Step 1: Making the Body
An assortment of Balsa wood
Step 1: Cut a piece of long rectangular balsa wood that is about 12 x 7 1/2 inches long (this will be the base).
Step 2: Cut two smaller rectangular pieces of balsa wood.
step 3: Cut two long square pieces of balsa wood.
Step 4: Cut two squares.
Step 5: Put the nail into the front and back of both squares.
Step 6: Attach a swivel onto the nails for each square.
Step 2: Finishing the Body
Step 2: Glue each square with the swivel in it underneath the long square rod of balsa wood. Those will be the legs.
Step 3: At the top of each leg put a nail through.
Step 4: Attach the leg to the rectangles on the side of the base using the nails.
Step 3: Mounting the Servo
2 Standard Hobby Servos
Step 1: Glue each servo onto each side of the rectangles attached to the base.
Step 2: String the fishing line through the front swivel on the balsa wood square, then through the servo horn and then through the back swivel multiple times. Make Sure Their is a lot of tension!
Step 3: Do step 2 for each foot.
Step 4: Mounting the Arduino and Wiring Everything
Arduino (I used the arduino mega)
Smaller Nails (or screws)
Step 1: Cut another rectangular piece of balsa wood the same size as the base.
Step 2: Put the arduino mega on that piece of wood and push each nail (or screw) through the mounting hole.
Step 3: Glue the mounting plate to the top of the rectangles on the side of the base.
Step 4: Plug in your servo the the right pins on the arduino.
