TIPS!

Sometimes, the text

inside the blocks are

so small on the

Scratch screen that

it’s difficult to read.

Let’s learn how to

change the font size

for texts inside the

blocks.

Learning objectiveCode to make RQ-HUNO stand up from its lying position.

1. Learn how to make RQ-HUNO stand up (Stand A, B).

Standing up when facing the sky (Stand A)

Standing up when facing the floor (Stand B)

Using Scratch’s ‘More blocks’ and ‘Control’, let’s code to distinguish whether the robot is

facing the sky or facing floor.

*Stand A and B motions are some of the basic behaviors including in RQ-HUNO’s firmware.

2. Learn how to make RQ-HUNO stand up when it hear a voice.

SCRATCH BUILDER 30

03 PROGRAMMING PRACTICE:WAKING UP RQ-HUNO

SCRATCH BUILDER 31

1. How to make RQ-HUNO stand (A,B)1) Select ‘More blocks’ to use special blocks to

control RQ robots.

2) From different blocks in the More blocks, use ‘Call motions’ to select ‘Button A’ (Stand A).

[List of Call motions]

CA

DB

See that they

represent the buttons

on the remote.

SCRATCH BUILDER 32

3) Drag and drop ‘Call motions’ block to the script area then select ‘Button A’ from its drop

down menu.

4) Then use the ‘Wait ( ) secs’ block from ‘Control’ section. We need this block to secure

enough time while ‘Button A’ (Stand A) is in action.

5) ‘Button A’ motion requires about 2 seconds. Not to interrupt the next block, use ‘Wait ( )

secs’ block to secure enough time. 3 seconds are better than 2 seconds for stability.

6) Put down RQ-HUNO as shown in the picture and click the Scratch block. RQ-HUNO then

stands up from its lying position.

Now that RQ-

HUNO stood up.

Let’s make it walk.

SCRATCH BUILDER 33

7) The block below will make RQ-HUNO stands up and takes a step forward.

8) Select ‘Repeat’ block from ‘Control’ section, then place it above the ‘Call motions button↑’block. Then change the time to 3.

Let’s make RQ-

HUNO walk

further!

Let’s run the code

and see what

happens.

When the Scratch block is running, a yellow band forms around

the blocks. When the yellow band is gone, it means the Scratch

block motion has ended.

TIPS!

SCRATCH BUILDER 34

9) Put down RQ-HUNO as shown in the picture and click the Scratch block. RQ-HUNO stands

up and takes 3 steps forward.

10) To play a melody while RQ-HUNO is in motion, let’s use ‘Sound on/off’ blocks from ‘More

blocks’.

11) Put down RQ-HUNO as shown in the picture and

click the Scratch block. RQ-HUNO stands up and

takes 3 steps and the melody plays. Once the motion

has been completed, the melody also stops.

This time, we are going to

make a melody play while

RQ –HUNO is in motion and

stop when all motions are

finished

SCRATCH BUILDER 35

12) The Scratch blocks below is for making RQ-HUNO stand up when it falls face down

(Stand B).

13) Put down RQ-HUNO (Facing down) as shown in the picture and click the Scratch block.

RQ-HUNO stands up and take 3 steps forward with playing the melody. Once the motion has

been completed, the melody also stops.

2. How to make RQ-HUNO stand up when it hears a voice.

1) Let’s make Scratch blocks as shown in the picture below. Use the same blocks from

previous chapter.

Use the same blocks we

made from the chapter 1. We

add more lines to make RQ-

HUNO hears a voice.

Let’s find out how we can use

to detect a voice.

SCRATCH BUILDER 36

2) Drag ‘Sound sensor’ block with the mouse to insert into .

3) Enter 50 as the basic sound volume in the blank. This means ‘The value of detected sound

is greater than 50’.

From ‘More Blocks’, check , thenwill appear on the top left stage.

If the robot’s power is on and the communication connection has been made properly, the volume of sound around the robot is displayed with a number.When using the sound detection function in Scratch, check the volume of sound measured before setting a basic value.For example, if the volume of sound measured is 60, set the basic value to 50 for stable sound detection.In other words, it is better to set the basic value a slightly lower than the actual measurement.For reference, the sensor values for the sensors other than Sound sensor block will not appear immediately.

TIPS!

SCRATCH BUILDER 37

4) Select ‘If then’ block from Control blocks to make blocks as below.

It is the part that says ‘If the value of sound measured is greater than 50, then execute XXXX.’

Drag the conditional phrase block to cover the block that you created already.

5) A conditional block like ‘if’ may not work even blocks have been inserted into ‘if’ part. This

is because it only performs once and then does not repeat. Use ‘Forever’ block from

Condition block section to repeat specific blocks infinitely.

You can not detect sound

only with .

You will need a conditional

block.

Condition

Execution

We use ‘Forever’ block with ‘If’

block to detect sound at any

time.

SCRATCH BUILDER 38

6) Lastly, place ‘Wait ( ) secs’ block under ‘Sound off’ block, then put 1 second in the blank

7) Put down RQ-HUNO as shown in the picture and click the Scratch block. When you click, it

does not do anything. But when you shout, “Wake up”., or clap to make some noise, RQ-

HUNO stands up and take 2 steps forward with playing the melody.

8) If you change ‘Call motions block’ as below, RQ-HUNO will stand up and move 2 steps

when RQ-HUNO lays face down.

If there is no ‘Wait 1 secs’ block, the

program starts from the beginning as

soon as the sound is turned off with

‘Sound off’ block, then it can detect the

sound from robot moving. That is why it

waits for one second after the sound is

turned off.
