THE SEQUENCE
Swim. Burst. Fly.
EPFL and Massachusetts Institute of Technology are credited in the supplied post with building a flapping-wing robot that connects all three phases.
Bio-inspired mobility
One body. Three environments.
The supplied post describes a flapping-wing robot that follows a diving bird's sequence: swim underwater, burst through the surface, then fly away.
<300g
Under 300 grams, with wings that swap out for different sizes. The post gives the constraint and the modular idea, not performance metrics.
Movement is the interface.
Read the robot as a transition problem: underwater propulsion, a surface breach, then aerial flight in one compact platform.
THE CONSTRAINT
Under 300 grams.
Low mass is the headline engineering boundary visible in the source.
THE ADAPTER
Wings that swap.
Different wing sizes are described as interchangeable, making the body adaptable without adding unsupported use cases.
Trace the mission
Choose a phase.
Underwater first.
The robot begins in the water, matching the first part of the diving-bird behavior described in the post.
