Hello Rongzhong, thanks for your reply. This is how the Bittle arrived to me, can you tell me if there is something wrong in how it was assembled?

thank you! This is how I got it since it came assembled already. I don't necessarily want a replacement if it is something I can change and learn. I was looking at another post for Nybble and it looked interesting, so I was wondering about specificatilns for servos, maybe I can buy other kinds? Or are these servos specifically designed for Bittle?

Thank you. Everything is so new. I got scared because the limbs move so fast sometimes and they vibrate and sometimes go into weird positions and I freak out thinking something will break haha. I tried codecraft to understand a little bit more. Does uploading a sketch erase the main functionality? I mean, does uploading the testBuzzer remove the instincts?

Very useful. I speak spanish so it is easier to understand :) Grazie!
