Bioloid Vision Module

[nyoo offline]

after some advise from anyone who answer my questions, finally i can test and calibrate HaViMo 2 with some objects, using USB2Dynamixel.....but my next question is, after calibrating HaViMo 2 with some objects (field, ball, etc) how can i call those object that i have calibrated with roboplus???

btw thx for sending me an example to program HaViMo 2 with CM-5...

hi everyone,
btw do anyone know how to display the output value (ex: index, colors, pixel, MaxX, MaxY, etc) of the objects that have been calibrated (using program provided in this forum) by havimo 2???

and, do anyone know how to use the file "camerareg15.txt" that is made by havimo color calibration program???

btw, i want to program my robot with that sensor using roboplus...


thx 4 answering

Hi nyoo,

hi everyone,
btw do anyone know how to display the output value (ex: index, colors, pixel, MaxX, MaxY, etc) of the objects that have been calibrated (using program provided in this forum) by havimo 2???

I've only been using one index colour so far (tracking a single red ball), but for the bounding box data (the sample code returns the largest one found for a given index colour) I just added some print statements into the Task script.

and, do anyone know how to use the file "camerareg15.txt" that is made by havimo color calibration program???

btw, i want to program my robot with that sensor using roboplus...

I think this is just a quick way to dump out all the register settings in one go so you can more easily examine them when fine-tuning the camera to your needs (need to reference the camera spec sheet to get all the gruesome details about which registers do what). For example I was certainly tweaking things to try and improve sensitivity in low light conditions, though brighter room lighting would be a more reliable solution I'm not sure if you can re-import that text file, I was just tweaking individual registers one at a time and testing the results.

Gary, you say you can display the output value of that camera...do you have some examples related with it anyway??? actually i just want it to program my CM-5 using roboplus so that it can track the object ....

btw, do anyone know how to display the output data format (ex :pixel, min X, max X, etc) of havimo 2 if i use USB2Dynamixel to connect it with PC???

hello?? anyone??

Here's a ziped RoboPlus Task file showing a very simple HaViMo2 pan and tilt setup for looking towards the colour defined in palette 1 (I stripped down the camera2.tsk file provided by hamid_m and tinkered with it on a CM-510). Servo ID 19 was pan and ID 20 was tilt. It prints out a few values I was using for debugging. 1) Camera address [*] 2) Bounding box Max size (I was tinkering with the idea of ignoring values below a certain size) 3) the bounding box x centroid 4) the bounding box y centroid. Hope it's of some use:

[*] if you loop the script too fast (see the WAIT WHILE time loop of 0.256sec), the camera returns errors rather than data, I was using this camera address read as minimal test case while tweaking the delay.

where is the output data of the object printed anyway?? robot terminal or havimo software, or?

I use RoboPlus Task, when you download a script to the robot the 'download complete' dialogue has two buttons, one is OK, the other is show output. There is also a show output icon in the toolbar. Just make sure you have the window open first, and leave the serial cable connected, before you run the program on the robot. If you're still stuck have a look at the RoboPlus Task help/manual, pretty sure the first example code it gives is how to write a script that just prints Hello World to the output.

wew, thanks for your advice!!!
finally i can operate it well, although it can only do pan and tilt!!
but there is still problem left for me.... when i try to program it to track a ball using roboplus, the camera won't work if its function for initializing is not called, unlike AX-S1 that can work without getting interrupted by other functions...it is really hard to make the robot arrange its position towards the ball...btw how can i make the camera work like that??

thx for answering

[nyoo offline]

hello,
thx for every advice that is given to me in this forum till i can make it work and i can use it to track a ball, but now i get some different trouble with my havimo....

when i try to connect my havimo again (by using the same way that works well on my havimo ) i see on the havimo calibration program that my camera is not found.....but, before that problem occured, my havimo worked very well...and also i found no problem on my usb2dynamixel because it could be used to connect to other robotis devices...... btw, what is the problem that occurs on my havimo now actually????

thx 4 answering

*btw, if you don't mind, please answer my question above this post :p*

Hi, we are working with the Havimo 1.5 and with the CM-510, we know the example is for CM-5 somebody change the example to work with the CM-510 ? or which are the main differences between both modules ?
Thanks !.

Hi. The script works fine on the CM-510 (that's what I was using here), but I'm not sure that the HaViMo1.5 will work with it. Pretty sure the HaViMo2 was the first version to work with RoboPlus Task (I waited for the HaViMo v2.0 release for just this feature).

What can you tell me how to do work with two colors or more

[hamid_m offline]

Hi everyone,

before I go to my vacations, I would like to announce the code release of the new calibration program for the HaViMo:

https://sourceforge.net/projects/havimo/

The new client program is a port of the old one into Qt. Some additional features are included:

- camera parameters are now named and can be set with sliders and check boxes.
- parameters are read life from the camera, which is good for using auto exposure and auto white balance.

The program still supports only USB2Dynamixel, but as the next development step I will add an in system support of the module via CM5/510 or robobuilder RBC.


If any developers are interested in collaborating simply write me.

I would be glad to hear your feedback, and more glad if some of you can help me in the development.

Best regards,
Hamid.

Hi everyone,

I'm now back from vacations.
I worked a little bit more on the code and now following is available:

- Calibration and preview of the results using USB2Dynamixel
- Calibration and preview of the results using CM5 (in system calibration)
- Calibration and preview of the results using CM510 (in system calibration)

there is still some communication problems when reading the look up table back in CM5 and CM510 modes.

I also uploaded the binaries for windows, so everyone can easily download and test the program.

Best regards,
Hamid.
