Material:

Two OZOBOTs

Card with Path an example is provided

In this activity students will simulate the rotation of two concentrical wheels with different radius: the two wheels have the same angular speed, so the two OZOBOTs must travel aligned on a radius.

Procedure:

• STEP 1

Using the same velocity, measure the ratio between the two trajectories.

or

Measuring the radius of the circumferences, calculate the ratio between the two trajectories.

• STEP 2

Write the code for the OZOBOT, setting the speed in order that the two OZOBOTs, starting from two aligned points, continue travelling aligned.
