Need a Lift?
Build your own hydraulic-operated robotic arm with this DIY engineering kit! Fun and easy to construct for children and adults alike, this three-dimensional model offers a hands-on exploration of hydraulic power systems through some of the same principles that drive real-world machines. Made from die-cut plywood, the kit's components are precisely cut and can be assembled in 1-2 hours. Once constructed, it can lift small items horizontally and rotate 90 degrees on its base. And of course, this hydraulic helper needs no batteries--simply add water to put it to the test! Made in Taiwan.
WARNING: CHOKING HAZARD - Small parts. Not for children under 3 years.
