Well not much use given the limited accuracy of GPS over a small area.

Most of the compass sensors draw too much current. However it should be
possible to do something.

This is possible. I am having thoughts...

The problem is that the actual ultrasonic transducers 'limit' the minimum size
this can go to... I am just laying out a PCB for a 'variant' of this unit (I
use a variable current source to return the data, rather than the voltage
source used by most people - requires one more transistor, but reduces current
demand by a noticeable amount - however the unit is still going to have to be
a couple of bricks 'high', just to get the transducers in.

I have been trying to do an inductive sensor that will follow a wire carrying
a particular signal.

I could add a few more. Genuine 'light', rather than covering the brick. A
full 'line track' sensor (I have a couple of quite good prototypes of this).
Lots of ideas...

| Hi ! Increased sensor/motor I/O is a must and do-able. RF would be great, and I don't understand why Cybermaster is RF and the RCX is IR. As far as the sensors are concerned, having been working away on a range of such devices, I am most noticably (...) (27 years ago, 12-Dec-99, to lugnet.robotics)
