I would like to get some help on serial bus servo's that use almost the same protocol as dynamixel.

BUT all the dynamixel instruction packets and status packets start with:

0xFF 0xFF and then you get ID> Length> Instruction>Parameters>Checksum

like this

The servo's I want to use are Lobot LX-16A that use the same protocol with one difference: the packets start with 0x55 0x55 and then ID> Length> Instruction>Parameters>Checksum

so my servo's don't react on the dynamixelplugin
How can I or someone change the 0xff too 0x55 in the plugin?
Is it possible too get the source code for the plugin?
or is there another solution?
I can't afford real dynamixels and this seemed a good alternative


thanx in advance for your help

I have found a few conversations, tutorials and activities that may help with your question. Take a look at these links. I've sorted them by what I believe to be most relevant but that is not always the case as I'm still learning.


Also, consider reviewing the Learn section for informative lessons and activities. Check it out!

Hmm, the plugin description indicates it is open source, so you should be able to modify it, but if there is a link to the source code, I am missing it (other open source plugins have a link in the description).

@DJ is this one open source and am I right that the link is missing?

Thank you for this fast response techguru and DJ Sures

I hope that I can get this to work will take some time but if I got it working i will post it for other people too use.

I think these are nice servo's and it will open some new possibilities for my Ez robot
Can tell you that I'm very happy with Ez robot and the effort that is put in it.

thanks guys
