I'm currently building a $200 drone that kills mosquitoes like a bat. It locates and identifies them with an ultrasonic sonar, and then kills them with a front propeller. It turns out, the drone part is quite simple. 20cm-wide agile quadcopters can be found in every toy shop. The control theory needed to intercept a target is the same as on an air-to-air missile, so is well-known and documented. What's hard is building a 3D sonar able to detect and track a mosquito with a high framerate (mosquitoes are quite agile, and when designing interceptors the main criteria for success is your sensor's refresh speed). This is what I'm working on right now! My sonar uses mass-produced ultrasonic emitters from car park-assist sensors and mass-produced MEMS microphones as ultrasonic receivers. The operating principle is the same as on military radars. It first emits a microsecond-long 40khz ultrasonic pulse. Then, it listens with a 10x10 microphone matrix for echoes and locates them using frequency
