    My 7 yr old daughter built this in about 8-9 hours. Supervision all throughout is required as parts need to be cleaned from excess plastic, and tightened properly. Some parts will need to be positioned precisely (like the clamp module). The quality of the plastic is quite good. It is similar to plastic model toys. While building, test the motors with a pair of wires to a battery if they can turn the gears properly before closing them in their housing. One electric motor failed to even work out of the box, so to make it work, I had to open it up and reposition the rotor and clean the contacts. My daughter now has some exposure of how those gears work to move something. She got to use a screwdriver, cutter, pliers, a digital multimeter in this exercise. I think she is no longer afraid of wires, since she tested all the motors before installing them. she now wants a butterfly robot. She also now want something that allows the arm to be mobile rather than be in a fixed base (I am thinking Revell Vexplorer). She plays with it by getting pencils from a case. Great weekend activity, quite educational, even for a 42 yr old. Very good value for the money.

    So, I got this for my 15 year old brother for his birthday. He’s all the time tinkering with things like broken VCRs and CD players and such, so I figured this would be perfect.

    It shipped fast and very well packaged. When my brother finally got it, it took him all of 45 minutes to have it put together. He loves it, he’s currently ‘teaching it how to write’ with a sharpie! It’s very easy to control and seems very sturdy, it’s not too big but it’s heavier than it looks. Overall, this was a fabulous gift and my brother was thrilled with it. It shouldn’t be too much of a challenge for anyone with a little electronics know-how (though it does have some pretty small parts you need to keep an eye on) and it’s a blast to play with!

    I was a little worry after reading all the reviews here, but decided to get one anyway. I purchased this robotic arms in hopes of learning more about how it’s made and perhaps one day make my own with servos. You do have to assemble it, but it’s not as hard as some people here claim. I’m not a patient person and it took me probably 2 hours, but I was going very slowly and taking greatest care of not to break any part. While it’s all made out of plastic it doesn’t really feel cheap. I found using small cutters best for detaching plastic parts. Just follow instructions in the book to the letter and you’ll be fine! I did make a number of mistakes assembling it and nearly broke gripper. Gripper is the hardest part and manual doesn’t mention that long screws are not suppose to be tight (they don’t go all the way in) so I stripped two of them 🙁 Another gotcha is size of some screws. They are extremely close in size to each other and I accidentally used wrong screws in couple of places but then realized and redid some parts. Forgot to install washers too, so had to remove and reattach base 🙂
    First thing I noticed right away is how small arm actually is. In the videos I’ve seen I thought it will be bigger, but it really is a toy size. Another small complaint is battery compartment. Once you close it, it will be hard to replace batteries later on. They should’ve made an opening at the end for batteries.
    Be aware that this arm doesn’t have any sensors, so you can break it if you push it beyond it’s range of motion. You’ll be hearing a lot of nasty clicks but so far I didn’t break it. Gripper is actually surprisingly strong and can lift things like a big screwdriver.
    Another thing I wish is for another degree of monition – gripper rotation. They way it’s now you can only pick up objects that are perpendicular to the base.
    I would be fun to modify robotic arm with Arduino. Right now there are no real electronic components (other than motors and connectors), just straight connection from each motor to the buttons, which means it should be easy to mod. I’ve seen people adding encoders to the motors and pots so it can be made location aware and be programmed to perform specific tasks.
    Overall I’m very happy with this arm, you can’t find better deal for the price.
