Biomimicry: Echolocation in Robotics

Students use ultrasonic sensors and LEGO© MINDSTORMS© NXT robots to emulate how bats use echolocation to detect obstacles. They measure the robot's reaction times as it senses objects at two distances and with different sensor threshold values, and again after making adjustments to optimize its effectiveness. Like engineers, they gather and graph data to analyze a given design (from the tutorial) and make modifications to the sensor placement and/or threshold values in order to improve the robot's performance (iterative design). Students see how problem solving with biomimicry design is directly related to understanding and making observations of nature. Less

Students' understanding of how robotic ultrasonic sensors work is reinforced in a design challenge involving LEGO® MINDSTORMS® NXT robots and ultrasonic sensors. Student groups program their robots to move freely without bumping into obstacles (toy LEGO people). They practice and learn programming skills and logic design in parallel. They see how robots take input from ultrasonic sensors and use it to make decisions to move, resulting in behavior similar to the human sense of sight but through the use of sound sensors, more like echolocation. Students design-test-redesign-retest to achieve successful programs. A PowerPoint® presentation and pre/post quizzes are provided. Less

Students model and design the sound environment for a room. They analyze the sound performance of different materials that symbolize wallpaper, thick curtains, and sound-absorbing panels. Referring to the results of this analysis, they then design another room based on certain specifications and test their design. Less

Glen Echo Park: Center for Education and Recreation

Traces the evolution of this Maryland site from a chapter of the Chautaqua movement, to an amusement park, to a national park. This spectacular Maryland location, so lovingly described by Edward and Edwin Baltzley, its first developers, has served the people of Washington, D.C., as a center for education and recreation for more than 100 years. It was first developed as a chapter of the widespread Chautauqua movement–a Protestant ecumenical effort to democratize learning and spread culture from the well-to-do to the masses. Early in the 20th century the area was redeveloped as a trolley park, and now the site is preserved as a national park. The trends that impacted the development and redevelopment of the Glen Echo Park site are not unusual; the fact that they impacted the same area of space is. This unique survivor, a traditional gathering place for the people of Washington, D.C., provides students with the opportunity to study the evolution of the American concepts of education, recreation, and social interaction in the late 19th and 20th centuries. Lesson plan included. Less

Students learn about how ultrasonic sensors work, reinforcing the connection between this sensor and how humans, bats and dolphins estimate distance. They learn the echolocation process—sound waves transmitted, bounced back and received, with the time difference used to calculate the distance of objects. Two mini-activities, which use LEGO® MINDSTORMS® NXT robots and ultrasonic sensors, give students a chance to experiment with ultrasonic sensors in preparation for the associated activity. A PowerPoint® presentation explains stimulus-to-response pathways, sensor fundamentals, and details about the LEGO ultrasonic sensor. Pre/post quizzes are provided. This lesson and its associated activity enable students to gain a deeper understanding of how robots can take sensor input and use it to make decisions via programming. Less
