Handling the Servomotor
1 Orientation
The photo to the right shows theservomotor facing you. There are twoWiderNarrower(drive shaft） （movable shaft）

shafts, the one with the wider space isthe drive shaft and the one with thenarrower space is the movable shaft.
★ When turning the drive shaft by hand,do so very slowly and gently.
Excessive pressure when turning may
cause damage to the servomotor.

2 Calibration and Setting Connector Numbers
Before building your robot, read 6. Using Servomotors in the Studuino
Icon Programming Environment Guide (download fromhttp://www.artec-kk.co.jp/artecrobo/) for instructions on how tocalibrate your servomotor.
Building your robot without calibrating your servomotor may cause
damage or improper functionality.
★ Do not change the connector or the servomotor after calibration.
Servomotor calibrations are unique to each servomotor.

Attaching Number Stickers
After calibration, we recommend putting a sticker on the connector used
for the servomotor so it can be easily identiﬁed.

Operating Your Biped Walking Robot⑥ Turn the switch of the battery box on and your robot will start walking.
Immediately turn the switch to oﬀ if your robot does not begin walking as
shown in the picture below.
Not doing so may damage the servomotor.
If your robot does not move, the servomotor may be in the wrong position or
the blocks may be improperly connected. Re-read the Assembly Instructions
to make sure that your robot has been assembled correctly.

⑦ After the last movement of your robot (raises right hand), your robot will start
walking when it detects a sound.
