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

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

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.

A horrible kit. Instructions are worthless

Fast Delivery and well packaged. I would buy from you guys again. I wish that instructions were clearer.

some metallic rings were missingI had to use diy stuff I had at home to be able to mount this armconfusing 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.

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.

On Time!!
