A group of students from the National Institute of Technology, Calicut (NIT-C) has developed an autonomous quadcopter that can be used for search and rescue missions.
Formed in August, the 15-member team set out to design a compact aerial system capable of assisting rescue agencies during floods, landslides and other climate-related emergencies. The project received critical technical and financial support from Kokos.AI, whose research and development team worked closely with the students to ensure technological accuracy and seamless implementation. A group known as Team Paravai showcased the drone at the recently held SAE Aerothon 2025 in Chennai.
Weighing in at 2kg, the drone uses a frame made from 3D printed PA12 and carbon fiber composite, allowing for both durability and lower weight. The quadcopter includes several features tailored for real-world rescue scenarios. The aircraft supports 1km communications with the ability to stream live video to ground teams. A LIDAR-based collision avoidance system aids navigation in difficult terrain, while on-board sensors allow detection of human presence from up to 15 meters high. The drone can also deliver aid packages up to 200 grams with high drop accuracy. Its fully autonomous control system reduces the need for continuous operator involvement during hazardous operations, the report said.
NIT Calicut officials described the project as a major step towards improving technology-based disaster management. Team Paravai now plans to extend the drone’s endurance and incorporate advanced payload capabilities.
