3 things: sensors, actuators/motors, controllers.
Sensors: measure the environment
actuators/motors: chance the environment
controllers: input, output, software.
If you want your zoo of bricks, it's really a set of sensor/controllers
or motor/controllers. You can do this today w/ scout+motor or RCX+sensor,
but the thing you want is prolly smaller than an RCX package. So you also
want a tiny controller (1 in, 1 out, plus comm i/o) to go with a sensor;
else a tiny sensor+controller thingy, which would be a sensor with
embedded stripped-down controller.
Either way, it's all the same thing. Getting them to behave, on the other
hand, it an altogether different issue (simulations with StarLogo?)
