Abstract

The Tetrix Urban Search and Rescue (S&R) robot is a mobile robot equipped with a vision system and a real-time image processing engine. Both the vision system and processor can be accessed through a wireless connection. This allows users to navigate the robot through unknown terrain using streaming video from the vision system to do image mapping and obstacle avoidance. An instructional module for high school students was created based on this robot. Students planned, reconfigured, and controlled a Tetrix Robot for a given search-and-rescue scenario. During lectures, the instructor demonstrated how to control the robot using various approaches such as a remote panel or a computer. Students then familiarized themselves with a pre-built Tetrix demo robot structure, control system, and sensors, focusing particularly on the vision sub system. A special activity (“Ranger, Help”) was conducted. The class was divided into three-person teams. Each team selected a Control Operator (CO), Data Specialist (DS), and Field Technician (FT). The CO controlled the Ranger Robots' movements through all simulations. The team simulated a search for survivors in a town ravaged by two tornados. The DS and the CO watch a monitor to analyze and document what the Ranger finds. The team understands their first priority is to locate survivors and communicate their location to the FT so they can go in and get them. Any non-surviving locals are documented so that recovery teams will be able to come back in to get them. The FT informs and coordinates the lifesaving efforts of the field teams. Once the FT starts a site team, they move on to the next local reported by the DS. Through teamwork, students learned how vision systems work, how to process images for meaningful knowledge, and how to work as a team to achieve a S&R task using a robot platform. Evaluation results suggested students were very motivated in the activity. Learning of image processing tasks was moderate, but they were proficient in controlling a S&R robot for a given task
