This document describes a gesture controlled robot project. The objective is to create a simple and inexpensive robot that can be controlled through gestures. The robot uses an accelerometer sensor to detect hand movements, which are then wirelessly transmitted via radio waves to the robot. The robot receives the signals and moves in the corresponding directions. The system includes a transmitter section with an accelerometer, comparator, and encoder, and a receiver section with a receiver, decoder, and microcontroller that controls motors to move the robot.
Project Report on Hand gesture controlled robot part 2Pragya
A gesture is a form of non-verbal communication in which visible bodily actions
communicate particular messages, either in place of speech or together and in parallel
with words. Gestures include movement of the hands, face, or other parts of the body.
Gestures differ from physical non-verbal communication that does not communicate
specific messages, such as purely expressive displays, proxemics, or displays of joint
attention. Gestures allow individuals to communicate a variety of feelings and
thoughts, from contempt and hostility to approval and affection, often together with
body language in addition towards when they speak.
Gesture Controlled Robot is a robot which can be controlled by simple gestures. The
user just needs to wear a gesture device which includes a sensor. The sensor will
record the movement of hand in a specific direction which will result in the
movement of the robot in the respective direction. The robot and the Gesture device
are connected wirelessly via radio waves. The wireless communication enables the
user to interact with the robot in a more friendly way.

Obstacle Avoiding Robot
Robotics is a branch of science that deals with Mechanical, Electrical and Software fields. Robots are the machines that are used in our day-to-day to life to reduce men power and work accurately without any distortions. Robots can be classified into two different sections basing upon their skills as Automated and Manual. Obstacle detector is a Automated robot which itself recognizes the obstacle in its path and moves in free direction. Robot detects the obstacle by using two IR Sensors placed in front.
The IR sensors are placed on left and right side of the robot through which continuous Infrared radiation is emitted for detection of obstacles in the path. These IR Sensors are connected to a controlling element AT89c51 µc. When a obstacle is placed in the path of robot IR beam is reflected to the sensor from the obstacle. On detecting obstacle in the path sensor sends 0 volts to µc. This 0 voltage is detected by Microcontroller which avoids the obstacle by taking left or right turn. Similarly if the sensor sends +5v to Microcontroller, the Microcontroller assumes it as clear path and makes the robot to move in straight.
Two motors namely right motor and left motor are connected to Motor driver IC (L293D). L293D is interface with Microcontroller. Microcontroller sends logic 0 & logic 1 as per the programming to driver IC which makes motors to rotate in clockwise and anticlockwise direction. Wheels attached to the motors rotate accordingly with the motor shaft causing in the moment of the robot by wheels. In front portion of the robot a free wheel is attached to move the robot easily in any direction as per the requirement.
A 12Volts DC battery is attached to the circuit. As the microcontroller and sensors requires only 5v, set of resistors and capacitors are used to supply 5v DC to them. Power Management System is not maintained in the circuit as the battery can be removed after the usage of robot. So it does not cause any loss in the power of battery.
This type of robots has multiple applications in various fields. They can be used to know the strength of the opposite army in defense system. They can be used as floor and wall cleaners. They are used in automated GPS vehicles to calculate the moment of the vehicle overhead. These robots are easy to construct and cheaper in cost with long durability.
it is basically a model for wheelchair.for physically handicapped persons it will be very useful.the robot uses a accelerometer sensor for the movement of the robot, so that sensor is installed on the transmitter section and the thing you should wear on your arm.on the receiver side microcontroller is present which will decode the data.

Bi directional speed control of dc motor and stepper motor through mat lab us...eSAT Journals
Abstract In any industry speed control of an electric drive system is very critical and crucial. Every designer aims at achieving a control methodology having high degree of precision. But industry needs are ever evolving in nature. Hence it is very much essential that along with conventional speed control mechanisms we must also have simple interactive graphical based control strategies. Several algorithms/methodologies have been developed over the years to achieve speed control of motors. In this context by encompassing the usability of Mat Lab, work has been done to control the speed of stepper motor and DC motor using microcontroller. Microcontroller is programmed to achieve bi directional speed control. The main objective of this work is to develop the graphical user interface of motor control through mat Lab guide and the interface of the same with hardware via serial communication. PIC is used as the controller. Keywords— DC, PIC, μC, AC, GUI, IC

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

Courier management system project report.pdfKamal Acharya
It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

An Accelerometer is an electromechanical device that measures
acceleration forces. These forces may be static, like the constant
force of gravity pulling at your feet, or they could be dynamic –
caused by moving or vibrating the accelerometer. It is a kind of
sensor which record acceleration and gives an analog data while

8. • COMPARATOR IC (LM324)
The comparator ic compares the analog voltage received from the
accelerometer and compares it with a reference voltage and gives
a particular high or low voltage. The received signal is quite noisy
and of various voltage levels. This ic compares those levels and
outputs in the form of 1 or 0 voltage level. This process is called
signal conditioning. The figure shown below is comparator IC. The
pins 1, 7, 8 and 14 are output pins.

18. • MOTOR DRIVER IC (L293D)
• It is also known as H-Bridge or Actuator IC. Actuators are those
devices which actually gives the movement to do a task like that
of a motor. In the real world there are different types of motors
available which work on different voltages.

19. Electronics & Communication, SCE 2014 – 15 19
Turning a motor ON and OFF can be achieved by using four switches that are arranged in an
intelligent manner such that the circuit not only drives the motor, but also controls its direction. The
most common and clever design is a H-bridge circuit where transistors are arranged in a shape that
resembles the English alphabet "H".
Gesture Controlled Robot
20. • As seen in the image, the circuit has four switches A, B, C and D.
Turning these switches ON and OFF can drive a motor in different
ways.
• When switches A and D are on, motor rotates clockwise.
• When B and C are on, the motor rotates anti-clockwise.
• When A and B are on, the motor will stop.
• Turning on A & C at the same time or B & D at the same time
shorts the entire circuit. So, never try to do it.

21. DC MOTORS
• A machine that converts DC power into mechanical power is known as
a DC motor. Its operation is based on the principle that when a current
carrying conductor is placed in a magnetic field, the conductor
experiences a mechanical force.
• Different connections of the field and armature winding provide
different speed/torque regulation features. The speed of a DC motor
can be controlled by changing the voltage applied to the armature or
by changing the field current.

22. DC GEAR MOTOR
• A geared DC Motor has a gear assembly devoted to the motor. The
speed of motor is counted in terms of rotations of the shaft per
minute and is termed as RPM .The gear assembly helps in increasing
the torque and dropping the speed. Using the correct arrangement of
gears in a gear motor, its speed can be reduced to any required figure.
This concept of reducing the speed with the help of gears and
increasing the torque is known as gear reduction.
• Reducing the speed put out by the motor while increasing the quantity
of applied torque is a important feature of the reduction gear trains
found in a gear motor. The decrease in speed is inversely relative to
the increase in torque. This association means that, in this sort of
device, if the torque were to double, the speed would decrease by one
half. Small electric motors, such as the gear motor, are able to move
and stand very heavy loads because of these reduction gear trains.
While the speed and ability of larger motors is greater, small electric
motors are sufficient to bear these loads.

24. Methodology
• The transmitting device includes a Comparator IC for assigning
proper levels to the input voltages from the accelerometer and an
Encoder which is used to encode the data and then it will be
transmitted by an RF Transmitter module.
• At the receiving end an RF Receiver module will receive the
encoded data and decode it by using a decoder. This data is then
processed by a microcontroller and passed onto a motor driver to
rotate the motors in a special configuration to make the robot
move in the same direction as that of the hand.
