A lot of people have been trying to figure out how to get Cozmo and Vector to talk. After some feedback from the mailing list Kinvert programmed them, and now Cozmo and Vector talk.

Both Vector and Cozmo are an amazing way to learn programming. If you want to know the differences between the two check out Cozmo vs Vector.

This is one of many wonderful Vector Coding Examples. Actually, it’s also a Cozmo Coding Example. This is a Kinvert first! Both robots being programmed in one article.

Vector and Cozmo Talking?

﻿

You’ll really want to watch the video. It’s well worth the <2 minutes. Here is a link in case you need it: https://www.youtube.com/watch?v=c_i_lVhOUBw

Again, this is something a lot of people have been wanting a long time.

Please keep in mind, this is in the very early stages and they can only say “Hi.”

What is really exciting is the potential of the method we are using. It will be pretty easy to get them to each have 4 options of what to say. But honestly they could also easily have 256 things to say. Or more.

More on that later.

Speaking of Cozmo and Vector Commands…

What commands will we be using? Here they are:

robot.behavior.drive_off_charger()

robot.behavior.set_lift_height()

robot.say_text()

time.sleep()

robot.world.wait_until_observe_num_objects()

cozmo.anim.Triggers

robot.play_anim_trigger()

The program itself isn’t that hard. The hard part for most people will be having two systems running the SDK for Vector and Cozmo.

Let’s Talk About the Cozmo and Vector Code

There are two different programs here. One is for Cozmo and the other is for Vector.

I’ll get a more detailed description soon. For now I’m trying to get the code out ASAP then get more detailed later.

To make this work you’ll need both the Anki Vector SDK and the Anki Cozmo SDK.

Vector’s Code

Cozmo’s Code

Python Code Improvements

Eventually we want to trigger this without touching Vector’s back. Can you think of ways to accomplish that?

How would you reverse it so Vector is waiting for Cozmo to talk?

What method could we use to increase the number of things Cozmo and Vector can say to each other?

Have any cool ideas for what they should do? Please let the world know in the comments below.

This is true whether your somewhat advanced or a complete newb like I once was.
