KOSMOS Robotic Arm Experiment Kit 620028

Discover the fascinating world of hydraulics and robotics with the KOSMOS Robotic Arm Experiment Kit (model 620028). This STEM educational toy lets you build a fully functional robotic arm powered entirely by water pressure — no batteries or motors required. By assembling over 200 high-quality plastic parts, you will create a 6-axis manipulator that can lift, grip, and move objects up to 50 grams. The manual lever control system provides intuitive operation, teaching fundamental principles of physics, mechanics, and fluid dynamics. Ideal for young engineers aged 10 to 14, this kit promotes fine motor skills, problem-solving, and an understanding of real-world engineering concepts. The detailed, illustrated instruction manual guides you step by step through the assembly process, which takes approximately 2 to 4 hours. Once built, the arm can reach up to 30 cm and features a functional claw gripper. Perfect for science fairs, classroom projects, or at-home exploration, the KOSMOS Robotic Arm offers endless hours of educational fun.
