The document discusses 5 innovations that will impact the world: 3D printing, robotics, sensor-based homes (smart homes), autonomous vehicles, and drones. 3D printing allows complex objects to be replicated using printing technology. Robotics ranges from small programmable devices to large mobile units. Sensor-based homes use technology to monitor the home's condition. Autonomous vehicles can drive without human assistance. Drones are unmanned aerial vehicles used for tasks like targeting and reconnaissance.
