Im researching servo's for my inmoov, and came across the serial servos by dynamixel and the more affordable alternatives by lobot (and?) lewansoul.
First of all Im confused, is lobot a knock-off of lewansoul or are they the same and perhaps a new brand name for lewansoul?
Does anyone have experience with these servos (the bigger, serial ones) ? How do they cope with heavy loads, how is their speed/accuracy, backlash and noise?
And last, but not least, I see the lewansoul servos are supported by a EZB plugin, which is fantastic. But is there also support to read parameters back from the servo, like temperature and position? This could be super useful, allowing you to position your robot by hand and then just record those positions.
Likewise, I assume there is no support for changing the PIDs and changing mode from 270 degree to continuous rotation etc?

and this for the lewansoul you can use a board like this also has built in memory for playback of stored animations

That said, the videos Ive seen of Alan do showcase the quality of the dynamixel servos, they are fast, seem to have little to no backlash and are especially surprisingly quiet, and noise is one reason Id like to use something else than hobbyking or similar RC servos. Of course, the dynamixels also cost an arm and a leg (I guess thats why Alan doesnt have any :p) . You wouldnt happen to know how the lewansouls compare, have you tried them?
As for the plug in, absolutely the way to go would be to be have a way to monitor directly in ARC. I'm not sure but maybe its a communication thing..ie the plug in can write out to tell the servo where to go, but any returned info dealing with temp and torque etc must be ignore or unable to be retrieve by the EZB.
Dynamixels are stupidly expensive. And they keep making more so someone is buying them. They did release a new model that is the size of a standard servo and cost 49 USD but I cannot get them to work with the Dynamixel plug in.
Anyway, Ill just buy a few and try. I wont be able to compare to a dynamixel, but at least I can see how it works and maybe even try to modify the plugin code to read back data.

Both Nink and DJ lambaste these servos and DJ stated no further development will done on the plugin because the servos arent worth it.
Thats a bummer. And possibly a premature conclusion, if no attempts where made to set parameters like speed and PIDs.
