  • 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 LEARNING FUN: Teach Tech products focus on STEM activities (Science, Technology, Engineering, Math) to teach and encourage kids in their educational development, all while having fun!

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+. "

    • 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! ... show more

    • When they’re too old for just a lego...
Bought this for my 12 year old nephew for Christmas and he really enjoyed putting it together - took his time - read the directions - started it Christmas night and the following day he had it operational! Great gift for the recommended age group.

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. ... show more

    • Looks good except for delivery appearance
I like to purchase Christmas gifts for my grandchildren ahead of time. I was really excited about this hydrobot arm kit. Well, it arrived today in its original packaging. In other words, it arrived in the toy box with two labels stuck smack in the middle of it. I was disappointed in the packaging. I was able to remove the labels but they still damaged some of the cardboard. Other than that, it looks like a nice project set, but for the expensive price, it should have been more carefully packaged. ... show more

    • Absolute blast to assemble and experiment with
My son and I tag-teamed and assembled it in an afternoon, though it requires patience and a steady hand to clip the burs off all the plastic parts. What’s great is that you can tell whoever designed this knew what they were doing and didn’t cut any corners (like a lot of cheap science sets). It’s sturdy and the hydraulics work really well. There’s an hydraulic GLOVE kit that I recommend getting first, then follow up with this for a perfect combo. ... show more
