Joy Robot (Robô Da Alegria)

First Prize in the Instructables Wheels Contest, Second Prize in the Instructables Arduino Contest, and Runner up in the Design for Kids Challenge. Thanks to everyone who voted on us!!

Robots are getting everywhere. From industrial applications to underwater and space exploration. But my favorite ones are those used for fun and entertainement! In this project a DIY robot was designed to be used for entertainment in children's hospitals, bringing some fun to the kids. The project is focused in sharing knowledge and promoting technological innovation to assist NGOs that carry out charitable work in children's hospitals.

I this project a remotely operated humanoid robot was designed, controlled over a Wi-Fi network, using an Arduino Uno connected to an ESP8266 Wi-Fi module. It uses some servomotors form head amd arms movements, some DC motors for moving small distances, and a face made of LED matrices. The robot can be controlled from an ordinary internet browser, using a HTML designed interface. An Android smartphone is used to broadcast video and audio from the robot to operator's control interface.

The whole structure of the robot was 3D printed, and it uses open hardware and open software at its core.
