Light Bot

---

Objectives

• Experience an icon-based robot programming environment
• Learn to work with a partner,
  
• Create programs using the given programming icons

Although this lab report must be completed individually, please consult with one another.

In this lab, work with a partner to play at least 8 levels of a game called Light Bot (http://armorgames.com/play/2205/light-bot)

Use only one laptop for playing and one for reporting, switching off after each level.

I apologize that the first screen is a bit confusing. Even if it keeps saying that it is loading, just push the play button anyway.

It's a Flash game, so you should be able to play it in any current Windows browser.

The Recorder will be submitting the lab report and the partner will be submitting just a list of who did what. All lab reports should be self-contained and should contain the NAMES and their primary roles each member played at the top. Such as the following:

Lab number: L0
Teams members: name1, name2

• Odd Level Player: player1name
• Recorder and Even Level Player: player2name

Your team will submit a Lab Report entitled YourUserName1-YourUserName2-L0-report.docx

(Please do not use any other filename because the TAs need to be able to identify downloaded files by author and assignment.) In your Word document, you will work together to answer the following questions. I recommend that you read the questions before playing so you know what to look for while you're playing the game.  Be sure to answer each question fully in complete sentences.

1. In Light Bot, there are seven block icons which you can use for writing your program. Working with your partner, identify each  and describe how each one works.
1. 
   
2. 
3. 
4. 
5. 
6. 
7. 
   
   

2. The name of and are called functions. In your own words describe in additional detail what a function does and why is it useful.
   
   
3. Consider the three programs shown in the image (at right). Assuming the icons work like Light  Bot, identify which (if any) of these gets Light Bot to the goal square in the game above. (The goal is blue, the walls are grey---Light Bot cannot walk through walls, and if she tries, she stays in the square where she is.) Note that program 3 wraps onto a second line because it is so long.  Explain how you know this is the correct program.
   
   
4. If one of the programs given in the image gets Light Bot to the goal, it still migh not be an optimal program. An optimal program is one that uses a minimum number of instructions. Write an optimal program to get Light Bot to the goal.
   
   
5. While you were working your way through Light Bot, you and your partner may have made some mistakes. What mistakes did you make and how did you go about correcting them?
   
   
6. What was the highest level you reached?
   
   
7.  What was the most surprising thing you and your partner encountered while working through the puzzles in Light Bot? Describe why it was surprising.
   
   
8. Come up with three questions you and your partner would like answered about programming. Be prepared to share them with the rest of the class in discussion.

When you are finished, save the report as YourUserName1-YourUserName2-L0-report.docx. Share the report with the partner who is not the recorder.

• The Recorder and Even Level Player should submit the report file YourUserName1-YourUserName2-L0-report.docx to the appropriate location in Moodle before our next class.
• The Odd Level Player should submit a file named YourUserName1-YourUserName2-L0-team.docx with the following:

  Lab number: L0
  Teams members: name1, name2

  • Odd Level Player: player1name
  • Recorder and Even Level Player: player2name
