A four-wheel vehicle for detecting deadly cracks in Antarctic ice!

The video discusses various NSF-funded research projects. It starts with the Yeti robot, which uses radar to map ice crevasses, enhancing safety and advancing robotic learning. Next, it covers GRACE, a gliding robot that autonomously navigates water bodies, aiding environmental research. The video then introduces an innovative electric car with independent wheel control, promising improved traction and energy efficiency. Finally, it explores song sparrows' territorial behavior, revealing how they use song matching as a communication tool.

What is the primary function of the Yeti robot in Arctic and Antarctic regions?

• To provide communication signals

• To transport equipment across ice

• To map hidden crevasses using radar

• To measure temperature changes

Which feature allows GRACE to navigate efficiently in various water bodies?

• Its advanced sonar system

• Its ability to combine swimming and gliding movements

• Its lightweight design

• Its solar-powered battery

What is a unique feature of the experimental electric car developed by Ohio State University?

• It can fly short distances

• It has a solar charging system

• Its wheels turn independently for better control

• It uses hydrogen fuel cells

How do song sparrows initially respond to an intruder in their territory?

• By attacking immediately

• By matching the intruder's song

• By flying away

• By building a new nest

What is the main goal of the song sparrows' signaling behavior?

• To avoid a fight

• To find food

• To migrate to a new area

• To attract a mate
