Connecting the boxes to loop the

program

By connecting the boxes in a loop, you can make the program one

continuous motion.

1 Check the head sensor for input every second

1 Set the mouse to link mode, and then connect

the STAND and TOUCH_HEAD? boxes.

2 Connect the lines to make a loop as follows:

1 Connect the free terminal of the TOUCH_HEAD? box to the

input terminal of the WAIT_1SEC box.

2 Connect the output terminal of the WAIT_1SEC box to the

input terminal of the TOUCH_HEAD? box.

The WAIT_1SEC action box loops and checks the input to the

head sensor every second when AIBO has not received any

input.

If the mouse is in normal mode,

you can also connect the boxes by

clicking and dragging the mouse

while pressing the shift key.

When connecting the branch box

to the box that is the jump

destination, confirm the condition

of the terminals before connecting

the box to the correct destination

box. The branch condition is

displayed when you place the

mouse on the terminals.

By connecting the empty terminal

(ELSE) to WAIT_1SEC, you’ve set

the following condition:

“If the head was not pressed” t

Wait for 1 second (jump to the

WAIT_1SEC box).”

Checks for input to the

head sensor every

second.
