Final Assessment

Reading Code:

In order to describe how a robot will react to code when given code only, you need to understand how all of the code blocks work. It is more than just retyping the blocks into sentences; you need use your knowledge of each code block to BE the robot.

Example of retyping the code, but not understanding it:

The robot will start moving at 20, 20 speed. It will wait until the yaw angle equals 90, and then it will stop moving. ​

​This student has simply retyped what the code says. However, their answer gives no indication that they understand this code or how to robot will react. A robot following this code would not do all of that; it would just move forward forever.

Part 1: Understanding start moving blocks.

The first step to being able to read code and know how a robot will react is to understand how the blocks work.

Multiple Choice

How would my robot react to this code?

This question checks if you understand how programs flow

(move from one block to the next).

• It would start moving forward, then it would do a pivot turn to the left, and then it would stop moving.

• It would move forward forever.

• It would turn to the left forever.

• It wouldn't move at all.

Programs run from top to bottom.

The purpose of a wait block is to prevent a program from moving on to the next block until a specific condition (time, distance, yaw angle, button pressed, etc) is met.

Multiple Choice

How would my robot react to this code?

• It would do a left pivot turn until facing the right, then stop and have a happy face forever.

• It would do a right pivot turn until facing the right, then stop and have a happy face forever.

• It would do a right pivot turn until facing the right. Then, a happy face would be on the screen forever.

• It would do a right pivot turn forever; however, after it reaches a yaw of 90, it would have a happy face while it turns.

Part 2: Debugging

When you are looking for errors in a program, you are looking for things that will make the robot NOT behave how we want it to. There are always many ways to code the same outcome. It is only an error if it causes the robot to behave incorrectly.

​Error or Preference?

Multiple Choice

I want my robot to drive forward until it see the color red and then turn 90 degrees to the left. Which program(s) have an ERROR?
