They proceeded to remove its battery, add a copper coil to its body, and alter its electronics.<\/p>\n<p>The researchers also built a separate transmitting platform that uses a circuit board, power source and copper coil of its own to produce a magnetic field. When placed near that platform, the drone\u2019s coil acts as a receiving antenna for that magnetic field, inducing an alternating electrical current. The quadcopter\u2019s rejigged electronics then convert that alternating current to direct current, which is used to power its flight.<\/p>\n<p><!-- Link: <a href=\"http:\/\/newatlas.com\/wireless-power-drones\/46030\/\">http:\/\/newatlas.com\/wireless-power-drones\/46030\/<\/a> --><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Given that the battery life of most multicopter drones typically doesn\u2019t exceed 30 minutes of flight time per charge, there are many tasks that they simply can\u2019t perform.
