The BQM-1BR was a Brazilian
unmanned aerial vehicle
An unmanned aerial vehicle (UAV) or unmanned aircraft system (UAS), commonly known as a drone, is an aircraft with no human pilot, crew, or passengers onboard, but rather is controlled remotely or is autonomous.De Gruyter Handbook of Dron ...

Design and development
The BQM-1 BR was the first remotely controlled vehicle built in Brazil by the Companhia Brasileira de Tratores (CBT) in partnership with the

In vascular plants, the roots are the plant organ, organs of a plant that are modified to provide anchorage for the plant and take in water and nutrients into the plant body, which allows plants to grow taller and faster. They are most often bel ...
