STAGE 8: FIT ROBI’S EAR
TRIMS AND SET UP AN
ARM SERVO
Add the two ear trim panels to complete the outer casing of
Robi’s head. Then prepare the servo motor that operates Robi’s
right forearm, and give it the correct identification (ID) number.
To move his arms, legs and head,
Robi is fitted with 20 servo motors (a
diagram showing these is provided in
this stage). Robi’s operating program
needs to know which is which, so each
servo has its own ID number – from
2 to 21. For example, the servo that
moves his right forearm is number 18.
When first supplied, all the servos have
the same ID number, ID=1, so you need
to change each one according to
where it will fit. To set the ID numbers,
you use the test board. This may seem
a little bit complicated the first time,
but it is simple to master if you follow
the instructions carefully.
