Hey guys, I am curious about the shifting of the drones, they are moving in a way reducing the rotation speed of one motor . So it should lean a bit on a side no? In this case, has not it a taller windage ? And so it will reduce its maximale speed.
Why do not use a system allowing to do spin each motor ? So we will get the maximum of their power in shifting in orienting the motors. The desavantage shoulb be a taller weight.
Thanks.
Guiding and stabilization of drones is typically done by increasing and decreasing the speed of all motors, not just one.
There are constant changes being made to the throttle commands of each motor.
You could handle some of those guiding and stabilization tasks by physically rotating the motors. But there would be several down sides to that.
Mechanical controls would each need another channel controlling them.
Mechanical controls would have some amount of slop, movement in the motor beyond what the mechanical control system intends. This slop is bad for stabilization logic.
I HAVE seen systems that use a servo to pivot one of the motors on a 3 motor drone.
Also, I HAVE seen drones that all 4 motors could pivot forward to transition from hover to forward flight. This was on aircraft made to look like something other than a typical quad copter. It was a lightweight foam aircraft carrier model with the elements of a quadcopter build in to it. It would take off hovering, then the 4 motors would rotate forward and it would change flight mode to forward flight, like an airplane.
But for a standard quadcopter, simplicity means that fixed motors and just changing the speed of all 4 for guidance and stabilization covers all of the flight parameters needed.
