Kidzlabs: Mega Hydraulic Arm

Build an impressive 18-inch robotic arm and discover how hydraulic power can create controlled mechanical movement using only water. Four precision controls operate the multi-axis arm, allowing it to rotate, lift, move, and use its gripper to pick up small objects. Building and operating the working model seamlessly introduces hydraulics, fluid mechanics, robotics, physics, and engineering while strengthening problem-solving, logical thinking, fine motor skills, and hand-eye coordination. A small crosshead screwdriver, lubricant, and a clean used tin can are needed for assembly. No batteries are required.
