I2C update

Finally got the I2c bus to work I had to disable the internal pull up resistors add external resistors
and make a PCB to act as a hub every thing was working then a few days later it stopped working
I traced this problem to the powered USB hub, I added a camera then everything started to go weird programmers not responding, garbage on the I2C and the arm going off the stops. I supplied 9Volts to the MCU's and everything started working as normal.(I just wish it was that simple it took me 3 days to figure it out)

I added a camera to Robbie's left eye its a stripped down logitech that's been hot glued in place it works well now when I find some free time I just need to get the head tracking working again

I sanded painted the head a mat white the parts looked really good then I left them outside to dry
BAD move the PLA warped due to the heat and I had to reprint the top part of the head. I glued the top together so it looks better from the front I'll repaint it at a later date

Robbie gets a head 2

Inmoov gave us all a Easter present normally it a chocolate egg but this year its a plastic head I think it really make Robbie look good. Now to dust off the head tracking, face recognition and the AI program he needs to speak.

we still have to do s bit more finishing and painting and find the right cameras for the eyes
