2 DOF Pan and Tilt with Mg995 Servos Sensor Mount for Arduino Robot Set Car Plane DIY

For the price of these you really can't go wrong. I received all the parts pictured, as well as some assorted generic servo parts that I assume just come with each servo when they sell the servos alone. The instructions are horrible, but if you can't figure out how to put this together without instructions then you probably shouldn't be messing with this sort of thing anyway. My parts were all metal (cheese grade, but metal). The servos work fine, they are 180 degree servos which I don't think it says anywhere. I had some issues initially with jitter etc but resolved that by finding a better power supply and making sure my grounds were good.

One liner: Can’t assemble with supplied screws. Look at the images in the product gallery. No screws installed. I just noticed. More things: cannot drive with 3.3v PWM. Ok, I can get around that. Motors are 360 degree. I thought 180 degree. That’s ok, I can get around that. I cannot get around the inability to assemble!!! Lack of instructions should have tipped me off but there is no way to make this work with what they supply. I’d rather pitch each component up in the air and slam it with a baseball bat! At least it would be fun. I read the reviews after with the same complaints. I normally don’t read reviews as I expect basic functionality but this is a complete joke. What’s worse is that the stupid supplier makes no attempt to correct it with the reviews saying the same stuff. Save your money and buy something better the first time. Ugh!!!!!

This pan-and-tilt kit works well for basic robotics and Arduino projects. The frame assembled easily, and the mounting holes lined up correctly for attaching sensors or small cameras. Movement on both axes was smooth once everything was tightened and centered. The MG995 servos provide enough torque for light payloads like ultrasonic sensors or small modules. Wiring was straightforward, and the servos responded normally when connected to a controller. Build quality is what you’d expect for hobby robotics—functional and suitable for experimentation. Overall, this is a useful 2-DOF mount for learning motion control, sensor tracking, or small robot builds. Best suited for DIY and educational projects rather than precision applications.

Generally these were exactly what I thought they were going to be. It helped that I has seen them before. The only reason I did not rate this as a 5 start is that the assembly instructions were really more vague than I wanted. I gave these to my 13 year old son to assemble and I was working on some software to drive them using a Synapse Wireless product. He was not able to figure it all out with out help. The pictures do show the proper connection, but some thought has to be put in as to what component to install first in a couple cases. Generally I am going to use part of the kit and the servos for projects so in the end the assembly instructions will not really matter. Good product overall.

These assemble fine and work great. They feel very sturdy. However, the current draw on these seems to be insane. I have not gotten around to measuring yet, but I was definitely having power problems running on an Arduino with it constantly resetting. At first, I tried running off USB power. Was not a huge surprise that did not work, and that wasn't a huge deal. I then wired them into a wallwart I had. Whenever they ran, the indicator light on the wart would dim the Arduino would reset. I tried a few warts I had (they were all the same brand/model), the same problem. Eventually, I used my benchtop power supply and was able to get it working right. It's possible that the problem is with the wallwarts and they aren't capable of delivering the current they claim. I have not had a problem with them in the past, but I got them cheap when outfitting my lab (I am a teacher), and I've had them work with other servos. The three stars are basically because I feel that I should be able to run a project off standard power supplies without too much of a hassle. I'm going to investigate more, but have been busy with the start of the school year. If it turns out the warts are the issue, I missed something, or I am derping something else up, I am going to update my review.

Easy to assemble, but had change screws. Those were included appeared to long. I used M3x6.

The brackets are well made, so a high score for that if it wasn't for the fact that they sent the wrong hardware. The machine screws for the servo circular horns are too long, they will not work! Plus there is so much additional hardware supplied it's hard to figure what to use. I really think they sent the wrong hardware package with the kit. I had to use my own hardware to assemble the kit. The first picture shows how the screws are too long, the other two show all the hardware supplied. Looks like I have a lot of surplus screws for new projects!

Mine was different from the picture. The coupling attached to the servos is plastic instead of metal. I'll probably need glue. No instructions, but it was fun to figure-out. I bought it for the gimbal. The legit servos make this a very good deal. Runs on Arduino Uno with some 470 microfarad capacitors placed in parallel with the servos.

4 years later and the screws lengths are still wrong. I should have listened to the negative reviews.
