The three group members agree to create a flow chart so that all group members understand the plan and can work on the code.
5.
Which of the following is an example of a scenario where a robot will move autonomously?
a)
A coding software program is used to create code and is downloaded to the robot, so that the robot moves based on the code.
b)
A coding software program is used to create code, and a person pushes the robot with their hands so that it moves faster.
c)
A coding software program is used to create code but is not downloaded to the robot.

6.
Sophia and Jin are attempting to create an algorithm to make their robot do a shuffle with the following requirements: 1. It must last more than 20 seconds. 2. It must go both forward and backwards. 3. The algorithm begins when BumperA is pressed. Which of the following must be true of the algorithm?
a)
The event handler block must include “When Brain left button is pressed”.
b)
The “wait time” of all the actions must add up to 15 seconds.
c)
The event handler must include a loop.
d)
The event handler block must include “When BumperA is pressed”.
7.

a)
The arrows show the flow of the action.
b)
A command is represented by a rectangle.
c)
The beginning point is shown by a rectangle.
d)
The ending point is shown by a triangle.
8.
What is the difference between a repeat loop and a forever loop?
a)
A forever loop repeats steps for a set number of times, whereas a repeat loop repeats steps until the program stops running.
b)
A repeat loop is used to copy and paste the same set of code, in order, and a forever loop is used if you want to copy and paste the same set of code in reverse order.
c)
A repeat loop repeats for a designated number of times, whereas a forever loop repeats until the program stops running.
d)
A forever loop is used to copy and paste the same set of code, in order, and a repeat loop is used if you want to copy and paste the same set of code in reverse order.

c)
The output gear needs to be larger than the input gear.
d)
The driven gear needs to be larger than the driving gear.
10.
