Inventor Level 4

Introducing Containers

At the top menu select Tools or Project (depending on version) and scroll down to Change Inventor Level. Choose Inventor

level 4.

This level gives you access to all the ROBOLAB programming icons and lets you make very advanced and complex pro-

grams. You can explore the possibilities by using the Context Help menu or see the Using ROBOLAB guide, which you can

purchase along with the software.

Three new sub-menus called Reset, Containers, and RCX communications appear. (Please note that there are an addi-

tional 8 sub-menus in ROBOLAB 2.5.)

Container Icons

Introducing Container Commands

A Container is an icon that stores a value and tells the program when to send that value to another programming icon.

Within the Container the value can be multiplied, divided or subtracted.

1. Use your two motored vehicle. Make sure the lamp is connected to output port B. You will not be using the motor or

touch sensor.

2. Delete the program on your screen and copy the string below. For this challenge you will need the Container Fork icon

to tell the robot how to distinguish between the value stored in the container.
