Make an Olympic Torch for each Roamer with a light in it (the Olympic
Flame) that is attached to an output line on the Control Box.
Attach a touch sensor to the input line on the Control Box and fix
it to the back of the Roamer.
Program Roamer to respond to a touch, illuminate the light, move forward,
turn off the light.
Place the three Roamers in a row. Press the first touch sensor so
that the light comes on and Roamer moves forward to bump into the second
Roamer. (Hint: place a wait command at the beginning of the program.)
