Bioloid Vision Module
Havimo 1.5/2 - observation/question

Hi Hamid,
I just got the new Havimo (altho the label on the ziplock bag said havimo 1, just inventory typo I'm sure).
I have one observation which may be unrealistic but I must ask. As the Havimo board rests on a plastic plate the chips generate alot of heat that I can feel on both the Havimo versions, my question is there a need for it to be so close to the plastic or can we cut a slot out so the chips can dissipate heat better? Does this add value. I'm thinking for prolonged use I don't want to overheat the circuit where I can avoid.
Cheers
Mark

Sorry for my late reply. Surprisingly I have received no notification that there are new posts in the forum, although I was watching it. I just got informed from Limor as I was fully busy with my team in Robocup German open competitions and this delayed everything for another week.
so far I have sent replies to Renaud and Alejandro. I am wondering if there are also other people having problems with the modules, and if yes, would they please inform me?

Hi Hamid,
I bought your vision module (v1.0) some months ago and had it working fine. Then a few weeks ago I mistakenly issued a reset command to it and I haven't been able to make it work since. It doesn't even show up when scanning for connected IDs.
Tangent question : Does the CM5 think of the vision module as an AX-12 or an AX-S1? I only ask this because the manual says the CM5 can handle 28 (or 30 depending on the manual) AX-12s and 10 AX-S1s.
Is it possible that issuing a reset command from the CM5 can stop the vision module from working? If so, how can I fix it? XTinX had mentioned the same problem, but bought a new vision module so there was no real troubleshooting of this problem.
Any help would be greatly appreciated.
Cheers!

Hi kamondelious,
The Module does not have any reset command. It means any such command sent to it is ignored. So the problem is not located there.
when the CM5 does not recognize the ID, This means that either there is a defect in power (check if the regulator has the 5v output and the micro controller has 2.8v), or there are some problems with the buffer (74126).
If you cannot locate and remove the problem, please contact me.
Best regards,
Hamid.

I dont have a robot and i have never built one but i am thinking about getting a bioloid comprehensive kit. I also want to get a HaViMo vision module but i want to know if it comes with the camera and if it is easy to setup. I have never used C and stuff like that either.
HaViMo Calibration using USB2Dynamixel

Hi everybody,
Having a long long discussion with Pedro, we have decided to write a version of the calibration program which does not need the CM5. It connects to the HaViMo through USB2Dynamixel. I am now working on increasing the download speed and even make it possible to have a stream.
This is the link to download the Application:

I'd be glad to here your feed back.
Best regards,
Hamid.

Great news Hamid 
I do love the fact that you can calibrate it without the need to change the firmware on the CM5.
Very very cool. Just plug into the PC calibrate it and connect it back to the Bioloid.
No need for firmware changes means much greater ease of use and I'm sure many other (novice) users will be attracted to it.
I think the next thing we'll be waiting for are the nice little software improvements we've discussed "HaViMo+Roboplus" (details on that are still a secret lol )

Hi Stuart
It seems we're fighting for Hamid's attention
He's "secretly" working on a Roboplus routine to use HaViMo with Roboplus per my request
He's already released the calibration software to work with USB2Dynamixel which - I must say - is a GREAT new feature.
In the old days you had to replace the firmware on the CM5 with the calibration firmware, run the calibration software, and restore the original firmware.
You'd have to do this whenever lighting conditions changed or you adjusted the colours to look for.
Now with the great new software working over USB2Dynamixel you just need to plug the camera to the USB2Dyn, calibrate and you're good to go.
However it is really really cool that the interest in HaViMo is picking up.
The module is amazing to me.

Hi Stuart,
yes, I'd be glad to. Let me see what is going on in the topic.

Also, I have posted an example program in C which makes a pan/tilt mechanism track a red ball. I think, all the needed functions can be found there,
We need a new class(or header). From the structure, it is similar to Dynamixel.h/.c but needs some minimal changes. For example to send the capture command to the camera, or to read/write filter values.
As also Pedro pointed out, there is no more need to implement the calibration interface as is it now possible through USB.
I will also send a reply on the libbioloid topic and tell others that I am ready to assist.
Best regards,
Hamid.
