The Scanning Tunnelling Lego
The Probe is a Lego MindStorms
robot that can determine the height of each point of an object on a grid.
It does this by scanning a head back and forth along the x-axis, moving a
little along the y-axis after each scan. For each point along the way it
stops and lowers the probe (a long axle) until it makes contact with the
object. Counting the time it took to lower the probe gives a measure of
the depth at that point. These depth values are logged and transmitted
to a NetWinder
Linux box for plotting.
