MIT's Insect-Sized Robot Redefines Terrain Navigation with Energy-Efficient Hopping

The thumb-sized robot combines a springy leg and flapping wings to traverse challenging terrains, carry heavy payloads, and pave the way for real-world applications.

Overview

  • The robot uses a spring-driven leg and four flapping wings to jump up to 20 cm, traverse uneven terrains, and maintain stability mid-air.
  • It consumes 60% less energy compared to similar-sized flying robots, enabling greater operational efficiency and endurance.
  • Weighing less than a paperclip, the robot can carry payloads up to 10 times its weight, making it suitable for tasks requiring additional sensors or circuits.
  • Advanced control systems and external motion-tracking ensure precise landing and orientation, even on dynamically tilting surfaces.
  • Future developments aim to integrate autonomous capabilities, enhancing its potential for disaster response and other confined-space applications.
