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 ...

According to the team’s results, the BrainGate array wired directly to motor neurons offered a “sixfold improvement” on the user’s quadcopter piloting when compared to an EEG system.

Technically, [B.Aswinth Raj] made a brushless motor, although it isn’t going to fly your quadcopter anytime soon ... to energize the electromagnet. A brushed motor uses a spring-loaded brush ...

The authors believe that to restore highly functional fine motor control, electrodes need to be placed closer to the neurons. The study notes a sixfold improvement in the user's quadcopter flight ...
