Pro’sKit GE-632 Hydraulic Robot Arm Kit – DIY STEM Water-Powered Robotic Arm with 6-Axis Control (229 Pieces, No Batteries)

Give kids (and curious adults!) a real engineering experience with the Pro’sKit Hydraulic Robot Arm Kit GE-632 — a hands-on STEM build-it-yourself robotics kit that teaches fluid mechanics through play. With 229 precision pieces, children assemble a fully working robotic arm and control it using hydraulic water power, meaning no batteries, no motors, just science in action.

Once built, this impressive arm offers 6 axes of motion, operated by easy lever controls. It can rotate, lift, extend, and grab objects using either a gripper or a suction cup, helping kids understand how real industrial robot arms function. Just add about half a cup of water to activate the hydraulic system, and watch pressure turn into smooth mechanical movement.

Designed with safe, high-quality materials and clear English instructions, the GE-632 promotes construction skills, critical thinking, and problem-solving, while delivering endless interactive fun. With a lifting capacity of up to 50g, it’s perfect for picking up lightweight objects and experimenting with real robotic tasks.
