There is no need to make them particularly sensitive. I don't
expect you should have any problem with a simple mechanical switch. :)
Remember the comp has feedback on wheel speed, so if we hit an
obstacle too softly to trigger a touch sensor, the comp will still
manager to figure-it-out and will apply more power to the motors until
some touch sensors do go off (or, alternatively, decide that there is
a sensor malfunction of some sort).
_RESOLUTION_ is the most important thing. Ie. There should be a large
number of touch sensors so we can determine the angle at which we
strike an obstacle accuratlely.

I don't believe there is any particular challenge in building this
part of the robot. I leave it confidentally in Cindy's capable hands. :-)
