IBM TJBot

IBM TJBot

Maker Kits are a collection of DIY open source templates to build things with IBM AI services in a fun and easy way. IBM TJBot is the first maker kit in the collection. You can 3D print or laser cut the robot body, then use one of our recipes to bring him to life!

In addition, you can unleash your own creativity and create new recipes that bring TJBot to life using any of the available IBM AI services!

TJBot only works with a Raspberry Pi.

Build TJBot

You can make your own TJBot in a number of ways.

• 3d Print or Laser Cut. If you have access to a 3D printer or laser cutter, you can print/cut TJBot yourself. Begin by downloading the design files and firing up your printer/cutter.
• TJBot Full Kit. You can order a full TJBot kit with the laser cut cardboard and all the electronics from Sparkfun, Adafruit, or Robotkingdom.
• TJBot Cardboard Kit. You can purchase the TJBot laser cut cardboard from Texas Laser Creations.

Electronics

There are a number of components you can add to TJBot to bring him to life. Not all of these are required for all recipes.

• Raspberry Pi 3 + SD card preloaded with NOOBS. This is a required component to make TJBot work! 🤖
• LED. We recommend the NeoPixel RGB LED (8mm), although TJBot supports Common Anode LEDs as well. Note that if you are not using a NeoPixel LED, you may also need to add resistors between it and the Raspberry Pi. Neopixel LEDs do not require resistors.
• Female-to-female jumper wires. TJBot will only need 3 of these wires, so you’ll have extra.
• Female-to-male jumper wires. TJBot will only need 3 of these wires, so you’ll have extra.
• USB Microphone. Other brands of USB microphones should also work.
• Mini Speaker. We recommend any small speaker with the ability to connect to a 3.5mm audio jack. We've had much success with the Anker Mini Bluetooth Speaker, although this product has been discontinued as of 2018. For the best audio experience, we recommend using a USB Audio Adapter to avoid audio interference with the LED and to avoid difficulties in making Bluetooth speakers work reliably.
• Servo Motor. Note that the red (middle) wire is 5v, the brown wire is ground, and the orange wire is data.
• Raspberry Pi Camera. Either the 5MP or 8MP camera will work.

Assembly

Once you have obtained your TJBot, please refer to the assembly instructions to put it all together.

For reference, here is the wiring diagram to hook up a Neopixel LED and servo to your Raspberry Pi.

TJBot expects LEDs and servos to be connected to specific kinds of pins, including voltage (+3.3v or +5v), ground, and data. See https://pinout.xyz for a complete pin diagram. The tables below shows the default pins expected for different components, although these pin numbers can be overridden in TJBot's configuration.

Neopixel LED

PIN type	PIN Name	Physical PIN
Data	GPIO 18	Physical 12
Power	+3.3v	Physical 1
Ground	Ground	Physical 6

💡 Be careful when connecting the LED! If it is connected the wrong way, you may end up burning it out. The Neopixel LED has a flat notch on one side; use this to orient the LED and figure out which pin is which.

Common Anode LED

PIN type	PIN Name	Physical PIN
Red	GPIO 19	Physical 35
Power	+3.3v	Physical 17
Green	GPIO 13	Physical 33
Blue	GPIO 12	Physical 32

💡 Common Anode LEDs and Neopixel LEDs can both be connected to TJBot at the same time and will shine the same color. However, TJBot's head only has room for one LED!

Servo

PIN type	PIN Name	Physical PIN
Data (orange)	GPIO 7	Physical 26
Power (red)	+5v	Physical 2
Ground (brown)	Ground	Physical 14

Bring TJBot to Life

First, configure your Raspberry Pi for TJBot by running the bootstrap script.

curl -sL http://ibm.biz/tjbot-bootstrap | sudo sh -

Next, take a look at TJBot's recipes, which are pre-configured behaviors that bring TJBot to life using IBM's Watson AI services.

TJBot comes with these recipes to demonstrate different capabilities.

• Use Your Voice to Control a Light with Watson [instructions] [github]
• Make Your Robot Respond to Emotions Using Watson [instructions] [github]
• Build a Talking Robot with Watson [instructions] [github]
• Build a Robot Translator [github]

After checking out these recipes, we encourage you to take a look at featured recipes created by members of the #tjbot community!

tjbot's Issues

No Sound Output during wave.js

Hello,

using victordibias wave.js I managed to make Sherlock (which is what I call my TJBot) wave and (supposedly) dance to music. I say "supposedly", because the sound output is lacking, sadly. Testing with other applications my sound output works fine, its just wave.js this does not work with. I am using a USB speaker for sound output.

Error connecting to speech_to_text

When launching, errors look like this:

pi@raspberrypi:~/tjbot/recipes/speech_to_text $ sudo node stt.js
info: Hello from TJBot! My name is Watson.
I understand lots of colors. You can tell me to shine my light a different color by saying 'turn the light red' or 'change the light to green' or 'turn the light off'.
error: the speech_to_text service returned an error. type=error, isTrusted=false, _yaeti=true, , addEventListener=function _addEventListener(type, newListener) {
var
listenersType,
i, listener;

Then the command line gets into an endless loop.

Bluemix Credentials are checked and double checked. Any suggestions would be appreciated. Thank you.

using bluetooth mic

I'm trying to use a bluetooth mic with the STT app.
It exits just after it says
TJBot is listening, you may speak now.
[rpi-ws281x-native] This module requires being run with root-privileges. A non-functional stub of the interface will be returned.

When I use the plug-in USB mic, it works fine and prints what it thinks I said.
I can see the bluetooth mic in
pacmd list-sources ... it says it's at index 2.
But I don't know what to change in the micInstance config parameters to make it see this device.
Any hints, please?
Oh, I'm running this on Ubuntu Mate on a Pi 3, btw (as the bluetooth stuff doesn't work very well on Raspbian yet)

Wiring diagram

Please add the wiring diagram for the LED and the servo to this repo. I know that the Instructable has wiring for the LED but I don't see the wiring for the servo motor. Also it would be great not to have to hunt for these in Instructables, but rather have them right here. Thanks!

error: No speech detection for 60s

How can we avoid this error?

many many thanks!

error: the speech_to_text service returned an error. Error: No speech detected for 60s.

Large latancy about 7-9 seconds

Hi,

When i run conversation.js code all run correctly but i get big latency (in average 7 sec.). How can reduce the latency of TJBot?

Thanks.

Cannot find Module

I am having several problems with Errors when running the conversation.js and stt.js. In the instance below, the module that cannot be found is the 'rpi-gpio'. It would be so great if someone can help me to know how to reconnect or point to these modules. I have tried npm install -g. I have reinstalled everything from scratch and I still end up with these issues.

making the new workspace in IBM conversation service

hi everyone
i have design the new conversation using IBM conversation service for TJBOT but when i copy workspace id along with downloaded json file and replace the default one coming with TJ,it's doesn't work TJBOT experience time out error any suggestion.
and also how can i combine conversation code with sentiment code.
finale how can i make the TJBOT code to run the moment i turn on my Raspberry pi3 without executing the script manually in cmd.
i'm in need of the above information my-email addr: [email protected]

LED (Neopixel) missing diagram/documentation

Can you add a fritzing diagram to show the connection to the Neopixel LED? After some digging I found out the following:

RPI 5V -- diode -- LED V
RPI GND -- LED GND
RPI 18 -- LED Data In

Thanks!

tj.play() specifies plughw:0,0?? Can't hear TJBot voice with USB sound card

Everything is working, except TJBot voice is not heard. I have a USB sound card (plugable) with mic and speakers plugged in.

Edited /usr/share/alsa/alsa.conf to set defaults.ctl.card and defaults.pcm.card both equal to 1

speaker-test -c2 [success!]
arecord --format cd MicTest2.wav -V mono [success!]
aplay MicTest2.wav [success!]
sudo node test.speaker.js [fail - no sound heard]
aplay /usr/share/sounds/alsa/Front_Center.wav [success!]

noticed from verbose logging that tj.play() specifies device=plughw:0,0
my usb sound card is at plughw:1,0

can I get tj.play() to use plughw:1,0?

Tweets

After running "Sudo node sentiment.js",its showing

"Not enough tweets collected to perform sentiment analysis"

I tried changing the "exports.sentiment.keyword" but same issue persisted.

conversation.js Error: TJBot.prototype.pulseOnce = function(color, duration = 1.0)

13 days ago I posted on https://www.instructables.com/id/Build-a-Talking-Robot-With-Watson-and-Raspberry-Pi/ as AlanU7 but so far no response. I'll just summerise the issue here.

I followed all the build steps and when running conversation.js got the error: TJBot.prototype.pulseOnce = function(color, duration = 1.0)

Whilst that instructable does not include the LED the code seems to be trying to control the LED. I then followed the instructable "Build TJBot Out of Cardboard" at http://www.instructables.com/id/Use-Your-Voice-to-Control-a-Light-With-Watson/ which does have the LED but get the same error when running sudo test.led.js

Note: I responded to my own post on instructables twice but the order is:
original post
reply 2
reply 3

I'm trying to get TJBot working for a talk I'm giving on May 9 so help much appreciated.
Thanks
Alan
PS1 I'll be happy to not have the LED as I wish to demonstrate Watson's conversation prowess!
PS2 On https://learn.adafruit.com/adafruit-neopixel-uberguide/overview they say the NeoPixels are not suitable for Raspberry Pi. I can solder an ordinary RGB LED but I guess the code will need changing quite a bit.

Issues with Bluetooth Speaker when using TJBot tests and samples

Hello, I am having an issue on my TJBot (Ziggy) using my Bluetooth speaker with TJBot tests and samples.

Here are some details:

• The bluetooth speaker works for playing audio from TJBot without using TJBot samples or tests.
  -- aplay sample.wav works
  -- aplay -l lists no devices.
• The bluetooth speaker works using aplay -D default sample.wav
• The bluetooth speaker does not work using sudo aplay -D default sample.wav
• The bluetooth speaker does not work using aplay -D plughw:0,0 sample.wav (or 0,1, or 1,0, or 1,1) - This does not work with sudo either.
• I have copied the blacklist for the sound files to the proper location - if I don't have this copied over, my led light doesn't work properly.

Any help you can give is appreciated!

PS: here is a picture of Ziggy so you can see how adorable she is.

[rpi-ws281x-native] Could not verify raspberry-pi version.

Hi Team,

I am using speech to text recipe. When i try to use sudo node stt.js, I get the following error

[rpi-ws281x-native] Could not verify raspberry-pi version. If this is wrong and you are running this on a raspberry-pi, please file a bug-report at https://github.com/beyondscreen/node-rpi-ws281x-native/issues

I created new instance for credentials for speech to text & also deleted any old services.
Could you please help in this regard

Thanks

Sending custom variable to Conversation Editor

Hi all, appreciated the newer and cleaner code, quick question, with the old code (before March) I can create custom variables and sent them with input array directly in the .js file, and also receive them too. Where do I do that now? Or is it possible with the new code?

Clarify NeoPixel RGB LED size

I'm pretty sure the NeoPixel RGB LED should be 8mm (measured the hole on a 3D printed head, and that seems to be the size the instructables link to) however the links on in github take you to 5mm LEDs.

It would be great to update the link text to indicate the required size explicitly, and update the links to point to the correct size.

RPi is a tight fit when 3d printed

The clearance when inserting the Raspberry pi is too tight - I had to shave off quite a bit of plastic.

Change the language of the TJbot issue

HI, when we try change the language of TJbot on conversation.js

// set up TJBot's configuration
var tjConfig = {
log: {
level: 'verbose'
},
robot: {
gender: 'female',
name: 'Maria'
},
listen: {
language: 'pt-BR'
//language: 'en-US'
},
speak: {
language: 'pt-BR'
//language: 'en-US'
}
};

The TJbot is not recognizing the name when we set the language to pt-BR, but when we try do the same on en-US the change name works.

When we told the name of robot "Maria" and setup the language of en-US works, but when we set to pt-BR the tjbot not trigger any action.

TJbot is thinking - but not talking back to me

Dear all,

My TJbot hears what I say, but does not respond to me, either in the terminal or on audio. No errors are given either. The output looks as follows:

pi@TJbot:~/tjbot/recipes/conversation $ sudo node conversation.js
info: Hello from TJBot! My name is TJ.
You can ask me to introduce myself or tell you a joke.
Try saying, "TJ, please introduce yourself" or "TJ, who are you?"
You can also say, "TJ, tell me a joke!"

info: TJBot heard: I 
info: TJBot heard: TJ tell me a joke

  gain: 100,
  debug: true,
  player: 'aplay',
  device: 'plughw:0,0' }

At first I thought it was an audio problem, as I had found out through aplay that plughw needed to be 2,0 rather than 0,0. I have bought a standard ADAfruit TJbot package that contains a USB speaker and USB microphone. Testing both devices separately, they work fine. You can find the output from aplay and arecord below:

I tried changing the alsa.conf file, and when that didn't work I made sure the raspberry pi itself recognized my audio devices and set the USB speaker to default, I created an asound.conf file and I even adapted the conversation.js and sst.js files. See changes below:

Alsa.conf

defaults.pcm.card 2

defaults.pcm.subdevice -1
defaults.pcm.nonblock 1

}

Conversation.js & sst.js

// set up TJBot's configuration
var tjConfig = {
    verboseLogging: true,
    speakerDeviceId: 'plughw:2,0',
    microphoneDeviceId: 'plughw:1,0',
        robot: {
                name: 'TJ',
                homophones: ['DJ','Deejay','Teejay'],
                gender: 'female'
    }
};

I followed the tutorial of instructables when setting up TJ and also looked at the troubleshooting section:

If you see TJBot's response on the terminal but don't hear TJBot talking, there is a good chance that one of these two things has happened: (1) The audio output is directed to a wrong channel (you can fix it from raspi-config), (2) your sound modules are blocked. In that case, go to /etc/modprobe.d/ and remove blacklist-rgb-led.conf

Then run the following command:
sudo update-initramfs -u
Reboot and confirm the "snd" modules are running by executing the command "lsmod". This should solve the problem.
lsmod

The first option does not seem to apply to me since I have a USB speaker, no audio jack or HDMI. For the second option, I don't even have the file blacklist-rgb-led.conf. Since I tried most audio-related troubleshooting, I'm wondering whether it is something with TJ just not responding, but as far as I'm aware I have installed the Conversation, Speech-to-Text and Text-to-Speech correctly and my credentials have been correctly inserted. Can you please help me?

Continuous Conversation

Hi,

Would you please tell how to work with "continuous conversation" ?
I setup dialog with "continuous conversation", It seems can not go to second dialog.
I tested the dialog and it works on Web.

Please help.

Thank you.

speech_to_text no longer compiles

Hi - on Raspbian 4.1.18-v7+ (should be latest, just ran apt-get upgrade)

Can't hear my tjbot

I followed all the instructions and when i talk i can see in the terminal what i said (except the fact that if i say watson, the tjbot understand what song).
by the way, after i see what i said, nothing happened. the tjbot doesn't speak and no answers at all even as text. I checked if there was a problem with the audio, but if i go to youtube i can hear the sound without problem. Even testing the speakers it works, so i can't understand why i can't communicate with the tjbot. I made all the procedure 4 times from zero..... :( please help

Huge delay, is it normal??

There's a huge delay on listening. is it normal?
Works fine on nodered, manual command. TJBot doesn't

Conversation can only do 1 node

When I converse, I think watson goes back to the beginning of the node after it returns my first response when I have subsequent nodes waiting. I have tested the conversation dialog on IBM's website and it works fine

static sound from audio jack when LED is used

when LED is enabled, there will be static sounds coming from the audio jack (speaker). Seems like the PWD pin is conflicting with the audio jack. Please help to debug.

Error: TJBot is not configured to listen.

Hi, Here is the output when I tried conversation:
I tried to create the speech to txt service and copy password and username to config.js serveral time, but no luck.
But same credential works in the another speech to txt recipe. Any ideas?
By the way, in speech to txt recipe, the latency is so long, ~10s. I am in AU. Any reason? long distance?

Thank you very much!

I get the following error (below) when I try the conversation recipe.

Now, when I execute stt.js I get TJ is now listening and command line comes back immediately.
Any ideas?

Syntax error when running bootstrap

I ran the boostrap script on a freshinstall of rasbian and got the following errors

bash: line 169: syntax error near unexpected token 'fi'
bash: line 169: 'fi'

This is causing the script to end early and not completing the setup process.

Suggestion: use normal RGB LED

Since the https://github.com/victordibia/tjwave project is using pigpio to control the servo motor, why not also use it to PWM a bog-standard diffused RGB LED instead of the hard-to-get-hold-of (at least for me) neopixel RGB LED?

Jumps

Seem to be having issues with TJ Bot returning jumps. When I set up a jump without a condition, Conversation service doesn't return the next piece of content in the dialogue, even though the conversation works within the conversation service Work-space.

Two recipes repo

There is two recipes folders in ibmtjbot:

https://github.com/ibmtjbot/tjbot/tree/master/recipes
https://github.com/ibmtjbot/recipes

It is a little confuse. The code is different.

TJ gets tongue-tied when conversation response includes output text array with empty members

The output of the Conversation service includes a text array which can include empty text. When TJ encounters this kind of output and tries to send empty text to the text to speech service, it causes an error.

For example, the sample car workspace causes this issue.

Servo arm too far recessed => arm falls off

The Servo arm is recessed too far and so it doesn't clip well into the servo motor. This leads to the arm falling off easily.

Conversation payload quota

Hi,

I always got the following error message when using conversation.js, what does it mean ?

=== Watson Speech to Text : An Error has occurred =====
You may have exceeded your payload quota.
Error: Session closed. Reason: Payload exceeds the 104857600 bytes limit.
Press +C to exit.

Thank you.
