(Lx-16a) - LewanSoul LX-16A Full Metal Gear Serial Bus Servo Robotic Servo with 17kg High Torque, Real-Time Feedback, Dual Ball Bearing for RC Robot Arm(Control Angle 240)

I ordered one of these along with the debug board to try these out. So far I am pleased. The servo has been easy to control using an Arduino and/or the accompanying software that lets you control the servo from a windows computer. You can control position and velocity, although the top rotational speed isn't very fast. This is a high torque, not an especially high speed servo. There is very little information easily available about this servo or how to control it when you open the box there is a link directing you to a dropbox folder that has software and pdf downloads that give more detailed, though not completely comprehensive information. The position of the servo can be read anywhere, even outside of the commendable position control mode. I'm planning on attempting to put together a robot manipulator that uses velocity control, so at some point in the future I'll be able to say how well the servo works in a real application. The case is sturdy plastic, and there are a couple of cheap features, but I fee that this is justified by the very low price compared to other servos with similar features. The only comparable servos that I know of are Dynamixel servos that cost at least 3x as much, but I haven't worked with those so I can't really say anything to compare quality or performance.Notes:Unless you really know what you are doing you need the associated debug board to make this work. You only need one board for several servos though. The servo gear is 25 tooth and fits some standard size Futaba parts that I had lying around. The servo gear screw is a M3 screw, and the screws that hold other parts onto the servo are M2.

My first application with these babies was a water valve control which needed precise positioning and durability. I first tried with similarly torqued 15KG.cm hobby servos at around the same price but found them to be strong but terribly imprecise. But since I wanted positional feedback I tried to make my own servo using a different gearbox/motor and adding positional encoders. While that worked it ended up being more expensive than I'd like since I need a bunch of these.Enter robot servos: These LX16A servos were my first venture into robot servos since the Dynamixels are way too pricey for the torque my application needs. And I must say these servos are superb. Strong torque, internals are well made especially the rotary pot encode is much better quality than the similarly priced hobby servos have. And best of all these have positional/temperature feedback along with bunch of other things. I wrote my own driver in Python just by following the datasheet and everything worked great except for a couple of mistakes in the datasheet but hardly a problem. At this price I can honestly say I'm done with those hobby servos and their primitive PWM signal based positioning, yey!

Is a great product, but I needed more information that the one available. Beside that works awesome.
