    • "The Best Christmas Present Yet!"
The Robotic Arm Edge was one of our 10 year old son's top five Christmas requests. In the end it proved to be a great pick. He spent approximately 4 hours from start to finish to complete the project, with some guidance along the way from Dad. Once it was finished however, it did not work and he was discouraged. By then it was late and we were all tired, so we put it aside for evening. The next evening we went back to the troubleshooting page and read over the reviews here at Amazon to give us some clues about what the trouble might be. We also tested the wires and motors independently, one at a time, using a 9-volt battery and two wires to create a circuit with each motor. We knew that all of the connections were good because the motors and gears worked properly when powered by the nine volt battery. We then checked the battery terminals. We discovered they were not bent and positioned down properly. Once the terminal placements were corrected, we were able to get some partial movement with the control box levers, but only in one direction. We removed the top of the control box and 'warmed up' the metal plates by pressing each of them down manually in each direction with our fingers, to ensure they were making contact with the circuit board, and the robotic arm's mobility greatly improved. (You may have to repeat this step occasionally to maintain full mobility, double check wire connections, and make sure that the wires are not being crimped, tangled or pulled out of position by the movement of the arm. The wire clips are very helpful when placed correctly for this reason). The movement specs* from the manual are as follows: Gripper: 0-1.77" Wrist motion: 120 degrees Elbow motion: 300 deg. Base motion: 180 deg. Base rotation: 270 deg. Search light: on when on switch is on. *We found these measurements to be pretty accurate. Finally, we smoothed off a few plastic 'burrs' that were catching as the robotic arm spun on it's base, untangled and repositioned a few wires to keep them from tugging and pulling out of their connectors as the arm revolved, screwed the control box back together, and Oila! The robotic arm now works beautifully, LED light and all. Our son declared, "I am Satisfied!" with a huge grin and a sigh of relief :) It was great outcome to a slightly challenging project. The gearboxes were a bit taxing to put together from a 10 year old's perspective, but he stuck with it, even though it was a initially frustrating. After putting together several of the gearboxes he was a pro. We encouraged him to take his time and read the instructions thoroughly to become familiar with the concept and sequence of steps before he began, and we think that really helped to make the project go much smoother for him than it might have otherwise. One precaution: If you hear clicking noises as you move the robotic arm with the controls, that means to stop and go back in the other direction! We have explained that it is important NOT to try to manually force the arm to move in one direction or another, or the gears may break! You may also be trying to lift too much, depending on where the center of gravity is in relation to the weight of the object. Because of the plastic gears and other components, it is a TOY more than it is a tool. Our son is looking forward to using the 'RAE' to assist him in other building kits, such as legos, kinex, and maybe another similar robotic project. The best lesson that came out of this for us was that putting our heads together and combining our knowledge, skills with a little perseverence kept us from giving up on it and assuming there was something defective about the kit. We worked backward and retraced our steps, and it was a great success. What could be better than learning and having lots of fun in the process? :) I am writing this review because we were helped greatly by the informative reviews already posted here, and I hope that what we learned along the way can help someone else, incase they get stuck a bit as we did. It's worth it to press on and find solutions to problems, and our son is enjoying the fruits of his labor and is all smiles now :) The stars were his review of this product. ... show more

    • Fun robotics project
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. ... show more

    • It is cheap
Was not able to put it together as the screws would not go in and stripped, the nuts keep falling off. Not easy to assemble, cheap quality, if you can then its good price but breaks easily.
