Meet HydroBot Arm Kit

The HydroBot Arm Kit invites young engineers to explore mechanics with a water powered hydraulic system. No motors or batteries are required—just water, air pressure, and curious hands to bring movement to life. The kit emphasizes tactile building and real gadget feel, from the click of levers to the smooth, measured motion of the arm.

Designed for aspiring engineers ages 12 and up, HydroBot blends tinkering with problem solving. Its six axes of motion and a base that rotates up to 270 degrees unlock broad reach and diverse tasks, making the learning journey as wide as the arm itself. From delicate placements to broader sweeps, this kit invites experimentation and thoughtful planning.

What you build

  • Six axes of motion plus 270 degree base rotation for versatile reach
  • Gripper with a 47 mm opening and wrist rotation up to 180 degrees
  • Elbow range of 44 degrees, shoulder motion of 45 degrees, vertical reach 16.35 in
  • Horizontal reach 12.42 in and lifting capacity up to 50 g
  • Removable grippers that can be swapped for suction components for smooth surfaces up to 50 g
  • Clear, animated instructions that guide assembly and operation step by step

How it works

  • Powered by water to move the arm via hydraulics, with no batteries needed
  • Lever controllers include a braking system to support fine, precise tasks
  • Gripper action can open and close or switch to suction for handling objects

Learning through play

Beyond robotics, the kit is crafted to nurture problem solving, analytical thinking, and curiosity. The real hardware and guided steps help learners plan, test, and iterate as they build confidence in technical ideas.

Getting started

Best suited for future engineers 12 and up, HydroBot is a hands on, in depth STEM project designed to be enjoyed over multiple build sessions. The experience emphasizes exploration, careful assembly, and thoughtful use of hydraulic power to accomplish tasks that feel rewarding and tangible.
