Ayunkowi Modificado

thingiverse

Firstly, thanks to Ayunken for the assistance provided in the initial days, the artist who modified the program and libraries so that the LED matrix functions is he, along with other things. He has reinforced the casings and legs of Ayunkowi to make them more durable. He strengthened the supports of the SG90 servos within the body because they easily broke. He made the legs shorter and stronger. He redesigned the head to fit in proximity sensor and keep it fixed, plus he added a support for the Bluetooth card and the button pad. On top of it, there are 4 supports for the Arduino shield. The head is higher than normal (7mm) so that two 18650 batteries can go on top of the servos without having to disassemble the robot when changing batteries. To charge it, a power bank board with a 5V 2A output is used; from the positive side it goes through the switch and then to any pin of 5V of the shield, while the negative side goes to any GND pin of the shield.
