Science Now ep. 9

The video discusses various NSF-funded research projects. It covers the Yeti robot, which uses radar to detect ice crevasses, enhancing safety and advancing robotic learning. The GRACE robot combines swimming and gliding to navigate water bodies efficiently, aiding environmental research. An experimental electric car with independent wheel control promises improved traction and energy efficiency. Lastly, song sparrows use song matching as a territorial signal, providing insights into communication systems.

What is the primary function of the Yeti robot?

• To transport equipment across ice

• To provide weather data

• To map under-ice hazards using radar

• To measure ice thickness

How does the GRACE robot improve its navigation efficiency?

• By using solar power

• By combining swimming and gliding movements

• By following pre-set paths

• By using a human operator

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

• It can fly short distances

• It is powered by wind energy

• It has independently turning wheels

• It uses a diesel engine

What behavior do song sparrows exhibit to protect their territory?

• They build larger nests

• They sing louder than usual

• They match the intruder's song

• They fly in circles

What is the main challenge in developing the new electric car's traction system?

• Increasing its speed

• Reducing its weight

• Making it affordable

• Ensuring it is energy efficient and safe
