Roach Biobots: Toward Reliability and Optimization of Control

Imagine a natural disaster, such as an earthquake, causing residential buildings to collapse and trapping the people inside underneath the rubble. Over the following days, first responders spend a significant amount of time locating survivors. Despite having the assistance of life-detection tools and techniques, these first responders are still hampered by certain limitations in searching for survivors and pinpointing their exact location deep within the rubble. Current methods involving dogs and relatively large robots and machinery can assist only with surface-level surveying of the disaster area and removal of rubble. In contrast, a swarm of centimeter-scale robots could be employed for under-rubble mapping and surveying in these scenarios. In fact, progress has been made in developing centimeter-scale robotics that could assist first responders in the future. However, these prototypes still require improvements in the efficiency of the mechanical parts and control systems deployed in real-life scenarios.
