Position In the competition: participated in finals at IIT Bombay and ranked 4th in the theme out

of 55 qualifying teams.

About the Competition:

e-Yantra robotics competition is organized by IIT Bombay and supported by MHRD

Government of India. Main aim of the event is not competition but is to provide students

practical skill set which they acquire on their own by following the instructions of e-Yantra

team after months of hardwork. This year 495 teams were seleted to participate in the

competition. In eYRC+ Caretaker robot Theme 55 teams were selected for the second round out

of which 6 qualified for the finals at IIT Bombay.

About the eYRC+ Caretaker robot Theme:

e-Yantra Robotics Competition Plus has

designed a theme to bring our awareness to the

issue of catering to the needs of patients, for

example, automating the task of serving them,

even in the absence of human supervision.

In this theme, the arena is an abstraction of

a floor in a hospital, which includes a

Corridor, a Patient zone and a Service zone.

The robot is informed of the patients’ requests

via a computer that processes the images from

a camera and it autonomously seeks the

provisions to be picked up and delivered to the

corresponding patients.

Hardware and Software Specification:

4.1 Use of Firebird V robot:

- Firebird V robot based on Atmega2560 microcontroller is used for giving the solution for the

theme.

- The robot should be completely autonomous.

4.2 Components: - 2 Zigbee modules for wireless communication and 3 RGB LEDs.

- Laptop/computer capable of running OpenCV and Python.

- iBall Robocam, web camera for capturing frames for image processing.

4.3 Software Specification:

- ATMEL STUDIO 6, a free software for programming AVR microcontroller or any other open

source Integrated Development Environment (IDE) for programming AVR microcontroller.

- OpenCV and Python to write their code.

Solution provided by us for the theme:

Our solution for the theme is based on single frame of reference that is we are taking a

single image at the starting of the task rather that that multiple images at different time

frames.

That image is processed by us to get a cropped arena clear with provision required and

provisions position. The bot position and orientation is also calculated using a python code.

The position coordinated of the demanded markers and provision markers is calculated

using the python code through Object detection technique.

Now we have Dijkstra’s Algorithm to calculate the shortest path in between the pair of

markers, bot and marker in the arena which in divided in grids with coordinates separated

by 40 pixels.

Now motion of the bot is invoked through the wireless communication as per the shortest

path calculated by Dijkstra’s algorithm.

Bot moves as per the specification specified in the embedded code.

Once the task is complete the python code stops and robot sounds a continuous buzzer

for 5 sec.
