and upon running into something will fire off a projectile (using the
small "gun" and rubber tipped "bullet" that comes with the RDS) then turn • and
flee.


I agree with the second post: Have the collision trigger both the touch • sensor
and the firing mechanism.  This leaves both motors free to drive

Except that you need a motor to trigger the firing pin, unless you do some
sort
of mechanical linkage which would make the front bumper a trigger...

The L3GO from the DDK has a single-motor driving the left front wheel, the
right front wheel is just on an axle, while the rear wheel is a caster wheel
that has a very limited travel, when you drive the motor forward, the caster
wheel
pulls straight, and the robot travels straight, when you reverse, the wheel
swivels
*slightly* to make the robot turn.  Pretty cool engineering actually.

(...) You might be able to do just that and link the bumper directly to the firing pin. Once that is put together and working, position the touch sensor on the firing mechanism so that it is always depressed. When the gun goes off, the touch sensor (...)

Using the differential will work fine (although I'm not sure if it comes in the RDS or (...) (24 years ago, 30-Dec-99, to lugnet.robotics)
