OWI Robotic Arm Edge

Love this set! It is great for someone who is starting out and has a lot of room for enhancements if you want to dwell deeper into it!

little hard but very nice working. Right now I am typing with my robotic Arm

A very good quality product

price for the same from other source is less by1000 Rs

Very Useful Produt. Value for Money. Even used for Teaching Engineering Students Final Year Mechanical..

Product is Awesome.Suitable to do programing as well.Installation will take some time.

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 degreesElbow 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.

Llego rápido el roducto y en condiciones excelentes, contenido completo ninguna pieza faltó y el manual es excelente explica bien aunque está en inglés pero es lo de menos y muy padre poder armarlo

I bought this for my 9 year old son. I have to admit that this kit is not easy enough for a 9 year old to build on his own, but it's easy enough for kids of that age to play with once built. Instructions were great but the screw list was a little hard to follow. It's easy to use the wrong screws in the wrong areas. The arm can lift up to a D cell battery. Anything over that weight and the grip is not strong enough to hold it. Even though it's small and weak it's still great fun. It has a wide range of motion and looks freakin cool. As an adult I can honestly say this toy is worth the money and would even recommend this toy to schools interested in educating kids in robotics. The kit is designed to protect the gears from stripping by allowing two parts to slip and make a clicking sound whenever it is pushed beyond it's capabilities. My son has learned a lot from this toy. He saw how it's built, what the parts do and how it all came together. Best of all he takes the darn thing everywhere he goes and shows it off to anyone he can show it to. He proudly says, "look what daddy and I built". I'm very happy with this purchase and plan on buying another if this one breaks.

This little robot arm is great and fun to play with. Assembling is another story. The tiny hex nuts will make you angrier than you have ever been in your entire life when they pop out of place as you’re tightening the entire gear box. I had to assemble each gear box about 2-3x simply because of the hex nuts. Turns out, you have to hold the gear box together as tightly as humanly possible while tightening the screws to get them to stay. My hands are raw and sensitive now. Other than that, assembly isn’t bad at all. I almost returned this because of the gear box assembly. They should glue the hex nuts in place before giving it to the consumer. Also, make sure you have a very small Phillips screw driver before attempting to assemble. Would have been nice if that was included.
