Introduction

FloatForm is a swarm of small autonomous robotic boats that can assemble, separate, and reconfigure into floating infrastructure. The project connects robotics, distributed control, urban planning, and bio-inspired engineering.

Vocabulary

swarm — a coordinated group; reconfigurable — able to change arrangement; autonomous — operating without continuous human control; assemble — join into a larger structure; infrastructure — basic systems and facilities; underutilized — not fully used; resilient — able to recover from disruption; decentralized — controlled without a single central authority; intervention — action taken to change a situation; scalable — able to grow without breaking down; trajectory — path of motion; disturbance — external disruption; robust — reliable under imperfect conditions; deploy — put into practical use.

Reading comprehension

1. What is FloatForm?

Reference answer
It is a system of small self-contained robotic boats that autonomously assemble into larger reconfigurable floating structures.

2. Why did researchers take inspiration from fire ants?

Reference answer
Fire ants demonstrate how simple individuals using local behavior can collectively form useful structures such as rafts.

3. What weakness does centralized control create in a robot swarm?

Reference answer
A central controller can become a bottleneck or single point of failure and must handle increasing communication and computation as the swarm grows.

4. Why is decentralized coordination more scalable?

Reference answer
Each robot can make decisions using local information, so adding more robots does not require one controller to manage every interaction.
