Ezb 4 Controller Help

Question

To tech support the ezb4 controller voice is not on only I see a blinking light what can I do?

Steve G · Answer

@jerseylance. A couple of things to check first... 1) Is the battery that is powering the EZ-B fully charged? If the battery voltage is too low, it won't speak. 2) Can you connect the EZ-B to ARC (solid blue, or solid green LED will be seen depending on what WiFi mode you're in when it's connected)? If it does connect, do you hear anything, such as an audio tone? 3) If the above two points have been ruled out (Battery is fully charged, and the EZ-B is connected the ARC), then click on the the link I have provided below, as it may be of help to you... No sound from EZ-B and a link to a detailed and excellent tutorial about connecting and using the EZ-B v4... EZ-B v4 tutorial

I've tried everything but nothing doing, so what else can I do?

Steve G · Answer

Please answer this question first. Does your EZ-B connect to ARC on your computer? Do you get a solid blue or green light on the EZ-B? If it does and you have no sound, one possible cause could be a faulty speaker. If you are unable to connect your EZ-B to ARC on your PC, and you are hearing no noise whatsoever, it could be that the main processor could be faulty. I would suggest to use the "Contact Us" link and make a warrenty claim. When you are writing out the warrenty claim, make a reference to this this thread. But answer my questions first before you do. It might be worth your while completing more of the tutorials in the learn section, as from your profile, I see that you have only completed one lesson for the mobile app. I highly advise you read and mark these lessons as they will help you out a lot with your EZ-Robot products.

@jerseylance - It's really hard to help you when you are not giving much information to go on. It would be helpful to the community if you could list out what troubleshooting steps you have taken.

Ok Zap or the community my controller was working unto last week when I would start it up. It would have a blinking light green then blue no sound. I've read and done the things that the forum would tell me but no sound or connection to the web.

Steve G · Answer

Okay that's cleared things up a little bit more. I assume by "no connection to the web" you actually mean no connection between your EZ-B and ARC. Is that correct? If so, then it did work and had sound and did connect to ARC via AP mode (solid blue LED, not flashing) up until last week, but now it doesn't do either. Then it could be the ARM processor on the bottom board of your EZ-B is damaged. There was someone with a similar symptoms recently which was talked about in another thread. As this could be the case, read my post above about possible warrenty claim. EDIT:  Below is the link to the other thread I was talking about... EZ-B v4 broken. Please help.

DJ Sures · Answer

From your previous posts, it appears that you are attempting to use the ezb on a bioloid robot. Can you please share your electrical schematic and information how the ezb is powered? Circuits (pcbs) are fragile with incorrect electrical current configuration. Let us know the electrical schematic so we can identify the cause of how the controller was damaged and help prevent it from happening again.

Jerseylance · Answer

The EZB is supreme to none but I would like it to work with the JD head which I think is awsume. The ezb4 is what I was going to show my class how the robot can interact with facial and color.

Steve G · Answer

What did you have connected to your EZ-B before it stopped working? And as DJ asked, what power source was you using?

Jerseylance · Answer

The wire that is for the EZB which was not connected to nothing. The bioloid has its own controller which is no EZB do it would be use by itself.

Steve G · Answer

Quote:The wire that is for the EZB which was not connected to nothing Can you explain what "wire" you mean? I'm not sure what you mean by this.

Jerseylance · Answer

The camera from DJ's head...

Dunning-Kruger · Answer

@Jerseylance For a teacher (and no offence but) you are kind of cryptic and not very forthcoming with information... What courses do you teach?

Jerseylance · Answer

Art...

Steve G · Answer

So The only thing you have ever connected to your EZ-B is the camera a JD head, and nothing else? And you still haven't answered the question on what power source you are using to power the EZ-B? Is it a battery? What type is it, (LiPo, Nimh, ect)? What voltage is it? Are you using a power adapter? What type of adapter? These are quite an important questions for you to answer to help us help you. You say that you are a future robotics student in another thread. If this is the case, then you need to learn to offer much more information and details when trying to troubleshoot problems and answering questions, otherwise you will struggle to learn what you need. Like @Richard said, you are not very forth coming with information which is making it hard to help you.

UL class 2 power supply...

Steve G · Answer

Okay... What voltage is the class 2 giving the EZ-B? How many amps is the class 2 power supply supplying to the EZ-B?

Jerseylance · Answer

Sorry about that I'm getting ready for work but the power supply input 120vac 60hz 14w Output 9vdc 800mA

Dunning-Kruger · Answer

Hmmm.... 800mah may not be enough... especially since power supply manufacturers have a habit of over estimating their output....

Steve G · Answer

Agreed. 800mah may be a problem. Could you beg, borrow, but not steal another power supply to try to eliminate power as a problem? Something with at least 2 or 3 amp output, and over 6 volts. A LiPo or Nimh battery pack would be ideal to test this.

Jerseylance · Answer

Ok thanks I'm going buy one this week sorry not being more specific..

Steve G · Answer

Alright then. Get yourself a 7.4 v LiPo battery or a 7.2 NiMH battery pack with at least 1000mah and try again, and report back with your results. Good luck.

Dunning-Kruger · Answer

@Steve G.... the battery capacity doesn't really matter that much... what's important is the amount of current it can provide... The LIPOs that power the ez robot are only 1300 mah, but can provide a crap load of current...

Steve G · Answer

@Richard. I know, and fair point. I just didn't want him running out and getting something that will only last a few minutes before recharging. A 1000mah pack is pretty cheap and should get a reasonable run time. EDIT: And I see your point now. I added too many zeros. Should have read 1000 and not 10.000 mah. Oops. blush
