About this item

The Hydrobot Arm is a STEM building project where kids construct a fully working robotic arm powered only by water hydraulics. Multiple hours of assembly walk young engineers through real mechanical principles — levers, joints, and pressure control — with no batteries involved. Once built, the arm rotates, bends, and grips using precise lever-controlled hydraulics, and the gripper can be swapped for a suction attachment. A great pick for curious minds 12 and up who like building things that actually move.

Build a real hydraulic robot arm from scratch — a hands-on STEM kit, not a pre-assembled toy
Runs entirely on water pressure through lever controls, no batteries or motors needed
6 axes of movement with base rotation up to 270°, plus wrist, elbow and shoulder joints
Gripper opens up to 47mm and lifts up to 50g; swap it for suction cups to grab smooth objects
Vertical reach of 16.35 in and horizontal reach of 12.42 in once assembled
Recommended for ages 12+, with clear step-by-step illustrated instructions
