    CROW: Now a Farmers Best Friend

October 19, 2017

CROW

CROW was designed for the 2017 Land O’lakes Drone Challenge, where they required teams to be able to record orthorectified crop images, and autonomously determine an appropriate flight path to image a field, after having received a file that has field bounds. It also had to be capable of autonomously operating (i.e. take off, collect data, land, transmit data), as well as function unattended for multiple days, take multiple flights per day, use wireless connectivity to transmit and receive data, operate in winds of up to 32km/h, and use data connection to determine if weather conditions are safe for flight.

The team placed top 3 out of 150 teams worldwide!
