The Infineon crew’s XXL Chatbot gives you yuletide greetings

Infineon is without doubt one of the world’s largest semiconductor producers, however the firm is made up of normal folks like every other. Lots of these folks simply occur to be engineers they usually prefer to construct devices and gizmos like the remainder of us. Following a water cooler dialogue about who had the most important 3D printer, the Infineon crew determined to create this delightful XXL Chatbot to offer yuletide greetings.

The cute robotic was designed after the Infineon Chatbot avatar that provides digital help on the Infineon web site. Whereas that web Chatbot can reply to pure language questions, this XXL Chatbot can solely emote by its animated eyes and chest-mounted RGB LED matrix. The crew 3D-printed the robotic’s physique in a number of sections on a Creality Ender-5 Plus and the assembled determine is kind of massive, therefore the “XXL” designation.

They animated the eyes utilizing two customized PCBs, every of which has a diameter of 60mm and accommodates 101 SK6812MINI individually addressable RGB LEDs. They managed these with a pair of Infineon XMC2GO microcontroller improvement boards. The chest show is a versatile 64×32 RGB LED matrix from Adafruit, which conforms to the cylindrical curve of the robotic’s torso. They managed that LED matrix with an Arduino Mega 2560 board by Adafruit’s RGB Matrix Defend. It shows a Christmas tree animation derived from z1co’s animation set for 32×32 matrices.

The result’s a cheerful and cute robotic that matches completely with the vacation season!
