Smart Sensors or Intelligent Sensors are sensors that incorporate a microprocessor or microcontroller. They usually compensate for environmental disturbances and have built int ADC's and comunications systems by digital buses. \n\nGoogle Intelligent Sensors

Oxygen sensor for what? Cars ?

did you mean how does a light sensor work?

You wont be able to read SMART attributes for a USB device because they don't exist. The SMART technology is built onto a small board on the bottom of Hard Disk Drives - sort of like a mini-motherboard. USB devices aren't really "drives" although they use a similar protocol in order for the OS to acknowledge the device.

rotational sensor.. which is basically an inductive prox with a timming circuit to calculate revolutions.

sure. go to a science store or look up schematics on the web.

look on the top of the controler, near the wire or sensor.

If you need laymans details, then I'm thinking that the use of Gyro's may be beyond your abilities as far as robotics are concerned. You may be better off constructing a robot with wheels ( take a look at the kits available at www.jameco.com )\n\nGyro's are expensive, precision instruments that require interfacing to microprocessors to obtain and process any useful data. Another sensor that could do something similar and would be cheaper and easier to use, would be an accelerometer which has an output that may be easier to interface with. \n\nHope this helps

Your best bet is to contact a company that specializes in this sort of thing. I've got a number of websites below that you could start with which would explain and provide links to helpful information.\n\nThere is software, but hardware is also needed. It is available in the USA, but I can't speak for the rest of the world.
