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-induced emergencies, said a release. The project received essential technical and financial backing from Kokos.AI, whose research and development team worked closely with the students to ensure technological precision and seamless implementation. The group, known as Team Paravai, presented the drone at the recently held SAE Aerothon 2025 in Chennai.Weighing 2 kg, the drone employs a frame constructed from 3D-printed PA12 and carbon fibre composite, allowing for both durability and reduced weight. The quadcopter incorporates several features tailored for real-world rescue scenarios. The aircraft supports communication over a 1-km range, with the capability to stream live video to ground teams. A LIDAR-based collision-avoidance system aids navigation in complex terrain, while onboard sensors enable the detection of human presence from a height of up to 15 metres. The drone can also deliver aid packages of up to 200 grams with high drop accuracy. Its fully autonomous control system reduces the need for continuous operator involvement during hazardous operations, the release said.NIT Calicut officials described the project as a significant step towards enhancing technology-driven disaster management. Team Paravai now plans to expand the drone’s endurance and incorporate advanced payload capabilities.Published - November 22, 2025 09:18 pm IST
