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.
Three source-described robot phases and one fixed brief
Read the explanation
Swim, Surface and Fly are three manually selected descriptions. Each button replaces one panel title and paragraph and marks exactly one active phase. At one hundred fifty pixels per item, the bars compare three available phase choices with one active choice. The display describes a supplied post, not a robot simulation. No motion, propulsion, launch speed, control or performance is calculated. The supplied sequence is swim underwater, burst through the surface, then fly away. Three ordered entries have two adjacent transitions: swim to surface and surface to fly. Bars compare three entries with two transitions at one hundred fifty pixels per count. These counts describe the source sequence only. The post attributes the robot to EPFL and MIT, says under three hundred grams and mentions swappable wing sizes. It supplies no measured mass, wing dimensions, depth, speed, endurance or timing. Changing any of the three phases stores the selected key locally, and reload restores its description. Download always produces the same robot brief: mission, constraints and source boundary. It is independent of the selected phase. Bars compare three possible stored phase keys with one fixed export document at one hundred fifty pixels per item. This saves a reading aid; it neither controls hardware nor verifies the source robotics claim. The page has no reset control.
