Chapter 5 Action Composer
Sound
AIBO can use sounds in WAVE and MIDI
formats for melodies and sound effects, and
import a file made with a commercially
available sound editor to use as a sound
element in Action Composer. Action Composer
is very convenient as you can make MIDI
sounds that are compatible with AIBO without
worrying about format restrictions. You cannot
make WAVE files in Action Composer but you
can import and edit WAVE files.
When a sound is saved, a sound file (.wav or
.mid) will be made.
LED
You can specify the flashing patterns and
brightness levels for AIBO’s body lights (LED).
When LED data is saved, an LED file (.led) will
be made.
Action
An action is a combination of elements.
You can make new actions by changing the
combination of elements or by using newly
created elements. An action does not have to be
a combination of all three elements; an action
can be made of one element only.
The file that manages this combination of
elements is called an action file (.act).
With Action Composer, you can synchronize
the timing of the three elements while you put
them together. For instance, you can make the
LED’s flashing pattern synchronize with the
motion, or adjust the sound and LED elements
to start at the same time.
You can make actions and elements up to 250
seconds long. However, if a motion longer than
30 seconds is played on an ERS-210/220, a great
load will be placed on the motor, so create
actions and elements that are less than 30
seconds long for those models.
Action library
An action library is a group of actions. All
actions used in a single behavior program are
managed by one library.
The file of an action library is called an action
library file (.alb).
When an action library is saved to the “Memory
Stick,” the library is also copied to the PC’s hard
disk and the library contents can be referred to
from Quick Behavior Arranger or Behavior
Arranger. On the “Memory Stick,” the action
library is converted to a format that AIBO can
understand, so this file cannot be edited with
Action Composer.
Note
The system actions provided in Quick Behavior
Arranger or Behavior Arranger cannot be opened or
modified with Action Composer.
