In order to celebrate our 25th Year Anniversary, United Academy designed an exceptional platform for its students – United Robotics Fest 1.0.

United Robotics Fest 1.0 is a flagship event of United Academy that is being organized for the first time in association with the Robotics Association of Nepal (RAN). It intends to inculcate a scientific temperament in students by providing them with a platform to innovate. It is an amalgamation of several integral components – Workshop, Project Development, Science Exhibition, Robotics Competition, and Panel Discussion.

After going through a rigorous Workshop of 16 hours and a week-long Project Development Phase, 17 teams from United Academy displayed their innovative ideas during a 2 Day Science Exhibition organized at the college premises itself.

At the Science Exhibition, a voting ballot was placed where the attendees could give their votes, the top 3 Robotic Projects were the Smart Dustin, Rain Alarm System, and Soil Moisture Monitoring System.

Winners’ Thought

Let’s hear about the experiences of these winners. United Academy students “Subekshya Karki,” “Subanshana Bam,” and “Fortune Parajuli,” share their thoughts, insights, and feelings below.

“Although we had a lot of interest in Robotics, we were not able to find any platform to learn until we heard about United Robotics Fest 1.0. The mentors explained how Robotics would help us in our careers so we made a team of three and got started. The workshop was very helpful for all of us. The mentors helped us a lot in learning how to connect wires using Arduino and coding.

It was through this experience that we learned how to communicate with others as well. We believe that the opportunity to demonstrate our projects at the Science Exhibition helped us to improve our communication skills.” – Niharika Nembang

“At the exhibition, people came to our stall with a lot of curiosity – nervousness grew inside all our members and initially we hesitated while explaining our project even though we had practiced a lot. After some rounds of practice, we were able to handle the questions of the visitors at our stall. We learned a lot of skills and knowledge. The main point was that it was very helpful for all of us getting to know more about robotics and that we built our communication skills with many unknown people.” – Subekshya Karki

“First of all, we would like to thank the United Academy and Robotic Association Nepal (RAN) team for giving us a great opportunity for showcasing our talent. We did not have any knowledge about robotics at first but when the workshop started we got to know new things and we met new friends. We had really helpful and friendly mentors. They were really helpful throughout the time of the workshop. We spent 6 hours on the first day.” – Sachin Bijukchhe
