OK, thanks. I checked my parts and found the bluetooth dongle, so I guess it will work. I was concerned that since this one an early release, it may not contain all the same parts as a current release.

Great! Thank you for the response - I just filled in the survey 😉

Again - thanks for your time !

FYI - Here's a video after assembly - starting position 'd', then 'kbalance', then 'd' again: Also - How do I test the Ultrasound sensor and the RGB LED ?

Ok, I'll assemble it and try it. I'll re-post here if it doesn't work. Thanks again.

"Pushed flat" (by hand?)! I thought the 'd' rest state was supposed to fold down that far via the servos! Based on that, I don't think anything is wrong... D'oh!

I'm expecting the knee joint to 'close down' nearly 90 degrees from the 'c' state as shown in the manual but they only reach about 45degrees from 'c':

No - exactly the same. "d" only moves them about 45 degrees, not the almost 90 shown in the pictures.

OK, Done!

Yes (the knee rotated towards the rear)

Same as before...No change

I've turned the board over and reconnected everything. I've also run Nybble.ino and tested each joint to make sure they're correct i.e. "m13 10" to move the right front knee 10 degrees. Sorry - I'm not really seeing how to make the change. I apologize for being so difficult...

Thanks for looking into this :) (I"m pretty sure I've got the board upside down for mounting, so I must also have Left/Right swapped)

Wait! It's working now - I think the Baud rate/newline setting was wrong. I reset to No line ending and 57600 and it's working!

Wow - that was fast! I see it now - the screw holds the servo arm in place along with the rivet for additional movement. It looks like the screw was never supposed to attach to the shoulder. Thanks! (FYI - I haven't finished with Nybble yet, but I already supported Bittle too!)

Are you able to send a photo or illustration of the tail affixed to the shoulder without the screw?

Rongzhong - Thank you for replying to my post - your answers are very helpful. However, I still don't understand how to attach the tail if there is no screw hole in the rear shoulder. I must be misunderstanding something...can you explain? Regarding parts like the rubber toe, etc. - will there be a way to purchase spare parts? For example, in my kit one of the Y1 parts snapped in two. I was able to glue it back together, but I suspect in some cases this may not be possible... Again, thanks!
