If you need a 15 min time filler in robotics class this is a great worksheet. It has links to 6 robotics videos and reflections for each. You could do the entire worksheet in a 90 min sitting. However I think it's best used as a quick time filler of 15 min. Or watch a few on a day you have to have a sub. Keep the worksheet then hand out again to work on the next video when the time is right. Videos are about the variety of robotics applications in present time and the future.
