Jam condition
If something gets jammed in any of the joints of
AIBO, AIBO changes to this condition and all of its
joints become loose. This mode is provided to protect
your fingers from being caught between the joints of
AIBO.
To return AIBO to Autonomous mode, place it on the
floor and push the head sensor in the back direction
for 3 seconds.
