The video discusses the evolution of machines and their noise impact on the environment. It introduces biomimetic machines made from soft materials, highlighting the development of a robotic fish named Sophie. The video explores challenges in creating silent robotic muscles and emphasizes design optimization. It envisions a future with living robots that can self-heal, promoting sustainability and reduced pollution.

What is one of the main issues caused by traditional motors according to the video?

• They are too expensive to produce.

• They cause environmental noise pollution.

• They are not energy efficient.

• They are difficult to repair.

What is the primary function of Sophie, the robotic fish?

• To clean the ocean floor.

• To explore aquatic life without propellers.

• To transport goods underwater.

• To monitor water pollution levels.

What is the main limitation of Sophie as mentioned in the video?

• It is energy hungry and loud.

• It cannot be controlled remotely.

• It is too expensive to produce.

• It cannot swim in deep waters.

What are hazels in the context of the video?
