3. Problem Statement
Number of Blind people is nearly 2 million across the
country and almost 6 million are partially impaired. A
mechanism should be developed to help blind people in
their daily activities and able them to move on and freely
anywhere they desire.

4. Problem Statement
 White cane is being used to help blind people but is not
reliable.
Undergraduate Final Year Project Presentation
Dated: 1st April, 2018
 Most popular methods of helping the blind people are
becoming obsolete and thus new method should be
proposed.
 Researchers have addressed the localization problem for
mobile robots using different kinds of sensors including
rangefinders, cameras and odometers.

5. Proposed Solution
 Mapping technique is selected as it ensures:-
• Reliability
• Safety
• Proper path for the visually impaired individual
• Free environment
• Accuracy

8. Applications
 It is used in Blind Assistance
 Can be used in Navigating
 Profitable for industrial work
 Can be used as a spying device with the installation of cameras.

9. Audience
• Our Target audience is university/college students.
• Their main issue is navigation
• Occasionally they wander off their path
• They have to walk in groups for a reason
• This device will prove more time efficient to them
• The blind people in the orphanages
• People in the Hospitals

10. What we have done so far?
 IEEE Research Papers
 Gave the map to the robot and successfully made it to
follow that map.
 Tested the home automation system .
 Software
• Visual Studio
• Keil u Vision 5
 Hardware (Body of robot, Home automation control)

11. Hardware Developed
Undergraduate Final Year Project Presentation
Dated: 1st April, 2018
• Sensors are present on each
side of the robot to avoid
obstacles.
• Map is given by the user by
the help of a pushbutton.
• Two separate push buttons are
present ,hence the user is able
to follow two separate maps
on the same time.

12. Hardware Developed
• Map is coded into the robot
• Push buttons choose the map to be
followed
• Speed is nominal as it has to guide a
blind person
• Mapping area is kept flexible ,hence
any map can be fed into the robot.

13. Hardware Developed
• Home Automation has been done by
GSM Module
• Programming has been done on TIVA
• The user uses mobile phone to send a
voice command
• Resultantly ,the home appliances are
controlled

14. Future Deliverables
 Classifying objects and letting the users know what
kind of obstacle was encountered.
 Visualizing the text and reading it out in the ear piece.
 Can be used at a broader level (walking in housing
societies etc.)
