Students at the Indian Institute of Technology (IIT) Madras have developed a “smart agricopter” to eliminate manual spraying of pesticides in agricultural fields and help identify crop health by using a imaging camera. The innovation will allowing spraying pesticides ten times faster and with 100 per cent precision at the same cost as manual spraying. “The advanced multispectral imaging camera allows the hexacopter drone to make smart maps of farmland based on crop health and its completely autonomous pesticide refilling system ensures entire spraying is completely autonomous.
