[HoE] Re: Sensors
<<Anyway, as I see it, the various 'human sense' sensors:
Sound:Passive - Microphone, Active - Sonar
Sight:Passive - Camera, Active - Laser tripwire (break the beam, Bye bye
baby!)
Touch:Passive - Pressure plate/Motion sensor (from air pressure)
Active - Can't think of a thing.>>
An active touch sensor could be a device using a jet of air and picking up
changes in the pressure to detect an obstacle.
