Robotic Arm Kit Silver ROT3U 6DOF Aluminium Robot Arm Mechanical Robotic Clamp Claw Kits No Soldering Required (Unassembled Parts Without Servos)

Super easy to assemble. I found some directions online, but you can get where you need to be by looking at the picture. Fits my servos like a glove. My shoulder servo lifts the arm just fine. Still need to test how much it can pick up. Sturdy. Shouldn't write reviews first thing in the morning....

Inventory of screws is inaccurate. Key steps are merely alluded to in pictures. Otherwise seems a decent kit for the price if you want to choose stronger servos but don't want to source all the other parts individually.

some metallic rings were missing I had to use diy stuff I had at home to be able to mount this arm confusing instructions....

This robot arm is great for the hobbyist or DIY student. I can use mine with 3 - 4 AA battery packs or a variable power supply. I have used the arm with a micro-controller and written a controller program with Tkinter. I have read someone complain about the servo movement being jerky. That will not happen if you use small increments in the degrees. I increment the servos in 5 degree steps. But if you want finer accuracy you can use 1 or 3 degrees. 10 degrees at a time will give faster movement. I am working on a program for have the robot arm move player pieces for playing tic tac toe and chess. Worth the money and time to build if you are interested in learning about robotics.

Terrible. Never mentioned that we also had to get servo disc headers. Save your time and just buy a full kit.

The arm was fairly easy to put together. They provided more nuts/bolts than were needed. I used 5 mg995 servos and one heavy duty ezrobot servo for the 2nd position up from the bottom. The arm gets heavy with all the servos and an mg995 won't lift it. This was a fun little project.

Good product. The only problem I have is that it doesn't get sent with an instruction book, but instead you need to request one from the seller. Also please start labeling the screws. PLEASE!!!

It took sometimes to put it together based on pictures. But this should be nothing if u are already cane to this level. One thing, it ONLY comes metal pieces. U need to buy sevor,board....etc

Il manque les six moteurs et des pièces.
