Read the following excerpt from "Fold Here: Scientific Uses for an Ancient Art Form." As you read, look for the topic sentence.

Question

One of the most exciting areas to explore the uses of origami today is robotics. Scientists at NASA's Jet Propulsion Laboratory in Pasadena, California, have created PUFFER, a "Pop-Up Flat Folding Explorer Robot" that can accompany rovers exploring other planets. According to a press release from the National Science Foundation, this light-weight, two-wheeled robot is "designed to skitter up 45-degree slopes, investigate overhangs and even drop into pits or craters." Because of PUFFER's compact nature, several separate units can piggyback on a single space rover.

What is the topic sentence for this paragraph?
