Raspberry Pi Rescue Robot

The Scouting Owl Project A rescue robot can play an important role in searching for endangered individuals and studying hazardous conditions. Learn how these Cornell students built a Raspberry Pi 4-based robot that allows rescuers to detect and communicate with endangered individuals in an environment that is not yet suitable for in-person rescue.

For increased safety of first responders, an autonomous robot that can detect endangered individuals, avoid obstacles, scout the environment and communicate with endangered individuals in extreme environments would be a desirable safety improvement. SYSTEM OVERVIEW Scouting Owl is a robot that allows the rescuers to detect and communicate with endangered individuals in an environment that is not yet suitable for in-person rescue. To perform the critical rescue task, we built a robot based on a Raspberry Pi 4, with the following functions: 1) a reliable half-duplex connection between the robot and the control device; 2) fetching and displaying live IR camera feed along with sensor data on the display device; 3) remote control of the robot through an Android App; and 4) mapping the surrounding area (Figure 1).
