Robotics Chapter 3 Quiz

What is an algorithm?

• A sensor that detects sounds.

• A set of instructions, such as a computer program, written to make a robot or computer do what you want it to do.

• A program that when run asks the user for his/her name before doing anything.

• A type of robot wheel that runs smoothly over rough terrain.

Sensors allow a robot to not only sense and/or measure something in its environment, such as object detection, sound or temperature, but it allows the robot to _________________the environment as well as well.

• freak out from

• control

• see input as bogus and reject

• react to

An algorithm can make a robot do what? (Check all that apply.)

• turn left

• play a sound

• drive faster than a motor can actually perform.

• stop

When something occurs, such as an object is detected, that is called an ____________ and the part of the program that reacts to it called an _________________.

• occurrence, reaction algorithm

• event, event handler

• happening, reactionary process

• sensor, robot brain

When a robot has 2 motors, what happens if the left motor moves forwards, and the right one does not?

• The robot moves backwards.

• The robot plays a sound

• The robot turns left

• The robot turns right.

What does a robot do if both motors are moving forward at at 50%?

• The robot moves forward at half of its maximum speed.

• The robot experiences an error and the motors beep.

• The robot stops.

• The robot moves forward 50x faster than its maximum speed.

An algorithm to make a robot not only stop when it detects an object, but to move away from it would include what line of code?

• If the object moves away from the robot, the robot will turn left and beep.

• If the object is less than x feet from the robot, the robot will move backward until it is x feet away from the object.

• If the robot touches the object, it will turn around and go forward until the operator pressed the stop button.

• If the robot's battery is dead, the robot will spin in circles until someone kicks it.

If an algorithm doesn't include a way to back up, what program can happen?

• The robot's battery won't last long.

• There is no way to race in reverse!

• If the robot hits something, it could be stuck.

• If the robot hits something, the tire will pop.

What do we use when we want a robot to do something if something happens.
