It is powered by water, so no motor needed! They can use the levers and the power of hydraulics to move the multi-axis arm. The lever controllers have a special braking system that helps to achieve fine, accurate tasks. The gripper can open and close with a maximum 47mm (1. 89 in. ) gap, wrist joint rotation of 180deg. , wrist joint mobility of 98deg. , elbow joint range of 44deg. , base rotation of 270deg. , and shoulder joint motion of 45deg. , with a vertical reach of 16. 35in. , horizontal reach of 12. 42in. , and 50g lifting capacity. Grippers can be removed and replaced with suction components to pick up objects with smooth surface areas of no greater than 50g (1. 75 oz. ). The clear, animated instructions make the assembly and operation of this STEM robot easy to understand. Best suited for Future Engineers 12 and up. Elenco Teach products are based on STEM activities (Science, Technology, Engineering, Math) to teach and encourage kids in their development, all while having fun! All Teach Tech Green-Energy robots are powered by either water, wind, or sun, so there are no batteries required. Perfect for future engineers ages 12+. " Review: Challenge to assemble but valuable to teach/learn - With some engineering background, we put it together successfully right away. It took several hours to assemble and I will admit, getting the hydraulics loaded correctly is a bit of a challenge for any 12-year-old without adult supervision. Even then, I could see a lot of folks being overwhelmed by the challenge of not only assembly, piece by piece, with no room for error, to the water-loading hydraulic portion of the assembly. Set aside plenty of uninterrupted time, "roughly" first 40 pages are robot assembly, second 40 pages are hydraulics/pumps/tubing. If you're looking to get your kids interested in robotics, STEM/STEAM, or engineering/manufacturing this is a relatively inexpensive introduction to test the staying power of this low-level technology and their interest. It will also test your patience. Although we've played with it enough now that it's already showing signs of wear and the parts/levers are getting loose. Overall, great introductory toy to robotics! Review: Hydrobot arm kit - This kit went to my 13 year old grandson in another state. He's a smart kid and leans toward science. He was excited to get it and a few days later he sent the video. Great summer project he had fun putting together, as well as a learning experience about hydraulics. ## Features - BUILD WORKING ROBOTS: Teach your kids mechanical engineering in a way they can't resist!

My child is really enjoying building this robotic arm, unfortunately some of the tiny parts are lost** A: Horrible customer service with the company, don't offer replacement or replacement parts. Told us to use zip ties to hold it together. Biggest waste of money and a piece of junk. Wouldn't recommend **Q: Why are there two different prices for this product? One is $37 and the other is $59... I don't see a difference in either product. Please help!** A: The product is being sold from two different vendors. Teach Tech is our brand. **Q: How many pieces** A: Thank you for your inquiry. There are more than 230 parts in this kit. I hope this helps! **Q: Arm not working , my son build the arm but the front part or the claw does not pick up stuff** A: hi its actually for me a con. my son is 12. very difficult to assembly and its not a robot! if the arm doesn't work its a pain. it means there is air in the tube so he has to desassumble it, get rid of the air using 2 water sources for each end of the tube and then reassembly it. as i said we were very dissapointed with the product. however its very educative in terms of engineering! ## Customer Reviews ### ⭐⭐⭐⭐⭐ Challenge to assemble but valuable to teach/learn *by 0***Y on December 27, 2024* With some engineering background, we put it together successfully right away.

Overall, great introductory toy to robotics! ### ⭐⭐⭐⭐⭐ Hydrobot arm kit *by P***D on July 17, 2026* This kit went to my 13 year old grandson in another state. He's a smart kid and leans toward science. He was excited to get it and a few days later he sent the video. Great summer project he had fun putting together, as well as a learning experience about hydraulics. ### ⭐⭐⭐⭐ A nice, if small, workable robot arm to show principles. *by F***K on October 30, 2020* Start to finish assembly took right at 8 hours, spread over 3 days. I am a moderately skilled senior citizen. This is no trivial assembly. The good news is that the instructions are very clear, and the parts generally fit together well. However, assembly requires *close attention* to the images/directions, which can wear you down if you try to do it in one sitting. I am tracking my hours to see how long the whole assembly takes, and will share those later. Some hints: 1. DON'T throw away the little envelope that says "don't eat this". I thought it was some kind of dessicant but it is oil essential to project. 2. You will need a *small* phillips screwdriver, with bit fits screw heads well, because some are tight. Lots of pressure and slow turning of screwdriver was necessary for many of the screws. 3. Put a new blade in your utility knife to trim off the innumerable tabs. Update - carefully cut items from matrix with knife to avoid separate removal of tabs 4. Be methodical, and careful with the **small** parts (and tiny screws). Put items in ziplok bags & containers as you go. No spare screws or springs are provided so DON'T LOSE any. (I'd have paid the extra $0.20 or whatever) 5. Filling the pneumatic system components with water was the most nerve-wracking - mainly because of the difficulty of eliminating water bubbles. I suggest getting a large container for water, big enough to submerge your hand and enable you to hold items upside down when filling. Move plungers multiple times to eliminate air from cylinders. 6. The filling instructions were a little confusing to me, but basically they want you to fill the cylinders BEFORE attaching hoses. They don't tell you explicitly but I think their procedure is designer to minimize bubbles in tubes that you fill with water. 7. Hoses are very slippery when wet and hard to push on all the way, but a BIG help was using a high-tech "wicking" sweat rag - the artificial fiber gave a good grip on tiny pipe. Also good for mopping up spills. 8. I tried to fill the little hoses by gravity flow before connecting to cylinders, rather than when they were dry. Little bubbles tend to form in dry pipe when first wetted. Maybe it helped a little. Oh, and yes, trying to correct big bubbles later, after complete assembly would be a nightmare - so do your best while filling initially. 9. Installing the levers and cylinders in the base unit is easiest to do from the bottom, rather than from top as they show. I was sure I was going to crack the plastic several times when pushing cylinder assembly ( the enc with spring) to lock under/into control lever. It is very tight but never broke. 10. The unit worked OK when finished - it won't replace a robot arm in a GM factory, but it is simple to use and will hopefully be entertaining to 4 year olds. Time will tell if it is durable enough for that age user. ## Frequently Bought Together - Teach Tech “Hydrobot Arm Kit”, Hydraulic Kit, STEM Building Toy for Kids 12+ - Thames & Kosmos Mega Cyborg Hand STEM Experiment Kit | Build Your Own GIANT Hydraulic Amazing Gripping Capabilities Adjustable for Different Sizes Learn Pneumatic Systems - Thames & Kosmos Hydraulic Boxing Bots STEM Experiment Kit | Build Two Hydraulic-Powered Boxing Robots! | Explore Hydraulic, Water-Powered Systems | Challenge a Friend to a Robot Duel! --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/132997932-teach-tech-hydrobot-arm-kit-hydraulic-kit-stem-building-toy](https://www.desertcart.pl/products/132997932-teach-tech-hydrobot-arm-kit-hydraulic-kit-stem-building-toy) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-08-12*
