Advanced Control Technology - Inventor Level continued

This is their program:

Note the use of modifiers attached to the icons. This program will loop 56 times and the motor attached to port C will run at full speed.

After completing just one introductory lesson to Inventor Level programming, Class 6F were challenged to write a program to control traffic lights from scratch. This was one of the first amazing attempts by Shelley and Lianne!

Do you think this program is correct? Could it be improved at all?

 

Lucy and Lee made a model using the instructions for a level crossing barrier from the Cities and Transportation set. The children wrote their own program using Inventor level 3, based on ideas we had had during our home security discussions. They used the barrier as "garage doors". When the car driver comes home and approaches his garage, the light sensor opens the door for him to drive straight into the garage. The light then comes on for him to get out of the car and lock up.

This is their program. You will notice two new icons - a red arrow pointing upwards and a red arrow pointing downwards. These two commands work together to create a "jump and land" sequence - in other words, a continuous loop. When the program reaches the upwards arrow, it jumps back and lands at the downwards arrow, starting the program again.
