Part 4 - Program Control

What is robot?

• a programmable mechanical device that can perform tasks

• allows the machine to perform tasks without human guidance

• the science behind the design, building and use of robots

A program is:

• A logical step-by-step set directions for the robot to follow

• A set of directions, in paragraph form, that a robot can follow

• A logical set of directions for the programmer to follow

• None of the above

Which of the following is the definition of a FLOWCHART?

• a step-by-step procedure for solving a problem or accomplishing some end, especially by a computer

• a diagram that shows step-by-step progress through a procedure using connecting lines and a set of conventional symbols

• the return to the input of a part of the output of a machine, system, or process

• the place at which independent and often unrelated systems meet and act on or communicate with each other

An IF statement is triggered by....

• a condition

• a loop

• a comment

• a timer

The “while” command:

• Are commands that allow you to create behaviors where the robot acts until a certain event

• Are commands that waits for an elapsed amount of time in seconds or milliseconds

• Allows a section of code to be repeated as long as a certain condition remains true

• Is not a command option in ROBOTC

The “until” command:

• Commands that allow you to create behaviors where the robot acts until a certain event

• Commands that waits for an elapsed amount of time in seconds or milliseconds

• Allows a section of code to be repeated as long as a certain condition remains true

• is not a command option in ROBOTC

An example of a scenario in which you might want to use an “if” statement is

• when programming an automatic light to turn on when it gets dark outside

• when programming a motor to run when using a switch

• when programming a robot to detect when a object is more the 25 cm away

• all of the above
