e-Yantra Lab Setup Initiative (eLSI) : 2 Day's workshop on "Introduction to Robotics"
10th - 11th June 2022
e-Yantra Lab Setup Initiative (eLSI) : 2 Day’s workshop on "Introduction to Robotics" was organized by Indian Institute of Technology (IIT Bombay) on 10th - 11th June 2022. The workshop was scheduled for only faculty members and it was completely hand-on session on Fire Bird V robotics module. Dr. Hari Mohan Rai, from Dronacharya Group of Institutions, Greater Noida attended the two-day workshop at IIT Bombay on 10th - 11th June, 2022.
Day 1: 10th June2022:
The workshop was started with inauguration – lighting of Lamp. Then Prof. Dr. Kavi Arya, (In -charge e-Yantra workshop), presented an overview of the e-Yantra Robotics Initiative. The members of the e-Yantra team then began the session by presenting the Fire Bird V Robot. This is essentially a Robotic Research Platform, and it offers an environment for testing, developing algorithms, and conducting experiments. Because of its modular design, user is able to exercise control over utilizing a variety of processors, including 8051, AVR, and ARM 7. IIT Bombay provided ATMEGA2560 Kit with all of the necessary accessories to every participants to perform the hands on session from the beginning of the workshop. Then, Mr. Vivek, a member of the e-Yantra team at IIT Bombay, introduced the AVR Micro-controller. Micro-controllers based on the ATMEGA2560 were used throughout the session. With the assistance of the team, participants were able to identify the components of the Fire Bird V robot.
During the hands-on practice that took place in the afternoon, participants started by developing the code using embedded C programming. First, participants conducted a basic experiment on "Buzzer On" making use of a Fire Bird V Kit and an Interfacing cable. The first thing that needed to be done was to use the embedded programming to turn on and off the buzzer that was built into the robotics module. After that, the true hands-on training could begin. Similarly, participants have completed the second experiment, which consisted of controlling basic motion via I/O ports. Next participants, continued with the third experiment, which included utilizing pulse width modulation to control the speed of a robot (PWM). The experiment was modified such that a run of the robot could be made along the line of a square and a circle as the fourth experiment. Every single participant has received assistance from the other members of the team in order to operate the robot in accordance with the experiment.
Day 2: 11th June 2022
The session for day 2, started with the description of interface of LCDs, also known as liquid crystal displays. The experiment was carried out in conjunction with a theoretical discussion and practical training. After that, an ADC, which stands for analog to digital conversion, was used to kick off the session. During the discussion, participants gained knowledge about white line sensors as well as their connection. During the session, participants had some difficulty, but the organizers helped to get over it so that participants could successfully complete the experiment. The discussion focused on the means through which the robot may be forced to follow a specified white line. Along with the interface kit and the robot, they have also given white line and black line chart paper. Everyone is required to operate their robot completely inside the white line without deviating in any way. After the software was created to meet the requirements and successfully interfaced with the laptop, everyone in the group was able to complete the experiment successfully.
Later participants jumped right into the topic with the subject of Interrupts. The theory behind interruptions and closed loop control of robots via the use of position encoders has been covered in the lesson. The topic of discussion for the session is how user can build the precise square route follow up of robot with precision and without using any form of approximation or trial and error. At last, the experiment using position encoders to locate the location of the white line following robot has been tried, participants are ready to discuss the results.
At long last, everyone arrived at the culminating phase, which was the beginning of the valediction ritual. All of the participants have been awarded their certificates by Prof. Dr. Kavi Arya.
The e-Yantra Hands on session that took place over the course of two days at IIT-Bombay was ultimately effective and proved to be of great use.
