Insect-Inspired Strategies for Safe Landing in Flapping-Wing Aerial Microrobots

Strategic Insights

— 1 min read

Researchers from Harvard University have made a groundbreaking discovery in the field of robotics, inspired by the landing behaviors of flying insects. The study, funded by the National Science Foundation, aimed to create a mechanical and control approach for achieving safe and accurate landings in flapping-wing microaerial vehicles. By analyzing the landing strategies of real insects, the team designed lossy compliant legs that can dissipate energy during surface collisions, similar to the crane fly's legs. They also developed a controlled landing sequence, mimicking the deceleration and impact velocity observed in insects.

Key Takeaways:

  • The researchers designed lossy compliant legs that can dissipate energy during surface collisions, inspired by the legs of the crane fly.
  • The controlled landing sequence includes an initial acceleration from hovering, followed by deceleration toward the target, ending with a nonzero impact velocity, similar to what is observed in insects.
  • The proposed approach combines mechanical and control mechanisms for achieving safe and accurate landings in flapping-wing aerial microrobots.
  • The researchers verified the controlled, safe, and accurate landing on natural terrain using an insect-scale flapping-wing aerial microrobot platform (Harvard RoboBee).
  • The study highlights the importance of understanding the landing behaviors of insects and adapting these strategies for the development of advanced robotics.
  • The researchers include Nak-seung P. Hyun, Christian M. Chan, and Alyssa M. Hernandez, among others, as co-authors of the study.
  • The study was peer-reviewed and published in Science Robotics.

Statistics:

  • The study was funded by the National Science Foundation (NSF).
  • The research was conducted at Harvard University, specifically in the John A Paulson School of Engineering and Applied Sciences.
  • The controlled landing sequence involves an initial acceleration of unknown magnitude, followed by a deceleration phase lasting approximately unknown duration.
  • The impact velocity for landing is similar to what is observed in insects, with a specific value of unknown magnitude.
  • The study used an insect-scale flapping-wing aerial microrobot platform (Harvard RoboBee) to verify the controlled, safe, and accurate landing on natural terrain.
