Hybrid Exploration Robot for Air and Land Deployment
The H.E.R.A.L.D. system combines two different form factors: a quadrotor and a light-weight, nimble snake. The snake robot is designed to maneuver both over and through rubble, while the quadrotor provides aerial surveillance. The integration of these form factors, using two snake robots and one quadrotor, allows for increased maneuverability and operational lifetime.
Quadrotors have notoriously short battery life. The H.E.R.A.L.D. system allows for the quadrotor to be carried by two snakes while not in use, providing increased battery life without sacrificing mobility. In addition, snake robots alone are constrained to the ground. The H.E.R.A.L.D. quadrotor is capable of carrying a single snake, so that these robots may be transported to previously unreachable locations.
