Cheap Beginner Quadruped Robot

very easy and simple for beginners

Step 1: Parts

for this project your going to need

lego

servo 4x

arduino mega

alot of wires

ultrasonic sensor optional

breadboard optional

cardboard

Step 2: Assembly

so first what your going to want to do is glue the servos at the bottom of the cardboard and then after that you going to want to glue the mini lego legs you made on the servo caps do this 4x after your done that glue your arduino mega on yop and then glue the breadboard and ultrasonic sensor in front of the arduino mega.

here are the wiring

red=5v black=gnd yellow=pin 2 pin 3 pin 4 pin 5

repeat 3 more times of red and black
