It assembles easily in a few hours. I would recommend this arm over any other robot arm for robot experimenters as it will last. I intended to write about it in my monthly column in a robotics magazine and was waiting for their version of the 5-DOF hands, another manufacturer's version of which is shown in the photo. I never received those hands from LeWanSoul. I did receive their X-Arm shown to the right in the photo and found it to also be of excellent quality. 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 desertcart 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. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B074T6DPKX | | Batteries Included | No | | Batteries Required? | No | | Customer Reviews | 4.2 4.2 out of 5 stars (283) | | Date First Available | September 20, 2017 | | Item model number | LeArm | | Material Type(s) | Metal | | Model Number | LeArm | | Number of Pieces | 1 | | Product Dimensions | 46.51 x 11.94 x 28.5 cm; 1.91 kg | | Target Gender | Unisex | ## Images ![LeArm 6DOF Full Metal Robotic Arm with Servo, Controller, Wireless Handle, Free PC Software and APP, Video Tutorials for Arduino Starter - Image 1](https://m.media-amazon.com/images/I/610tPYOvGHL.jpg) ![LeArm 6DOF Full Metal Robotic Arm with Servo, Controller, Wireless Handle, Free PC Software and APP, Video Tutorials for Arduino Starter - Image 2](https://m.media-amazon.com/images/I/71GDNzrn0-L.jpg) ![LeArm 6DOF Full Metal Robotic Arm with Servo, Controller, Wireless Handle, Free PC Software and APP, Video Tutorials for Arduino Starter - Image 3](https://m.media-amazon.com/images/I/71pKcGrmgbL.jpg) ![LeArm 6DOF Full Metal Robotic Arm with Servo, Controller, Wireless Handle, Free PC Software and APP, Video Tutorials for Arduino Starter - Image 4](https://m.media-amazon.com/images/I/61Jvu9yQe3L.jpg) ![LeArm 6DOF Full Metal Robotic Arm with Servo, Controller, Wireless Handle, Free PC Software and APP, Video Tutorials for Arduino Starter - Image 5](https://m.media-amazon.com/images/I/618fqVZBJwL.jpg) ## Questions & Answers **Q: Can you provide a functioning link for the pc software. all links i have are broken or redirected to bet365. please share if you have.** A: https://www.dropbox.com/sh/b3v81sb9nwir16q/AABvhlqYbOiuDhgOnAwqL_B1a/LeArm%20Robotic%20Arm?dl=0&subfolder_nav_tracking=1 **Q: how much weight can it lift?** A: About 250 grams. **Q: how far maximum range of wireless connection? lubrication is required ?** A: I have used at about 3m, no further.

I found the kit extremely well thought out. The parts machining and anodizing are just beautiful. A very important aspect of this design is the turntable that the arm sits on. It is built using a large diameter industrial quality bearing which provides a very solid base for the arm to operate on and provide servo-controlled rotation. The servos are top quality, very smooth operation and very powerful. The gripper is pre-assembled, a nice touch, and the joint design is quite clever. LewanSoul provides excellent tutorial videos, and an extremely helpful assembly video using 3D modeling to show how things go together in sequence. Another reviewer noted the importance of sorting out all the fastener hardware, that really helped smooth the build for me. The Bluetooth connection to the free iPhone app worked great, another impressive feature of this kit, especially for the money. The PS2 controller worked fine, though I prefer the iPhone app. There is also PC interface software that is provided although I have not tried that. I'm particularly interested in connecting an Arduino to the arm and writing sketches for controlling LeArm, and Aaron at LewanSoul showed me where to find the necessary information for that. LewanSoul has been very responsive answering my questions. Oh, and check out the video for LeHand on the LewanSoul website. ## Frequently Bought Together - Robotic Arm Kit 6DOF Programming Robot Arm with 5 Servo, Handle, Mechanical Claw and More, PC Software APP Control with Tutorial - ELEGOO 120pcs Multicolored Dupont Wire 40pin Male to Female, 40pin Male to Male, 40pin Female to Female Breadboard Jumper Ribbon Cables Kit Compatible with Arduino Projects - ELEGOO UNO R3 Smart Robot Car Kit V4 for Arduino Robotics for Kids Ages 8-12 12-16 STEM Science Kits Coding Gifts for 8 9 10 11 12 13 14 15 16 Year Old Boys Girls Teens Cool Engineering Building Toys --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/725736173-learm-6dof-full-metal-robotic-arm-with-servo-controller-wireless](https://www.desertcart.pt/products/725736173-learm-6dof-full-metal-robotic-arm-with-servo-controller-wireless) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-04-22*
