Standard Roamer Comparison

The table lets you compare the programming features of each Standard Roamer.  All Roamers can, for example, use sensors.  So could make Early Years  Roamer into a car, whose headlights turned on if the students programmed it to go into a dark place. The students wouldn’t program the sensors but could enjoy finding out the shady parts of the classroom.
