3.3 Colour sensor compare

ExplanationThe colour sensor compare block is just a modified wait block. Instead of a Time Indicator, we change it to a Colour Sensor that compares either the reflected light or the ambient light.

Robotics 101



In the tutorial example, we are comparing the Reflected light. When the Colour Sensor is in Reflected Light Intensity mode, a red LED light on the front of the sensor will turn on. If the sensor is close to an object or surface, this red light will reflect off of the object and then enter the sensor to be detected. You can use this to measure shades of colour on a surface or object, because darker shades of colour will reflect less of the red light back to the sensor.

You can use this mode to, for example, make your robot follow a black line on a white surface. As the sensor passes over the black line, the light measurement will gradually decrease as the sensor gets closer to the black line. This can be used to tell how close the robot is to the line.

In Reflected Light Intensity mode, the Colour Sensor detects the intensity of light that enters the sensor. The intensity of the light is measured as a percentage from 0 to 100, with 0 being very dark, and 100 being very bright.

We then compare using standard mathematical operators:

3.4 Ultrasonic sensor compare

Explanation

The Ultrasonic Sensor can measure the distance to an object in front of it. It does this by sending out sound waves and measuring how long it takes the sound to reflect back to the sensor. The sound frequency is too high for you to hear (“ultrasonic”).

You can measure the distance to an object in either inches or centimetres. You could use this, for example, to make your robot stop a certain distance from a wall.

The ultrasonic sensor compare block is just a modified wait block. Instead of a Time Indicator, we change it to an Ultrasonic Sensor that compares the distance in cm.

We then compare using standard mathematical operators:

Robotics 101

The Ultrasonic Sensor can give the following data:

Data Type Range Notes

Distance in Centimetres Numeric 0 to 255 Distance to object in centimetres.

Distance in Inches Numeric 0 to 100 Distance to object in inches.

Challenge 2

Cause your robot to do the following for 10 seconds:Whenever there is an object that is less than 20 cm from the robot’s ultrasonic sensor, the robot

should move backwards, away from the object.Otherwise, the robot should move forwards

After 10 seconds have elapsed, your robot should stop moving.

The Gyro Sensor detects rotational motion. If you rotate the Gyro Sensor in the direction of the arrows on the case of the sensor, the sensor can detect the rate of rotation in degrees per second. You can use the rotation rate to detect, for example, when a part of your robot is turning, or when your robot is falling over.

In addition, the Gyro Sensor keeps track of the total rotation angle in degrees. You can use this rotation angle to detect, for example, how far your robot has turned.

The Gyro Sensor can give the following data:

Data Type Notes

Angle Numeric Rotation angle in degrees.Measured from the last reset. Reset with the Reset mode of the Gyro Sensor block.Rate Numeric Rotation rate in degrees per second.

So, the wait block says, wait or keep the move block spinning until the robot has spun 45 degrees.

3.8 Switch

Explanation

The Switch block is a container that can contain two or more sequences of programming blocks. Each sequence is called a Case. A test at the beginning of the Switch determines which Case will run. Only one Case will run each time the Switch is executed.

The Switch test shown here can decide which Case to run based on a sensor data value or a value from a Data Wire. After one Case is selected and run, the program continues with any blocks after the Switch.

Robotics 101


http://localhost:58401/localizedMapping_B90BDB05-F70E-4B0B-8CEA-031DCF197215/en-GB/editor/page.html?Path=editor%2FDataWires.html

For our program, the switch block tests to see if the reflected light intensity on the ground is less than 50 (from the light sensor). Ie. Is it black or dark coloured. If it is, the robot turns to the right (towards the white).

Motor C off, B on

Or right motor on

If it is not and the intensity is greater than 50 (lighter), then it turns to the left , towards the black line.

Motor B off, C on

Or left motor on

This then loops forever

Robotics 101

This then loops forever

NOTE: The simplest of line-following programs will be a dual-state program, where the colour sensor either sees black or white and adjusts accordingly. The robot is not actually trying to follow the line but is trying to find the edge of it.

Single Light Sensor, no Ultrasonic Sensor


For your Robot (digital computer system) to work and function, to solve your problem, you need to think about what data goes into the system and then how the system uses it to provide and output or action that functions to solve your problem.

4.1.1 Input, process, output (IPO) table

This strategy has a robot with a single Light Sensor. Define how data will be used in your robot system by filling in the table below.

NOTE: You may also have a Gyro Sensor to help you turn, so include this as well

Input (event/data) Processing (coding) Output (action)

Eg:


Ultrasonic sensor receives signal

Calculate distance to opponent object and decide action to take

Move towards opponent

4.1.1 Robot design considerations and methodologies used

Define how you will construct your robot and why you have chosen to configure it this way. Include photos of your completed build.

4.2 Solution Design AlgorithmIn simplest terms, an algorithm is the series of steps that you can take to solve a problem. Here is one that represents the solution with a flowchart. You may like to do something similar.

An easier way to write an algorithm is to use pseudocode or English-like statements. For example:

Algorithm for edge detection

EG

Stop motorsReverse motors at -50 for 1 rotationSpin around (motor B -100, motor C 100)

If sense colour that is greater than 50 (white), then:

Else it is black, so drive forward (motor B 100, motor C 100)

Loop forever

Design your solution by developing an algorithm that incorporates decision making (switch) and repetition (loops)

Ideas

Move forward

StopReverseTurn full right for ?

If see white

Loop Forever

OR

If we see black, then (we must be in the middle) attack by moving forward

Drive backwards for 1 rotationTurn right 46 for 1 rotation

5.2 Work Logs

Work log

A work log is a short, bullet point list of what you worked on, and how long it took. Stick to just the facts. It shouldn’t take more than thirty seconds or so to write up a work log.

Sample work log:Backpack Project #1: Cave Exploration System

3/31: Worked on getting Builder to navigate uneven hallways (45 min.)4/1: Added Say blocks at each point so we could stop it from getting lost all the time (30 min.)4/3: Completed exploring simple caverns, now working on more complex systems (45 min.)4/4: Coded for multi-level caves, spawner detection system (30 min.)

A Reflection is like a journal entry that tells the story of your learning throughout the past week. Go through your work logs for the week and look at what you did, where you got stuck, and how you figured it out. Then write a 150- to 300-word Record of Thinking essay each week of the final project addressing the following:

Describe something that surprised you this week as you worked on your project.

Describe a moment where you go stuck. How did you get unstuck?

Did anyone help you this week? Who and how?

Choose an adjective that describes how you are feeling about your project this week. Explain why you chose this word.

What are you working on next week?

If you had more time to work on this project, what would you add? (for the final week)

Reflection Excerpt:

Week of April 6:

I finally figured out why my code wasn’t working. I had the wrong for loop nested inside the other one, and so it was executing way more times than it was supposed to, and that was why the Agent kept going off track. Once I created another variable to keep track of the number of times the Agent came back to the Home row, and checked this variable each time during the loop, everything worked the way it should. I only was able to figure this out because I took each function apart separately and ran it without that function in order to track down where the problem was. That was useful. I have to remember to try this first next time.

Game Playing – Basic Strategy

There are two major tasks that your SumoBot will need to be able to do in order to be competitive.

Firstly it needs to be able to find the edge of the ring and then turn around. At a basic level if your Bot can continually drive forward to the edge of the ring and turn around you can enter the SumoBot competition

1.

Secondly it needs to search for the opponent and charge when the opponent is located, while still staying in the ring.

Stay on the field. For this you will almost certainly need at least one light sensor to detect the ring's white edge. We highly recommend two such light sensors placed at the front corners of your robot. This will increase your chances of detecting the edge when coming at it from an angle. You can also adjust your retreat behavior so the robot will be less likely to exit the ring. A retreat behavior usually consists of backing up and turning back toward the center of the ring or scanning for your opponent. You can back up curving away from the sensor that detected the edge first. A third edge detector could be placed at the back of your robot - but this is almost never needed. It would be only useful if you have a behavior that could trigger backing up when the rear of your robot is close to the edge. Theoretically you could detect the edge when being pushed backward by your opponent and try to twist out of the way, but we've never witnessed anyone pulling off this advanced behavior.

Variables are a programming tool that allows the programmer to give a name to a certain value. That value can be used or changed over and over again in many different places. For instance, if you create a variable called Seconds and set it equal to the number "5", you can tell your robot to move forward for Seconds amount of time, or 5 seconds. You can tell your robot to move backwards for Seconds amount of time. If you want to change the amount of time the robot moves forward and backward to 6 seconds each, you only have to change it in the Seconds variable block instead of in both the forward and backward blocks.Goal: Use a variable to make the robot to move for a certain number of seconds.Skills Addressed:

Variables•Movement•InstructionsIn a new program, create a variable by dragging in a Variable block. Name the variable “Seconds” by clicking on the white bar at the top right of the block, then click on "Add Variable" and type in “Seconds” in the new field.

1.

Keep the Mode Selector Write - Numeric but change the parameter Value to "5" by clicking on the 0 and typing "5".

2.

Now you want to use the value. Add another Variable Block and change the Mode Selector to Read - Numeric.

3.

Add a Move Steering block and set the Mode Selector to "On for Seconds". 4.

Now drag the suitcase tab from the second Variable block into the Seconds parameter of the Move Steering block.

5.

VARIABLES: BEGINNERMonday, 5 August 2019 12:54 PM

Robotics 101

HINT: This is called a “Data Wire”. The value of the Seconds variable is “read” into the “seconds” value of the motor block.

Test the program6.

HINT: Observe the robot as you test it. Did the robot do what is was supposed to? If not, how can you figure out what went wrong? What can you do to fix it?

Alter the value of the variable and watch how the movement changes.7.Challenge Expansion: Now that you can use a variable, add onto the program. After the robot moves forward for Seconds amount of time, make it move backwards using the same variable.

8.

DiscussionAfter the team has completed the challenge, ask them the following questions to get them to think through the programming challenge.What was hard about this programming challenge?1.What was easy?2.Did the robot do what you intended it to do?3.How did you go about solving the problem?4.What could you do differently next time? 5.

In previous challenges, you have set the value of variables manually. Variables, however, can also be calculated at runtime (while the program is running). In this challenge, you will write a program to calculate the circumference of your robot’s wheels, store the value in a variable, and then use the variable to move a certain distance.Goal: Program the robot to drive a given distance by using the Math block to calculate the circumference of the robot’s wheels.Skills Addressed:

Variables•Math Block•Movement•InstructionsIn a new program, create 3 variables: "Power", "Diameter", and "Distance".1.

Set the Power variable value to "25".2.Now measure the diameter of your robot’s wheels. Set the Diameter variable to the value you measured. For this example, you’ll assume the wheel diameter is "2.5" inches. Set the Diameter variable value to "2.5".

3.

Set the Distance variable to the distance in inches you want your robot to travel. Set the Distance variable value to "64".

4.

Now you can calculate the circumference of the wheels. Add a Variable block and a Math block to the program. Alter the variable settings to "read" the value of Diameter.

5.

Use the Math block to multiple Diameter by Pi (3.14). Change the math function to “Multiply,” use a Data Wire to read Diameter into "A" input, and change "B" value to “3.14”.

6.

Next, create a new variable named "Circumference". Use a Data Wire to read the “=” value of the Math block into the variable. This will store whatever number the Math block calculates in the Circumference variable.

Now you can calculate the distance you want the robot to travel. By dividing the distance you want the robot to travel by the circumference of the wheel, youy get the number of wheel rotations needed to travel that distance. Use a Math block to perform this calculation.

8.

Add a Move Steering block and set Mode Selector to “On for Rotations.” Use the value you just calculated for the rotations parameter of the Move Steering block and use the Power variable for the power parameter.

9.

HINT: Moving by rotations instead of by seconds is a much more accurate way to move your robot. If the robot’s batteries are low, the robot will move more slowly and therefore cover less distance in a given number of seconds, but the number of rotations will always stay the same.

Run the program and measure to see if the robot moved the correct distance.10.


HINT: A good troubleshooting method is to explain every step of your program to another person. Often the problem will become clear simply by reading the steps out loud.

Test the program using various distance values.11.DiscussionAfter the team has completed the challenge, ask them the following questions to get them to think through the programming challenge.What was hard about this programming challenge?1.What was easy?2.Did the robot do what you intended it to do?3.How did you go about solving the problem?4.What could you do differently next time? 5.

Did you know that you can create your own programming blocks? They are called "My Blocks." My Blocks allow you to define a set of programming instructions that can be used over and over again by only placing a single block into the program. Learn more by completing the Robot Educator - Tools -My Blocks tutorial.


As you saw in the Robot Educator My Blocks tutorial, My Blocks can be used to create repeatable code. Another thing My Blocks can do is receive values from other blocks. These are called parameters. The value of a parameter is unknown until the programmer sets it using another block. In this challenge, you will create a My Block to move for an unknown number of seconds. Just as you have to send a Seconds value to a Move Steering block, you will also have to send a Seconds value to this parameter.Goal: Create a My Block that moves at 50 percent power for an undetermined number of seconds.Skills Addressed:

My Blocks•Variables•Movement•InstructionsIn a new program, replicate the program from the Variables Beginner challenge.1.

Now you can create a My Block of this code. First, select the Motor block by clicking it.2.

Then select Tools > My Block Builder from the top menu.3.A menu will appear. Set up the MyBlock with the following steps:4.In the “Name” field, type “MoveForwardForSeconds.”5.

2.

HINT: 3.My Blocks can be named anything you want, but it is a good idea to be very specific with the name so you can remember what it does.

4.

In the “Description” field, type “This MyBlock moves forward at 50 power for a certain number of seconds.”

Click the Parameter Icons tab and select an image that represents time.10.

Then click “Finish.”11.The Move Steering block in your code should be replaced with your new My Block. Test your program to make sure it works.

12.

Robotics 101

Now add a wait block and another MoveForwardForSeconds block to your code. Input the Seconds variable to the new MoveForwardForSeconds block.

13.

Test your program. Your robot should move forward for five seconds, wait, and then move forward for another five seconds.

14.


Try your program using different values for Seconds. Does the amount of time the robot moves change for both times the My Block is used?

15.

HINT: You can also edit the blocks of the My Block by double clicking on it in your code. A new tab will open where you can alter the My Block.

My Blocks can be as complicated as you want them to be. Turning a complicated set of code into a My Block can help make your program look much cleaner, as well as making it very easy to repeat lengthy processes with a single block. In this challenge, you will alter the Variables Advanced challenge to use a My Block to calculate the number of rotations the robot needs to move. The My Block will take in two parameters, diameter and distance, and then calculate the number of rotations the motors must turn in order to travel the required distance.Goal: Create a My Block that will calculate the number of rotations the motors need to move in order to travel a certain distance.Skills Addressed:

My Blocks•Variables•Math Blocks•Movement•InstructionsIn a new program, replicate the program from the Variables Advanced challenge.39.Now you can create a My Block to calculate the number of rotations the robot needs to move. First, select the set of code shown below..

First, select the set of code shown below..

Then select Tools - My Block Builder from the top menu.41.In the menu, give the My Block a "name", "description", and "icon".42.Select the "Parameter Setup" tab.43.Name the first parameter “diameter” with a default value of "0" and select an icon.44.

Now click on the second parameter. This is the value the My Block will calculate and output back to the rest of the code. Name it “rotations” and select an "icon".

45.

Robotics 101

In order to calculate the number of rotations, we need to know both the wheel diameter and the distance the robot needs to travel, but right now we only have an input parameter for diameter. Press the “+” button to add a new parameter.

46.

Set up the new parameter with the following attributes:47.Name: “distance”48.Parameter type: "Input"49.Data Type: "Number"50.Default Value: "0"51.Select an icon that represents distance.52.

Robotics 101

Click “Finish”.53.A new tab will open showing your new My Block code.54.

HINT: Notice your two input parameters (diameter and distance) in the first block on the left and your output parameter (rotations) on the far right.

Since we created a “local” parameter to read in the distance from the outside code, we don’t need to read the Distance variable in the middle of the code. Delete this block.

55.

Now connect the distance parameter on the left to the ‘A’ input of the second calculation where the old Distance variable was connected.

56.

Robotics 101

Return to the main code by selecting the original program in the tab bar. The section of code you selected earlier should be replaced with your new My Block.

57.

HINT: The blocks may be jumbled and unorganized. Feel free to rearrange them. If the Data Wires are in the way, simply click on one of the wire ends to disconnect it, and then reconnect it the way you want.HINT: Also notice that the rotations output parameter of the My Block connects to the rotations parameter of the Move Steering block.

Notice that the original Distance variable is not connected to the distance parameter in the CalculateRotations My Block. Read it into the My Block using a Variable block and a Data Wire.

58.

Test your program to make sure it works.59.


Try your program using different values for Distance.60.Think about other way you can use My Blocks. What tasks do you program over and over again? Would it be easier to put them into a My Block so you could reuse them?
