Researchers from the University of Zurich’s Robotics and Perception Group have proven that this does not need to be the case by keeping a quadcopter flying with only three motors. A quadcopter ...

and four MOSFETs to drive the brushless DC motors. As the PCB also forms the structural frame and landing struts for the quadcopter, not even a 3D printer is needed. All told, [Circuit Digest ...

the authors believe that placing the electrodes closer to the neurones means a higher level of fine motor control. The research participant described the intuitive control of the quadcopter as “like ...
