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 dunno if i trust that company - they haven't paid for an SSL certificate for almost 2 years.

The Robotshop carries their stock, so someone is communicating and ordering from them. Somewhat legit.

Just a suggestion. They are pretty impressive and are TTL...

Been looking into these servos a bit more in depth. They have an enormous amount of torque which i like for some of my upcoming big projects. Another thing I like is they have a programmable ease in and ease out, which is great for natural motion.

It looks like there are 4 wires power, ground, and tx/rx. I'm going to order one of their servos and the programmer and do some dynamixel comparisons. 

As always the manual is lacking...like there is no manual at all, so will have to test some of the other features on their programmer to better understand their function.
