Step 14a.

It is likely that when you assembled the legs, 
the positions were not exactly at 90 degrees. 

You have two options to position each of the 
servos, the first of which is to use Lynxterm. 

Download and install Lynxterm (software 
section under "Products"). Disconnect the SSC-

32 from the BotBoarduino and reinstall the Tx / 
Rx jumpers, as well as both Baud jumpers (so 

it's at 115200). Power the SSC-32 (both VL 
and VS), open Lynxterm, select the correct 

COM port and click "All=1500". The servos 
should all move to 90 degrees. Next, click 

"Reg." and in the new window, click "Read". 
Position each servo to exactly 90 degrees by 

using either the slider or by typing in the 
offset. Once this is done, click "Write", which 

then modified the firmware on the SSC-32.

Step 14b.

Instead of using Lynxterm to position the 

servos at 90 degrees, you can use the SSC-
32's built-in position offset feature. Please 

refer to the SSC-32 user guide for more 
information. You will need to add the position 

offset commands in the sample code.

Step 14c.

If you have FlowBotics Studio, pair with the 

Bluetooth module via the FlowBotics Studio 
SQ3 project interface. The green light on the 

Bluetooth will become solid once a connection 
has been established. Click the "configure" 

button to position each of the servos to exactly 
90 degree.

Step 15.

The robot should now be wired correctly, but 
there with wires going everywhere. It is now a 

matter of routing the cables. You can unplug 
and re-plug the wires as needed, especially for 

the servos, and well as run them through the 
body and brackets. Be certain to leave enough 

length so each joint in the legs are able to 
move freely and reach all positions and do not 

get pinched by the brackets or servos. Use the 
cable ties provided in the kit to connect the 

wires together. Alternatively, black electrical 
tape or wire wrap also look nice.

Ensure the battery is perfectly centered inside 

the body to ensure the robot walks properly.
