Hydraulic Robotic Arm Construction Set

This build-it-yourself robotic arm is hydraulic powered.


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.

    Super inspiring and fun to build. Water evaporates over time so remember to refill the water from time to time. Very cool.
