Story

It all started with a song.
Legend has it, when David Bowie was briefly living in Los Angeles, his good friend Iggy Pop was visiting him, complete with a skull full of hallucinogens. At the time, He apparently thought his girlfriend was being eaten by Bowie's new television. What songwriter worth their salt could pass up immortalizing this story? Not Bowie.And with that TVC15 became one of my favorite songs on one of my favorite albums, Station to Station.
My robot, the TVC15 is my personal homage to the song and the songwriter. It's also my introduction to interactive robotics.
The majority of his parts are 3D printed and designed in Autodesk Inventor. The TVC15 uses an Arduino mega for the brain. His face is 16x32 pixel LED matrix. Each arm has 3 servos, and the neck has 2, devoted to pan and tilt movement. Attached to the head is a 4 IR sensor array that feeds input to the Arduino.The Arduino takes the data and moves the neck servos accordingly. This is updated continuously. A "ping" sonar sensor determines if someone is approaching.If the sensor is tripped, the TVC15 will go through a routine where the led matrix run a sequence of animated lights.After the display, each hand will raise and wave to the spectator.
Future improvements: The LED matrix and servos tend to draw a lot of current.Batteries cannot hold a charge for long, and as a result, the robot is currently stationary, powered by a 5 volt 10 amp power supply. I would eventually like to move it to a mobile platform, and I am investigating the options available. For the time being, he's okay hanging out where he is.
