Since robots have to execute a series of user-defined tasks, an additional component is needed. It can also be non-real-time, but it has to ensure the sequential execution of the tasks and has to be able to handle any possible exceptions.

The robot's motions are defined as sequence of steps. The sequencer, which is an integral part of the EEROS Framework, has to be assigned one main sequence. Additionally, several subsequences may be defined and added to the sequencer. Each sequence may include many single steps which must run to completion (unless interrupted by the safety system).
