Change Roamer into a sheepdog, add a sound sensor and then program it
to respond to whistles. One whistle = turn right, two whistles = turn
left, 3 whistles = wait.
Using a soft ball as a sheep, get Roamer to pen the sheep.

An alternative idea has been sent in by Philip Edwards, Cwmaber Junior
School. He has tried this activity successfully with his pupils and is
keen to hold a local Roamer Sheepdog Trials - any takers?
"Take a small piece of double sied tape and stick it to the front
of Roamer. Unpeel it, leaving a sticky piece on the Roamer. Place a small
polystyrene cup on the floor. If the Roamer touches the cup, it sticks
to the tape and the Roamer can bring it back.
I'd love to see an Inter School competition using this idea."
