 2.4 gigahertz.
The Wi-Fi network provides the connection of unique IP
address from the Raspberry Pi kit to the devices in receiving
end. Using the various encryption technologies in Wi-Fi, the
network is made secure.

4. OPERATION
A robot is designed that can move and monitor the entire
industry from the inside. The movement is provided by
wheels attached to the DC motor. Wheeled robots are the
most energy efficient and simplest to control. The motor is
controlled by the Raspberry Pi controller.Thecontroller and
the mobile or computer at the receiver station is connected
by a unique IP address. Thereforethemovementofthe robot
is controlled by the person at the receiver side by operating
in a separate platform called the ROS- Robot Operating
System. The live video feed obtained by the camera is
streamed to the receiver and viewed in the screen.
In robot, If Temperature level increases above the threshold
value then the controller switches on the cooling fan. If Gas
level increases above the threshold value thenthecontroller
invokes the speaker announcement. IR sensor signals if a
person is trying to cross a restricted area and switches on
the lamp. All the data obtained in mobile is uploaded to
cloud. The uploaded information can be viewed, saved from
anywhere by entering the IP address.
Wi-Fi is provided for the entire process by a Wi-Fi dongle
which is fitted along with the robot. The power supplyfor all
the components is provided by DC transformer less power
supply.
