Story

Merry Christmas everyone!!!!

This Christmas we went for a scaled up version of our 3D printed "Greeting Chatbot". This time with animated eyes and curved display on its belly.

1 / 2 • Infineon XXL Chatbot - Christmas style

You know these afternoon coffee discussions about 3D printing, right? We got to the question "who in the team has the biggest printer?" and we ended the ranking with a Ender 5 Plus with a massive build volume of 350 x 350 x 400 mm. That said we scaled our Chatbot up to the max and ended up with these beautiful 3D printed parts:

Printed Chatbot parts, lower parts already glued together

If you have ever chatted with our Chatbot at www.Infineon.com you might have recognized the different emotions reflected on its eyes and the curved belly screen capable of displaying information. To enable interaction with our XXL Chatbot we decided to build these features in reality.

The Eyes

To create a realistic look while being flexible with the Chatbot's expressions we created a round custom PCB, placing 101 SK6812MINI RGB LEDs in a circular pattern. The PCB shows a diameter of 60mm, production files can be found below.

You control the SK6812MINI similar to the famous WS2812. Using a single data line you can daisy chain as many LEDs as you like and use the standard known Neopixel libraries available. Thanks to ederjc we also got an eye library based on Adafruits Neopixel library showing a few view expressions and animations using these PCBs. Here you can see our setup chaining two eyes. They are driven via a small XMC2Go microcontroller board.

The Curved Belly Display

Our second display needed to be flexible so we can fit it into the round body of our Chatbot. Adafruit offers a 64x32 Flexible RGB LED Matrix which is a great solution for this. We 3D printed two pieces to bend the PCB in place.

And glued it into the chatbot body

1 / 2

This display is driven by an Arduino Mega and a display shield provided by Adafruit. Check their guide as the shield has to be customized to work in this setup.

1 / 2

z1c0 created some awesome animations for the 32x32 pixel version of the display. We slightly modified the Christmas tree to work with our bigger matrix and scaled it down to fit perfectly.
