Our idea: A robot is set up as a postman, and must post a message to another robot. The receiver is one of many robots lined up, and can only be identified by a coloured box in front of them. The postman will then deliver the message to the correct robot via bluetooth. Although we didn’t get time to implement this idea, we found lots of really good tips in how this could work. For example, the use of blocks could be useful, as well as creating parallel routines, and enabling variables as inputs.
