The Engineering Ambassadors will present on the applications of digital lighting; Light Emitting Diodes (LEDs) for a multitude of applications beyond lighting. This includes communications and large scale applications of LED lighting systems. Students will be exposed to technological advances that they probably never imagined and how crucial they are to the electronic devices they enjoy in today’s world. The presentation is suited for but not limited to general middle school class, technology and physics (core, regents and AP) classes.
The presentation begins with examples and definitions of a robot, algorithm, and path finding. Then we start a small discussion on the applications of mathematics in robotics by providing examples of both simple and complex applications. We break mid-presentation for the hands on activity. The hands on activity mostly involves the simple equation: circumference * # of rotations = distance traveled. The end goal of the activity is to have the kids program a small NXT robot to move and pick up a ball without using trial and error. We give them a handout that has the recommended paths and distances the robot should cover as well as information on the dimensions of the robot so they can make the calculations. After the hands on activity we close the presentation with a short discussion on modeling the behavior of some small single celled organisms (E-coli) with mathematical algorithms as well as the future of path finding robotics (like autonomous cars).
People rely on the engineering behind the science of sound everyday, whether its through listening to an Ipod, setting up speakers for a public event, or even through hearing aids. And yet, in this digital age, it is not clear to many people how exactly sound is stored in a digital device, what sound actually is, and how sound can be produced electronically. Therefore, this presentation displays and explains the intriguing engineering behind sound and its application in electronic devices.
