The disaster relief operation launched in response to catastrophic flooding in India's Uttarakhand state included the use of an indigenously-developed unmanned air system.
Developed by Mumbai-based company Ideaforge, in collaboration with the nation's Defence Research and Development Organisation, the quadrotor was employed by Indian security forces during the aftermath of the natural disaster in mid-June. Three Netra air vehicles were involved in the effort, according to local media reports.
Weighing around 1.5kg (3.3lb) and with a 30min flight endurance, the vertical take-off and landing Netra is controlled from a laptop, using what the Ideaforge describes as an "intuitive, point and click graphical user interface".
Imagery collected by the Netra air vehicles assisted relief efforts by India's National Disaster Relief Force, by locating survivors in territory cut off by landslides.
