Lesson 6 Advanced Course
Example: The front leg turns
In a movement in which AIBO moves its right front leg all the way
to the back from above, if you add no key frames in between the
starting and ending poses, AIBO may try to move its leg backward
from below.
Though AIBO will be able to do this in the 3D window, in real life,
the front leg will collide with the floor or another part, causing
damage or a malfunction to occur.
If it’s usable, reuse it!
• Reuse anything that you’ve created. It is convenient to put all often-
used key frames and motions into one motion file and name it “KEY
FRAMES.” Copy the key frames in this file when creating new
actions.
• Standing up, sitting down and other motions that change AIBO’s
position are difficult to program, so let’s leave it to AIBO to change
its position. If you feel the need to create such motions, make it
easier to do by copying and referencing the motions from the Sit01
or Stand01 files in the Sample library. The standing-up motion is
more difficult than sitting down since it defies gravity.
Slow down or speed up the motion
• Moving AIBO’s legs and head at the same speed or at a slower or
faster rate produces different effects. You can also produce different
effects by slowing down or speeding up the entire motion. A variety
of effects can be produced merely by changing the speed of the
sample files!
• You can also insert identical key frames to cause a pause in the
motion for greater interest.
Take care with the speed!
• AIBO’s joints move faster than you might imagine, so you shouldn’t
create motions that are too fast. If the speed is excessive, the motion
channel will appear in red.
Increase the number of interval frames or reduce the hinge degree to
adjust the speed.
For details on copying key frames,
see page 84 of the User’s Guide.
