Robotics I Unit 2 Test Review

An analog sensor, such as the VEX IQ Optical or Distance Sensor, is a type of sensor that reports ________.

• A range of values

• Boolean values such as true or false/0 or 1

• Errors in a program

• Letter grades based on the quality of the sensor reading

Which of the following SSPA components means that a programmer should write a program that tells the robot what to do and how to react to the world around it?

• Sense

• Percieve

• Plan

• Act

Which sensor is best suited to dectect the amount of brightness of an object?

• Distance Sensor

• Optical Sensor

• Touch LED Sensor

• Both Optical and Distance Sensors

Which should be the first step when programming the robot to move until a certain brightness percentage?

• Run the program first, then make changes as needed

• Make sure the Distance Sensor is working correctly

• Test and take note of the Optical brightness values of the surface it will be driving on to come up with a threshold value

• All of the above

• The conditional will be true when the Optical Sensor detects an object or detects red

• The condition will be true when the Optical Sensor detects an object (only)

• The condition will be true when the Optical Sensor detects red (only)

• The condition will be true when the Optical Sensor detects an object and detects red

A "wait until" block ...

• Holds program flow in that place in a program

• Needs a true condition to proceed in program flow

• Helps a robot make a decision

• All of the above

How does the Touch LED sensor act as an output?

• It can detect touch

• It can produce sound

• It can display different colors

• It can detect amount of force

A digital sensor such as the Touch LED or Bumper Sensor is a type of sensor that reports...

• A range of values

• Boolean values such as true or false/0 or 1

• Letter grades based on the quality of the sensor reading

• Driving velocity

_________ is used to outline and plan a program before translating it into code.

• Sequences

• Digital Sensor readings

• Robot model

• Pseudocode

Which sensor is best used to detect obstacles?

• Touch LED Sensor

• Bumper Sensor
