WORKING AREA
Working area will be divided into three parts:
- Stage (Left side): Shows the result of your program on pressing the RUN button.
- Toolbox (Middle): The toolbox contains blocks which you can use to build a program in the workspace.
- Workspace (Right side): The area where blocks will be dragged into and attached with one another for building a program.
- Dragging a block to workspace: Click and drag a block until it is completely in the workspace, then let go.
- Connecting the blocks: Stack blocks vertically as they will execute from top to bottom. The blocks will snap together like a magnet. When the blocks are connected, you will hear a “click” sound.
- Disassembling and Reassembling the blocks: In case you placed the wrong block in the code construction area, you may correct the error by disassembling and reassembling the blocks in the correct manner.
- Deleting a block: Any unwanted block in the workspace may be deleted. There are three ways to delete a block: a. Drag it to the trash can. b. Drag it back to the toolbox. c. Highlight a block, and press “Backspace” or “Delete”.
- ‘Move’ block
This moves Roby forward one step (not all the way) if he is not facing a wall. - ‘Turn’ block
This turn Roby left or right 90 degrees. Click on ”left” for the option to switch to ”right”. - ‘Repeat’ block
Use this to do some statements again and again (without creating multiple copies of the statements). This block can be treated as a “parent block”, which you can plug “child blocks” into.- Note that it only repeats the enclosed statements.
- The example above is like “move forward, turn right, move forward, turn right, move forward, turn right…” until finished.
- ‘If’ block
If there is a path ahead, do the enclosed statements. Important: click on “ahead” for other options. Always click into highlighted text areas to explore what the block contains.
- ‘If-else’ block
If there is a path in the specified direction, do the first action or set of actions. Else, do the second one (“else” means “if there is not…”). - Nested Ifs
Sometimes you need to layer the if statements, to check for other conditions given a certain condition. For example:
- Limited Blocks
Some of the levels limit how many blocks you can use to solve the maze. When you hit that limit, the toolbar will be locked. To use a new block, you need to delete an existing block on your workspace.
Once the required blocks have been placed in the workspace, test your program by pressing the RUN button.
Navigating a robot through a map to successfully reach a designated destination is very much akin to the intricate process employed in the navigation systems of self-driving autonomous cars like Tesla 8.0.
Just as a robot must interpret its surroundings, plan its path, and adapt to unforeseen obstacles, autonomous cars utilize an array of sensors, sophisticated algorithms, and real-time data to maneuver safely through bustling streets.
LEVEL 1
What’s new to learn:
Using ‘Move’ block more than once.
Same statement may need to be executed more than once to complete the task.
Task:
You have to move forward appropriate number of times to reach the goal.
Hint:
Use the ‘Move’ block appropriate number of times to reach the goal.
Solution
LEVEL 2
What’s new to learn:
Using same and/or different statements more than once in correct sequence.
More than one statements may need to be executed one after another in correct sequence to complete the task.
Task:
You have to first move forward, turn left, again move forward, turn right and once again move forward.
Hint:
Use ‘Turn’ block and ‘Move’ block appropriate number of times and in proper sequence to reach the goal.
Solution
LEVEL 3
What’s new to learn:
Using ‘Repeat’ block to execute one statement repeatedly.
One or more statements enclosed in the Repeat block will be executed repeatedly until the condition set in the Repeat block is satisfied.
This is called Loop in computer coding language. The enclosed statements will be executed on each run (or iteration) through the loop. The loop is set to stop once the condition is satisfied.
Task:
You have to repeatedly move forward until you reach the goal.
Hint:
Use Repeat block to move forward until you reach the goal.
Solution
LEVEL 4
What’s new to learn:
Using ‘Repeat’ block to execute more than one statement repeatedly.
Sometimes a sequence of statements needs to be executed more than once to complete the task.
Task:
You have to first move forward, turn left, again move forward and turn right. You have to repeat these steps until you reach the goal.
Hint:
You learnt using ‘Move’ block in Task 1, ‘Turn’ block in Task 2 and ‘Repeat’ block in Task 3.
Enclose ‘Move’ block and ‘Turn’ block appropriate number of times and in proper sequence within the ‘Repeat’ block to reach the goal.
Solution
LEVEL 5
What’s new to learn:
Using a sequence of statements and then ‘Repeat’ block.
Sometimes one or more statements may need to be executed first before using the ‘Repeat’ block to complete the task.
Task:
You have to move forward twice and then turn left and again move forward until you reach the goal.
Hint:
Use ‘Move’ block, ‘Turn’ block and ‘Repeat’ block in proper sequence.
Solution
LEVEL 6
What’s new to learn:
Enclosing ‘If’ block in the ‘Repeat’ block.
One or more statements enclosed in the If block will be executed if the condition set in the If block is True.
Task:
You have to move forward and then check if there is a path to the left, you’ll turn left. You have to repeat these steps until you reach the goal.
Hint:
Enclose ‘If’ block (to turn left if there is a path to the left) and ‘Move’ block (to move forward) within the ‘Repeat’ block.
Solution
Alternative 1
Alternative 2
LEVEL 7
What’s new to learn:
Enclosing ‘If’ block in the ‘Repeat’ block.
One or more statements enclosed in the If block will be executed if the condition set in the If block is True.
Task:
This Task is identical to TASK 6 except for that in TASK 6 you have to turn left and in this TASK 7 you have to turn right.
You have to move forward and then check if there is a path to the right, you’ll turn right. You have to repeat these steps until you reach the goal.
Hint:
Enclose ‘If’ block (to turn right if there is a path to the right) and ‘Move’ block (to move forward) within the ‘Repeat’ block.
Solution
LEVEL 8
What’s new to learn:
Enclosing multiple ‘If’ blocks in the ‘Repeat’ block.
More than one ‘If’ blocks may be enclosed in the ‘Repeat’ block.
Task:
This Task is a combination of TASK 6 and TASK 7. In both TASK 6 and TASK 7 you enclosed only one ‘If’ block within the ‘Repeat’ block but in this TASK 8 you have to use two ‘If’ blocks within the ‘Repeat’ block.
You have to move forward and then check if there is a path to the right, you’ll turn right and in case if there is a path to the left, you’ll turn left. You have to repeat these steps until you reach the goal.
Hint:
Enclose ‘Move’ block (to move forward) and two ‘If’ blocks (to turn right if there is a path to the right and to turn left if there is a path to the left) within the ‘Repeat’ block.
Solution
Alternative 1
Alternative 2
LEVEL 9
What’s new to learn:
Using ‘If-else’ block within the ‘Repeat’ block.
One or more statements enclosed in the If block will be executed if the condition set is True otherwise one or more statements set in the else block will be executed.
Thus, If-else block allows you to adopt different paths depending upon whether the condition set is True or False.
Task:
You have to move forward if there is a path ahead. Otherwise, you’ll turn left. The whole process is repeated till the goal is reached.
Hint:
Enclose ‘If-else’ block (to move forward if there is a path ahead or else turn left and then move forward appropriate number of times) within the ‘Repeat’ block.
Solution
LEVEL 10
What’s new to learn:
Using ‘If-else’ block together with ‘If’ block within the ‘Repeat’ block.
Challenge yourself and reach the goal using all the concepts learned during the lesson.
Solution
Alternative 1
Alternative 2
You must have observed that sometimes the same problem can be solved in different ways. The solutions depend on your unique Computational Thinking skills. Computational Thinking enables you to solve problems differently. It develops out-of-the-box thinking skills.
That’s the whole point of this IGNITE course.
