Robot Troubleshooting
1. Which Robot are You Using?

Detecting  Multiple  Colors

One of the features that makes EZ-Robot so special is that the camera that can detect faces, objects, glyphs, QR codes and multiple colors.

For this tutorial, we will use the JD Humanoid, however, this process can easily be applied to any EZ-Robot configuration.

What You Will Need

  • JD, Six, Roli, AdventureBot or Developer Kit
  • Windows PC with ARC (formerly EZ-Builder) installed

Instructions

EZ-Robots can be easily programmed to recognize multiple colors at the same time, and then you can use variables to have your robot respond differently to different colors.


Step 8

Within the Camera Control, click on the Settings/Configuration button.  In ARC this is the Three Dots in the top right corner of the window.  In EZ-Builder, it's the Gear button in the bottom left corner.

​​Within the Config Dialog window, click on the "Scripts and Variables" Tab, and then click on the "Start Tracking" Script box.

*Note: Your robot will perform the script you define in this box each time the robot starts Tracking a color or object.  This Script field does not define when a robot will start tracking..  

Within the Scripting Interface you can choose to program in Blockly, Python JavaScript and EZ-Script.  This example will be shown in EZ-Script, so click that Tab. 
​
Type:
             SayEZB("I see " +

Note the empty space before the closing quotation mark above.  This will help your robot to leave a gap between the word "see" and the name of the color

Then Click on the Variables Tab in the upper right portion of the screen.

Locate and click the variable ($CameraObjectColor).

The variable will be added to your script.  Be sure to add a closing parenthesis to complete the command.  Once completed, your script should look like this:

          SayEZB("I see " + $CameraObjectColor)

When the robot speaks the above command, it will swap in the variable of the color the robot sees, to complete the phrase accurately.

Hit the SAVE button, and give it a Try!

Place the objects in front of the camera and the robot will tell you the color it sees.

Now that your robot can recognize different colors, try adding Actions like a Wave or Bow to your robot when it recognizes a color... and then add IF/ELSE statements to get the robot to respond differently to different colors.

Step 1

Load the JD Humanoid Example Project and connect to your robot.

Within the Camera Control panel, select the EZB camera, and click on the Start button.  

Step 2
​

Once your robot's camera is showing streaming video, click on the "Multi Color" Tab and delete any pre-existing colors that may be listed.

Click the Add button.

Step 3

Picture
Give this color a Name. 

Assigning a Name is important if you will be getting your robot to recognize multiple colors.  The Name field is actually setting the variable "$CameraObjectColor", which we will use later in the tutorial, to have the robot be able to differentiate between colors.

Step 4

Image A) Hold your object in front of the camera and make sure there aren't any other objects in the image with a similar color.

Image B) Rotate the white and black dots on the color wheel to isolate your color range.   It's not important that the robot be able to see the entire colored object, but it is important that it doesn't see other fragments within the image or the robot will think those fragments are also your selected color.

Image C) Use the Saturation, Luminance and Minimum Size sliders to remove other similar colors and bright areas in your image.

Image D) Once you have the color well isolated, press Save.

Once you have the first color set up, you can Add additional colors or simply work with a single color for the time being.  


Step 5
Picture
Once you have all the colors programmed, click on the Tracking Tab in the Camera Control Panel, and select "Multi Color".  This will start your robot tracking all the colors.  If you have Servo Tracking or Movement Tracking selected in the Settings/Config then the robot will perform that type of Tracking.

Step 6

Getting your EZ-Robot to 
recognize multiple colors has value, but having the robot be able to differentiate between colors will open up a world of possibilities.  This following steps will ensure that your robot is able to differentiate between different colors.  Programming a range of custom responses will be handled in the If/Else and Variables tutorial.

Step 7​

Within the Camera Control, click on the Settings/Configuration button.  In ARC this is the Three Dots in the top right corner of the window.  In EZ-Builder, it's the Gear button in the bottom left corner.
​
​​Within the Config Dialog window, click on the "Scripts and Variables" Tab, and then click on the "Start Tracking" Script box.

*Note: Your robot will perform the script you define in this box each time the robot starts Tracking a color or object.  This Script field does not define when a robot will start tracking..  

Step 8

Within the Scripting Interface you can choose to program in Blockly, Python JavaScript and EZ-Script.  This example will be shown in EZ-Script, so click that Tab. 
​
Type:
             SayEZB("I see " +

Note the empty space before the closing quotation mark above.  This will help your robot to leave a gap between the word "see" and the name of the color

Then Click on the Variables Tab in the upper right portion of the screen.

Locate and click the variable ($CameraObjectColor).

The variable will be added to your script.  Be sure to add a closing parenthesis to complete the command.  Once completed, your script should look like this:

          SayEZB("I see " + $CameraObjectColor)

When the robot speaks the above command, it will swap in the variable of the color the robot sees, to complete the phrase accurately.

Hit the SAVE button, and give it a Try!

Place the objects in front of the camera and the robot will tell you the color it sees.

Now that your robot can recognize different colors, try adding Actions like a Wave or Bow to your robot when it recognizes a color... and then add IF/ELSE statements to get the robot to respond differently to different colors.
