Chapter 17. using multiple sequence beams > multitasking
17.1. multitasking
Multitasking means doing more than one thing at a time. You use multitasking in a program to make your robot perform two (or more) independent tasks simultaneously. For example, your program could have one section to control the robot’s navigation and a separate section to collect sensor data.
In NXT-G, multitasking is accomplished using multiple Sequence Beams. Figure 17-1 shows an example based on the AroundTheBlock program introduced in Chapter 4. The blocks on the Sequence Beam at the top of the program move the TriBot around a square, and the blocks on the Sequence Beam at the bottom continually display the motor position.
