Last update: 24/11/2018. Fixed holes for DC motors on wheel_right and wheel_left parts. Fixed holes for Arduino Uno R3 and L298N H-bridge on base part.
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 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.
Special thanks to the other team members involved in the project:

How can you help? This project is funded by team members and small donations from some enterprises. If you liked it, there are some ways you can help us:
Donation: you can send us tips if you want to support the construction of the robot and its future improvements. The tips will be used to buy supplies (electronics, 3d printing, filaments, etc.) and to help the promotion of our interventions in children's hospitals. Your name will de added to the credits of the project!
Like: Show us how much you appreciate our project. Give us a "like" on the platforms we document our project (Facebook, Hackster, Hackaday, Maker Share, Thingiverse...).
Share: Share the project on your favorite social media website, so that we can reach more people, and inspire more makers around the world.
How I Designed This
The robot structure was entirely produced with 3D printing using Autodesk Fusion 360. In order to enable the production of robot replicas in makerspaces or fab labs, where the maximum time of use of the printers is crucial, the design of the robot was divided in pieces smaller than three hours of printing each. The set of parts is glued or bolted for body mounting. The model is composed of 36 different parts. Most of them was printed without supports, with 10% infill.
