Step 1: 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.
Step 2: 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.
Step 3: Wires
Stick the wires through the appropriate holes and pull them through the body.
Step 4: 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.
Step 5: 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.
Step 6: Appropriate Wiring
Using the female to female wires connect the wires according the diagram.
Step 7: Cleaning Up the Wiring
I used zip ties to clean up the wiring so they could fit a little better inside the body.
Step 8: Add a Trigger
Attach the trigger and stick it through the corresponding hole.
Step 9: Add Battery and Close the Body
After all the wiring is done add the battery source and close it up.
Step 10: Finished Product
This is what my robot ended up but your can add your own designs and creativity.
