Constructing A Flying Drone With A Single Propeller

Technically all that you simply want with the intention to make a drone fly is a single motor and single propeller, however realistically it turns into principally inconceivable to fly it at that time. In the case of helicopters you due to this fact want a second rotor someplace to supply counterbalance to the primary and to have the ability to steer.

There are in fact a lot of methods to make a drone fly with a single helicopter, however the compromise normally is to make use of very giant propellers, in addition to different mechanisms that make for a really giant drone. This wasn’t ok for [Joshua Bird] who needed to have a very small, single propeller drone.

Key to creating it work shouldn’t be solely a really excessive RPM, but additionally a hinged propeller hub that manipulates the  angle of the blades in such a manner that each pitch and roll may be managed if you happen to react rapidly sufficient. This turned out to be inconceivable utilizing customary motor ESCs that don’t immediately measure the motor’s pace and place however depend on again EMF.

In the ultimate prototype of the drone such particulars needed to be measured immediately, with super-fast changes to the motor’s pace solely doable with customized controller code and a whole lot of trial and error. Even then the drone would usually lose observe of its place and crash as soon as extra. The resolution there was so as to add an infrared beacon within the room and a sensor on the drone, to present it a hard and fast reference level.

You can discover the mission information to this point on the GitHub project page, with upcoming adjustments to the drone design involving enhancements like including a scanner to the drone in order that it may possibly autonomously use options in its surroundings as fastened reference factors. That manner it would conceivably have the ability to fly outdoors as effectively, which might be fairly thrilling to see.
