Powered by water hydraulics, it features 6-axis movement including 270° base rotation and a precision gripper with a 47mm opening. This eco-friendly, battery-free kit encourages hands-on learning in mechanical engineering, problem-solving, and analytical thinking, making it a perfect educational toy for aspiring young engineers. ## 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+.

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.ro/products/256899633-elenco-teach-tech-hydrobot-arm-kit-hydraulic-kit-stem-building](https://www.desertcart.ro/products/256899633-elenco-teach-tech-hydrobot-arm-kit-hydraulic-kit-stem-building) --- *Product available on Desertcart Romania* *Store origin: RO* *Last updated: 2026-04-25*
