Much stronger than other arms I have put together before

You must keep in mind this is an educational robotic arm. Don't expect it to lift and move very much. I had to beef up the base platforms by inserting spacers to form them up, also on the vertical platform mount for the shoulder servo mount. Also, as seen on youtube videos, added a support under the c channel for the base pivot. Without these extra stiffening methods the arm is unstable and can get into oscillating movement. As far as parts go, only thing missing were screws and nuts to mount the servos. Fortunately I had some on hand. As others mentioned, this arm needs to be mounted to a base platform of some sort, I used a board roughly 11" x 11". Lastly, I'm using an arduino mega board with a PCA9685 to drive the arm. Also have a micro sd module to enable recording and playback capability. The arm has worked well during my programming activity, but I just had a servo fail. The weight of the arm with servos just about maxes out the capability of the shoulder joint, one with more torque capability would be better. I will replace the servo with a more powerful one. With all that said, I'm still not sorry I purchased this arm as my objective is to experiment with the arduino and programming.

The channels and servo supports are solid, but with the weight of the slightly sloppy gripper, they overwhelm the holding power of the servos. No instructions are included, and sticker was applied over the image on the box.

I've got a 15amp power supply power these little servos and the weight of the arm is still too much. The robots arms keep falling or jerking whenever it moves no matter how long I set the delay to. It'd be an amazing kit if it had some stronger servos but I don't know these devices well enough yet to go through and upgrade the primary axis for arm locomotion to a servo that would still fit in the space provided.

Nice product, its sturdy and easy to assemble, the servos are cheap quality, but works just fine... I purchased 4 more servos because one of the servos didn't handled all the weight of the arm and died on me, but I think it was an abnormal case, my friend also bought one and his is just fine

This robot arm came with no instructions on how to put it together. I was only as able to find one video on YouTube and the guy showing how to put it together messed up on the build and then had the viewers go back with him to correct his mistake. And the guy also whispered really weird the whole video like he was tryin to make it an ASMR. Please include instructions or at least a qr code for a link to some instructions.

The media could not be loaded. Great arm for my project in the video is result.

Here’s the kit as I assembled it. It was reasonably straightforward although the instructions were incomprehensible in places. I mostly relied on the pictures after the first few steps.The jumble of wires is an Arduino Uno microcontroller that I programmed to control the arm via the three joysticks in the foreground. The programming was pretty simple although I made the initial mistake of using the joystick inputs as the absolute position instead of incremental values. The joysticks are available from Amazon. Beware that you need to stow the arm away in a stable position before powering down — otherwise the arm collapses in a heap.Probably not a beginner project.
