Designed to operate in challenging terrain, RAVEN combines drone and robot capabilities, making it a game-changer for rescue, inspection and monitoring missions.
Imagine a robot that not only flies like a drone, but also walks, jumps and takes off without needing specific runways or surfaces. It sounds like something out of science fiction, right? But this is already a reality with RAVEN, a robotic bird inspired by the movements of birds, which promises to transform the future of technology. Developed by scientists, RAVEN was created to operate in challenging terrain, becoming an essential tool for rescue, inspection and monitoring missions.
What is RAVEN?
RAVEN — an acronym for “Bird-Inspired Robotic Vehicle for Multiple Environments” — is designed to mimic the movements of birds such as crows and jays, which are known for their ability to switch between walking and flying very efficiently. RAVEN’s biggest differentiator is its ability to take off in a single jump, a feature that makes it more agile and versatile than conventional drones.
Thanks to this design, the robotic bird saves energy during takeoff and quickly reaches an initial flight speed, making it easier to operate in difficult environments such as dense forests, mountains or disaster zones. This combination of abilities makes RAVEN a promising technology in several areas.

Why is RAVEN different from traditional drones?
Traditional drones are extremely useful, but they have limitations, especially in uneven terrain or hard-to-reach areas. They often require specific runways to take off from and lack the ability to navigate on the ground. That’s where RAVEN shines.
With specially designed legs, the robot can walk, jump over obstacles and even take off from difficult terrain. This nature-inspired design increases its efficiency and allows it to be used in missions where ordinary drones would not be able to operate.
For example, imagine a rescue team needing to reach a remote area after a landslide. While a traditional drone would struggle to operate in such an environment, the RAVEN robotic bird could easily walk through the rubble, take off in a single jump, and access areas that are otherwise off-limits to humans.
Robot Bird Applications
The possibilities for using RAVEN are endless. It was designed especially for missions in challenging locations, but its potential goes far beyond that. Among the main applications are:
- Rescue in disaster zones: The ability to walk and fly makes RAVEN ideal for accessing remote or devastated areas, such as landslides, earthquakes or floods, where it is difficult for humans or conventional drones to operate;
- Inspections in hard-to-reach places: The robotic bird can be used to inspect structures such as power towers, bridges or pipelines in mountainous regions;
- Package Delivery: In isolated locations where traditional vehicles and drones face logistical difficulties, RAVEN can ensure fast and safe deliveries;
- Environmental monitoring: With its ability to walk and fly, RAVEN can be used to study fragile ecosystems or monitor areas with difficult-to-access fauna and flora.
Challenges and next steps
While RAVEN has already demonstrated impressive capabilities, there are still challenges to overcome. One of the main ones is the lightweight structure. In order for it to fly and walk efficiently, scientists had to develop lightweight yet robust materials. Now, the focus is on improving the robot’s leg control and landing capabilities, ensuring greater precision and stability.
Researchers are also exploring new ways to apply this technology. In addition to rescue and inspection missions, there is growing interest in using RAVEN for interventions in disaster zones and even for commercial deliveries in remote areas.
Nature as technological inspiration
RAVEN's design is a clear example of how nature can inspire technological advancements. By studying the movements of birds, scientists have managed to create a robot with unique abilities, combining terrestrial locomotion with the ability to fly. This not only expands the possibilities of its use, but also represents a major advance in robotics.
Published in the prestigious scientific magazine Nature, the robot bird project is a milestone in the development of hybrid drones and robots. It paves the way for new solutions in sectors ranging from humanitarian relief to trade and environmental monitoring.
As technology advances, we’re likely to see robot birds become increasingly present in our lives, whether they’re helping with natural disasters, monitoring forests or ensuring deliveries to remote locations. For scientists, the challenge now is to make this technology even more efficient and accessible.
Whether soaring through the skies or trekking across challenging terrain, RAVEN proves that the future of drones isn’t just about flying — it’s about adapting to any environment.
