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 ...

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 ...

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.

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 ...
