The Robot Challenge: Design and Problem Solving

The video tutorial presents a challenge of retrieving a phone from a sewer using engineering principles. It explains the engineering process, including defining the problem, brainstorming solutions, and designing a robot. The tutorial emphasizes testing and adjusting variables to ensure success. It concludes by encouraging viewers to design their own solutions.

What problem does the narrator need help solving?

• Crossing a dangerous canyon

• Designing a new phone

• Fixing a broken phone

• Retrieving a phone from a storm drain

What is the first step in the engineering process?

• Defining the problem

• Testing the solution

• Building a prototype

• Brainstorming solutions

Which of the following is NOT a potential solution considered by the narrator?

• Building a robot

• Using a magnet

• Lowering himself with a rope

• Using a fishing pole

Why does the narrator reject the idea of using a fishing pole?

• He can't see where he's aiming

• The phone is too heavy

• He doesn't have a fishing pole

• The pole is too short

What feature does the narrator decide the robot must have?

• A drill

• A water pump

• A suction cup

• A flashlight

What is a fixed variable in the narrator's mission?

• The size of the propellers

• The depth of the sewer drain

• The material of the robot

• The type of camera

What should be done if the robot can't lift the phone?

• Make the propellers bigger

• Use a stronger suction cup

• Reduce the weight of the phone

• Shorten the depth of the drain

What is the purpose of isolating variables during testing?

• To save time

• To ensure the robot is waterproof

• To make the robot lighter

• To see which variables affect performance

What is the final step before retrieving the phone?

• Testing the robot

• Building the robot

• Defining the problem

• Brainstorming solutions

What challenge does the narrator give to the students?

• To come up with their own solution

• To design a new type of phone

• To build a robot that can fly

• To retrieve another phone
