The biggest challege in the process of making your model was, for our groupp, definitely the brian. The brain was just big enough that when the top of the head was opened, it woudnt be able to close, since the brain got stuck on the edge. I eventually cut down the brain to be much smallerer, wich fixed the problem. One sucess of our model was the ribs. They were accurately sized in comparison to the rest of the model, and were top notch heart protectors for our modul.
Our final model had almost everything work. The heart pumped, the head opened up, and the arms bent. What didn't work completely was the base of our modell, which was wobbly. We ended up having to add weights to keep it from wobbling when we interacted with it.
The feedback that we got from judges was generally positive. People seemed to especally like the skull opening up to reveal the brein. Some negative feedback we got was to make the neck shorter.
