DREAM-A-BOT

TECHNOLOGY ROBOTIX SOCIETY

IIT KHARAGPUR

WHAT IS DREAM-A-BOT?

Initiated by TRS last year

Proposals for sufficiently large-scale robotics

projects were invited

The chosen project would receive mentorship,

financial and logistical support from TRS

The first project was The Quadrotor

THE QUADROTOR

A multi-copter propelled by 4 rotors

Used as a UAV in security and surveillance, and

for robotics research

The Dream-A-Bot Quadrotor Project began

recently in Kharagpur

Roadmap has been laid; the rotors have been

tested; and the Inertial Measurement Unit has

been set up

THE WORK AHEAD!

EMBEDDED – IMU interfacing; Brushless DC

Motor Control; Feedback and PID

MECHANICAL – Aerodynamics; Flight Control

PROGRAMMING – Implementation of Flight

Algorithm; Computer Vision for navigation

DREAM-A-BOT 2.0

We are now looking for something centered

around using the Microsoft Kinect as an

integral part of the robot

We will be receiving ideas till June 30

Exact details for submission will be mentioned

later

The chosen idea will be the next Dream-A-Bot

project and the proposer responsible for it.

Image ProcessingBasics

WHAT IS IMAGE PROCESSING?

Accessing the data stored in an

image and working with it is called

Image Processing

WHAT IS AN IMAGE?

It is a 2 dimensional array of pixels with

each pixel having an unsigned value

between 0 and 255.

RESOLUTION

Defines how many pixels are there in the image

If an image has the resolution of [ 800 X 600 ] it

means that the image is a two dimensional

array of size[800][600] that is 800 pixel in the

horizontal direction for each of the 600 pixel in

the vertical direction.

PIXEL

Units which make up the image are

called pixels.

These contain valueS depicting the

shade of the particular cell.

CHANNELS

It is the number of divisions in a particular pixel.

Grayscale images have 1 channel – with value of each pixel

from 0 to 255

Normal colored images (Blue-Green-Red) have 3 channelas, the

shade of each pixel results from the combination of these 3

values.

THRESHOLD

In segmentation, it is the value of a particular channel set by the

programmer which is the border line between the wanted and

the unwanted pixels.

HISTOGRAM

A Graphical representation of the integral value

of the pixels versus the frequency of each pixel.

KINECT FOR WINDOWS

An overview

MICROSOFT KINECT

Senses depth, gestures, motion, sound and much

more.

Natural user

interface.

Lively interaction

with technology.

SENSOR COMPONENTS

HOW DOES IT WORK?

RGB Camera : Makes capturing colour pictures

possible.

IR emitter & IR depth sensor : Gets the “depth” for each

pixel

Multi-array microphone : Possible to record audio as

well as find the location and direction of it.

3-axis accelerometer : Possible to determine the

current orientation of the Kinect.
