Connect Servers
Add servos to both feet and to the body. Make sure you screw them on with the small screws to keep them in place.
Add the Legs
Attach the legs to the body also tightening it to the body. Make sure the legs are able to rotate 180 degrees.
Wires
Stick the wires through the appropriate holes and pull them through the body.
Snap in the Feet
Once you pull the wires through the holes make sure the feet click in and then screw the feet in place with two more screws.
Add Your Software
First insert your ultrasonic sensor to create the eyes. Now, attach the ATmega 328 to the Nano shield I/O and place inside the head of the robot. Make sure the outlets align with the corresponding holes.
Appropriate Wiring
Using the female to female wires connect the wires according the diagram.
Cleaning Up the Wiring
I used zip ties to clean up the wiring so they could fit a little better inside the body.
Add a Trigger
Attach the trigger and stick it through the corresponding hole.
Add Battery and Close the Body
After all the wiring is done add the battery source and close it up.
