@CHAZ BRGR Sorry I don’t know what you mean. All I did was download it, unzipped it and installed it using the wizard. After that it was good and ready to go. Send screen shots maybe?

It's possible that you do not have the FTDI driver installed on your computer yet. Google it and install it, and try it again.

@Rongzhong Li Hi, are there any updates to the solution?

@Ravid Maduni ????? Nybble Kit does not include a pi. It includes the laser cut out of nybble along with all the servos, screws, etc. and the Ny board, which is his custom pcb. The ny board is separate from the pi, but you can use both the ny board and pi at the same time or use only ny board. The Nybble will still be functional and can do tricks/learn them without the pi. Pi is if you want to do more advanced stuff.

You can just buy the Nybble Kit. You don't need any of the capacitors or resistors, as the kit comes with everything you need (except for batteries and charger). You can follow the instructions for building the nybble with a raspberry pi, which is included in the guide.

Hi @Rongzhong Li! I have encountered another problem which can be seen here: https://imgur.com/a/4Icz3dE Basically what is happening is that the back left toe servo seems to be 'lagging' behind the others. In addition, do you have the stl file for the 'mid' piece of nybble's head? The bottom segment next to the screw hole on it is cracked and so is a portion parallel to it at the top, and I'm worried it could break.

Thank you, I used Freenove 14500 3.7v 800mAh batteries from amazon that I bought here https://www.amazon.com/Freenove-Rechargeable-Battery-Pointed-Protective/dp/B07Y4L572B/ref=sr_1_1?keywords=freenove+14500+battery&qid=1577161232&sr=8-1

@Liubomyr Thanks for advice, I had a dumb mistake and plugged in all servos backwards. Thanks for your help

Thank you! Dumb mistake on my end. I have everything calibrated and working perfectly now. Thanks so much for your help!

https://imgur.com/gallery/2DU32RD here are some pics and video. I apologize for delayed response. If you need anything else please let me know

Yes, I have that part solved now. The calibration table now shows. However, the servos don't move at all when I enter 'c'. Is it due to batteries? I have 14500 size 3.7v li-on batteries 800mah

It is going well, I have been able to get the frame properly together. However, when I upload WriteInstinct.ino and run it and get to the stage just before entering 'c' into the serial monitor to start calibration, nothing happens. There is no table for calibration and the cat does not move.

I have, but my problem is the belly piece not fully being inserted into the holes on the bottom, causing it to jut out on the back. The extra length on the back don't allow the Y piece to fully insert into the straight holes on the back piece, and therefore I cannot fully push in the servos on both front and back shoulders. We can also see in the video that all servos are fully pushed in, and mine cannot.

Is this how your back looks like?
