Project Next Generation: Entry for WeDo Monster Challenge. https://wedo.dreschallenges.com/category/challenges/monsters/ for more info. This monster was fun to watch. However, it only has motion and does not have a sensor. A big problem was that the spinning arm would sometime cause the structure to collapse. Great try though!
I had to redesign my monster’s legs because it would not walk properly. The legs would fall backward, move in opposite directions, and take one step then fall down. This was because one was longer than the other.
