This is the final version of our quadruped jeffrey. We have removed the prototype circuit with the boarduino, printed our own circuit. And a protective case has been added on the circuit board. As a final touch we have added sound effects, blinking green eyes and a few random animation to the robot. Plus now the robot is powered by a lithium polymer battery, instead of 4 AAA + 1 9V battery, which decreases its weight and allows it to move faster.
