Invisible Highway is an experiment that uses augmented reality to create tracks and scenery for a real robot! The makers of this project were able to utilize the contents from AdaBox 002: Making things Move!! Via Experiments with Google:
Invisible Highway is an experiment in controlling physical things in the real world by drawing in AR. Simply make a pathway along the floor on your phone and the robot car will follow that path on the actual floor in your room. A custom highway with scenery is generated along the path to make the robots a little more scenic on your phone screen.
Built by Anna Fusté Lleixà, Judith Amores Fernandez and Jam3 with friends at Google Creative Lab using Unity, Tango, and AdaBox maker kit from Adafruit.
