A hybrid air-ground vehicle design that cycles through a regenerative energy phase during a ground-based trajectory. The regenerative ground-based trajectory, in turn, produces energy for purposes of implementing another air-based trajectory cycle. The design significantly improves the versatility and endurance of robotic position-adaptive sensor designs. The radar (or electro-optic) sensors on the platform perform surveillance operations during both the ground and air trajectories of the hybrid air/ground vehicle.
