Biomimetic Machines and Robotic Fish

The video discusses the evolution of motors and their environmental impact, proposing biomimetic machines as a solution. It introduces Sophie, a robotic fish developed by MIT and ETH Zurich, which mimics natural swimming. The video explains the use of HASELs, artificial muscles that convert electrical energy into movement, and highlights the potential of living muscle cells in future robotics. The focus is on creating sustainable, biodegradable machines that integrate with nature.

What is a major drawback of modern rotating motors according to the video?

• They are difficult to maintain.

• They are not powerful enough.

• They are loud and unnatural.

• They are too expensive to produce.

What is the main advantage of biomimetic machines over traditional machines?

• They are cheaper to manufacture.

• They can operate in space.

• They mimic natural movements.

• They require no energy to operate.

What is the name of the biomimetic robotic fish developed by the researchers?
