Extra-Curricular Activities
Joint Secretary of Aero-Modelling Club
Gymkhana, Indian Institute of Technology, (BHU)Jul 2016 - May 2017
Under my tenure at the joint secretary of this club, I took the initiative to bring new projects within the purview of the club, and introduced technologies such as racing and autonomous drones. I motivated the freshers of our college to actively participate in the club’s activities by conducting workshops, seminar, and industrial visits. Under my tenure, the club grew in leaps and bounds, and IIT(BHU) witnessed golden days of the club. The visibility of the club grew highly as we participated and displayed our projects at college events, thereby making this club one of the most popular and active clubs at the college. One of the prominent events conducted by our club in Technex went on to receive the best technical event award by the gymkhana for that year.
Head, Ascension
Technex, Indian Institute of Technology, (BHU)Jul 2016 - May 2017
In 2017, our club introduced a dedicated events category called as “Ascension” in Technex, the annual techno-management event of IIT(BHU). I was the head of that event-category, which boasted four prominent and exciting technical competitions related to aero-modelling. We witnessed a high internal as well as external participation in these events, totalling to a footfall of about 600. This activity set aero-modelling club apart from other technical activities and it made a name and a permanent place for itself in Technex for years to come.
Coordinator, Dronetech (Multi-rotor event), Ascension
Technex, Indian Institute of Technology, (BHU)Jul 2016 - May 2017
I was the chief coordinator for Drone-tech, one of the events of Ascension at Technex. This event had the highest prize money of all the events at Technex. This event primarily tests the participants skills in drone making and flying. I, along with my team designed the problem statement for the event. We constructed the arena and organised the event which went on to become a grand success. Even now, the tradition of this event is continued and it remains the event with the highest stakes each year.
Coordinator, Prof. Veerbhadra Mishra Memorial Airshow
Technex, Indian Institute of Technology, (BHU)Jul 2016 - May 2017
Aero-modelling club hosts a very unique event each year during Technex, which displays its technological powress in its full glory. Here, we display many of our flying models and perform exciting feats with them, which are a visual treat for the audience. We see a footfall of more than 2000, including students from various schools, and also professors as well as prominent members of the society. Here, I took up a lead role and led my teams efforts to make this show a grand success. During this year, we displayed new models such as 3D helicopter, racing drone formation, and drone fighting.
