I created this design for my sister, I had the Pololu Round Robot Chassis Kit so I created all the parts according to it. I created different versions of stl files, some have holes for sensors, it depends by what you want to create. I ordered ultrasonic sensor to avoid impacts, bluetooth module to control R2D2 with my smartphone. (Online there are many apps, I have still to decide which one I can use). The head has a hole for the led. The base has a hole for an on/off switch. I ordered a servo to move the head (but I have to test it, probably servo isn't enough) I will use a module and a speaker to make it talk. Most of modules are in travel to my house so I will keep updating this post. If you have any sugguestions or questions feel free to write me. :)P.s.I used adhesive paper to finish the details of R2D2 so I added the stencils to make some details.#update 03/03/16I added the arduino code and the schematics for a stand-alone r2d2 (bluetooth version is coming)https://youtu.be/aKiF9KvHPuA#update 12/03/16ok a new video, and a controlled R2D2 , probably more beautiful than beforenew code and new schematicshttps://www.youtube.com/watch?v=Hq7MXziumRo#last updatehttps://www.youtube.com/watch?v=eSDkyJnjunoApp for Android https://play.google.com/store/apps/details?id=com.heightdev.arduinobtjoysticklite&referrer=utm_s...
