02 Robot Bodies

According to the text, what is the main difference between analysis and synthesis in robotics?

• Analysis is about building, while synthesis is about destroying.

• Analysis is about taking things apart, while synthesis is about putting things together.

• Analysis is only used by engineers, while synthesis is only used by scientists.

• Analysis and synthesis are the same process.

Why are both analysis and synthesis important in robotics, as described in the text?

• Because only scientists need to understand robots.

• Because robotics only requires building new devices.

• Because they are complementary ways to figure out how something works.

• Because engineers do not need scientists' understanding.

Where is the controller of Roomba located?

• On the motherboard

• In the battery compartment

• Inside the dustbin

• On the chassis

Which component of Roomba is responsible for linking and coordinating the functions of sensors and actuators?

• Controller

• Chassis

• Battery

• Dustbin

Why is the home base considered part of Roomba’s energy supply chain, even though it is not part of the robot itself?

• Because it recharges the battery

• Because it stores dust

• Because it controls the actuators

• Because it filters air

Which of the following is NOT considered a part of Roomba’s body?

• Controller

• Dustbin

• Filter

• Top cover

Explain how the actuators in Roomba are categorized and describe their roles in the cleaning process.

• They are categorized into those that move Roomba and those that spin brushes or fans to move dirt.

• They are categorized into sensors and controllers.

• They are categorized into batteries and filters.

• They are categorized into dustbins and covers.

According to the text, what happens when a human remotely controls a robot?

• The robot becomes more autonomous

• The robot's sensors stop working

• The robot is no longer autonomous

• The robot's energy supply increases

Which of the following is an example of a trade-off in the design of the Roomba robot?

• It can climb stairs but not clean floors

• It can clean floors but not climb stairs

• It can fly but not move on the ground

• It can cook food but not clean floors

Why do many robots have a built-in ability to be both autonomous and remotely controlled?

• To save energy

• To allow humans to enter the control loop when necessary

• To reduce the number of sensors needed

• To make the robot heavier
