There was a problem filtering reviews right now. Please try again later.
However, after a year of experimentation and demonstrations for others, I have found both of these robot arms far higher quality than any of the other robot arm kits is have tested. The LeArm uses separate 'standard' servos, each of which must be connected to a controller or Raspberry Pi or Arduino board. Depending on the position of the arm, I could manipulate almost a pound. Programming of the LeArm is fairly simple as you are dealing with standard servos that require basic pulse-width signal inputs.
The X-Arm has very similar construction but you can look at both robot arms at the Amazon site and see the physical similarities and differences in the two arms. Both use the same quality ball bearing base, though the metal structure is a bit different and the gripper/claw is identical to the other. This arm uses their LX-15D intelligent serial bus servos that can be 'daisy-chained' and the final end of the three wires of the daisy chain transfers the servo's address (each servo has a number of 1 to 6) and power through the three wires. (You can see the small connector on the end of the white cable in my photo) Your microcontroller addresses each servo independently through that cable, very similar to the Robotis Dynamixel servos. The higher cost is due to the cost of the high-cost intelligent servos.
I had a bit of trouble programming the arm with a RaspberryPi but soon got the hang of it. I ended up writing a bit of code to use it with Python, directly.
The only issue I might say is using the tiny metric screws that were all in one bag. I found some that were too long so I used washers in mounting them to the small aluminum cylinders between the servos. One of the threaded holes in the long cylinder was a few degrees off 90 degrees so I just left the screw off. The video instructions were fine though I would have preferred a written manual. I found myself 'rewinding' the video to listen again 'what the girl really said.' I also would have liked to test their two hand models as theirs seems so much better made than the other company's hands shown in my photo.
I also have their 6, 16, 24 and 32 channel servo controllers that have extensively come into use with my demonstrations. The LSC-6 controller is furnished with the LeArm and is used with the hand controller (they call it a "handle") to control the arm wirelessly. Note the receiver board in the photo of their photo of the arm.
I would highly recommend the LewanSoul robotic arms and controllers and servo testers for students from high school to advanced university instruction, as well as home experimenters. Either of their servo models are well made with metal gears and have yet to fail for me. Their web site offers much material on their products, and they have been around long enough for one to find all sorts of articles about uses of the LewanSoul robot arms and controllers.

I wish there was an interface to program against using the USB port. The serial port is documented and should provide a good interface.
The assembly is a little unclear at several points but I was able deal with it once I got it assembled. A couple of the screws seem to interfere with the mounting bracket and the servo. Fortunately, I had some washers and worked around the issue.
One servos connector was pinched a little, making it difficult to get the cable plugged in. The other similar servos connector was tight but not pinched. This was simply an inconvenience.
I initially put the arm together as exactly as I could, following the instruction video. Here there was one real problem making assembly impossible. At the point of installing the servo that turns the wrist there was not enough room. I had to lift the servo by putting an additional layer of nuts between the servo ears and the aluminum bracket. This meant I had to replace the supplied screws ones with 4 that were about 3 mm longer (the thickness of the extra nut, and turn the screws around so the head is below the bracket and the nut is on top of the servo ear
The info on what connects where was unclear. It took some experimentation to get everything connected properly and working, and again, this was simply an inconvenience, not a real problem.
At this point everything is working with the included controller and remote.
Now for the second design issue. I replaced the controller and began developing my own software. This was going well until the gripper fell off. The problem was the plastic shaft on the wrist servo supporting the entire weight of the gripper assembly. The screw into the servos shaft pulled out taking pieces of the shaft plastic with it. I will have to replace this servo with a metal shafted one using a metal connector plate. I do not hold the manufacturer responsible for this failure directly because my software had been abusing the assembly a little. But they should reconsider the use of the tiny plastic connection between these two parts.
Update:
I set all the servos except the gripper cycling from 500us to 2500us letting it sit for a few seconds at each extreme. It did this flawlessly for about 1-2 hours, then something went wrong in at least one servo. The base stopped rotating correctly and I think one of the arm servos is also misbehaving. I'll have to take it all apart and test each servo in detail to discover exactly what went wrong.
With the original issues and now this short lived failure, I'm taking another star. At this point this kit is nothing more than a starting point for upgrades and improvement. Will update again once I get more information on the failure.
Final Update:
After checking things out, It looks like there was something going on with the base servo, but it has resolved itself. I resolved the wrist servo issue with a much longer screw - it seems that the one supplied was barely connecting.
So after re-assembling completely, I'm happy to say everything is working perfectly, but this only happened after traveling a somewhat bumpy road.
