Carrying the Olympic Torch


The Roamer team have just been accepted for the next Olympics. They are so keen that they are training 25 hours a day. The Olympic Committee have been so impressed by their hard work and positive attitude that they have said that they can carry the Olympic Torch for the last three stages of its journey.

What you need

  • 3 Roamers with control boxes attached
  • 3 Roamer jackets
  • 3 touch sensors
  • 3 lights
  • materials for design work.

What to do

  1. Change each Roamer into an Olympic sportsperson.
  2. 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.
  3. Attach a touch sensor to the input line on the Control Box and fix it to the back of the Roamer.
  4. Program Roamer to respond to a touch, illuminate the light, move forward, turn off the light.
  5. 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.)

Synchronised swimming

Perhaps not the best known Olympic event, but an ideal one for multiple Roamers. Put them in their swimming costumes, place pegs on their noses and program them to "swim" in formation. (Note - in reality water and Roamers are not a good combination.)

The Olympic Symbol

Try to program Roamer to draw the Olympic Rings. Try to do it within one program.

Hint 1 - You need the pen attachment from the pen pack.

Hint 2 - you will need to change the step size in order to ensure that Roamer moves to the next circle centre point accurately.

Canoe Slalom

Version 1 - Set out your slalom poles for Roamer to go round.

Version 2 - A more difficult version of this would be to have a "two man" canoe. Fix two Roamers together (a loose connection is best - blu-tacked string), then program them both to go round the course together. The different speeds that Roamers move can make this more difficult, as does the fact that the second Roamer will have to travel a slightly different course.

Show Jumping

Create a course for your Roamer horse to go round. This can involve obstacles to go round, ramps to go up and down, see-saws - lots of interesting manoeuvres. The horse that gets round in the smallest number of moves/quickest time wins. You could also then have a dressage competition for the best dressed Roamer horse.


Whilst basically a sprint, by having to follow a curved track this makes it more difficult for a Roamer. Is it better for a Roamer to be on the inside or outside track?
