Featuring 6 axes of movement including a 270° rotating base and a precision gripper with a 47mm opening, this eco-friendly kit requires no batteries and encourages problem-solving and analytical skills. With clear instructions and multiple hours of build time, it’s perfect for future engineers eager to master robotics and hydraulics. ## Description "Young engineers will be delighted with the new HydroBot Arm Kit. 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+. " ## Features - BUILD WORKING ROBOTS: Teach your kids mechanical engineering in a way they can't resist! Designed for kids 12+, this kit will guide your learner through the process of building real, working robots - taught in a way that they'll understand! - POWERED BY WATER: Use the power of hydraulics to harness and control the Hydrobot! The arm includes 6 different axes and can rotate up to 270 degrees - no batteries required - MOVES, ROTATES & GRABS: Use the levers to control the gripper which can open and close or be replaced with suction components to pick up objects - NOT JUST ROBOTICS: With our Teach Tech Kits, the learning doesn't just stop at robotics. Teach Tech instructions are specifically designed to develop problem solving skills, analytical thinking and curiosity in young minds - Hands-on Building: This is an in-depth STEM building project, not a pre-assembled toy.

Expect multiple hours of build time. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07NVFGH2X | | Age Range Description | Kid | | Best Sellers Rank | #50,557 in Toys & Games ( See Top 100 in Toys & Games ) #493 in Educational Science Kits | | Brand Name | Teach Tech | | Customer Reviews | 4.5 4.5 out of 5 stars (1,604) | | Educational Objective | Coding Skills, Problem Solving Skills, Programming Skills, STEM | | Global Trade Identification Number | 00756619012728 | | Included Components | Assembly Parts, Instruction Manual in English | | Item Dimensions | 15.6 x 11.4 x 4.1 inches | | Item Type Name | Elenco Teach Tech “HydroBot Arm Kit”, Hydraulic Robot Arm Kit, STEM Building Toy for Kids 12+ | | Item Weight | 2.8 pounds | | Language | English | | Manufacturer | OWI Inc | | Manufacturer Maximum Age (MONTHS) | 1296 | | Manufacturer Minimum Age (MONTHS) | 144 | | Manufacturer Part Number | TTR-632 | | Manufacturer Warranty Description | 1 Year Warranty Against Manufacturer Defects | | Material Type | Plastic | | Model Number | TTR-632 | | Number of Items | 1 | | Number of Packs | 1 | | Set Name | Single Set | | Size | Pack of 1 | | Subject | Physics | | Theme | Cartoon | | UPC | 756619012728 | | Unit Count | 1 Count | ## Images ![Teach Tech “Hydrobot Arm Kit”, Hydraulic Kit, STEM Building Toy for Kids 12+ - Image 1](https://m.media-amazon.com/images/I/71ncvs3cT9L.jpg) ## Available Options This product comes in different **Subject** options. ## Questions & Answers **Q: Is there a way to get replacement parts? 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! ## 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.at/products/132997932-teach-tech-hydrobot-arm-kit-hydraulic-kit-stem-building-toy](https://www.desertcart.at/products/132997932-teach-tech-hydrobot-arm-kit-hydraulic-kit-stem-building-toy) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-08-26*
