S & N Hydraulic Robot Arm

A build-it-yourself robotic arm powered by hydraulics rather than motors. Once assembled from the pre-cut plywood parts, children work the independent circuits to grip, lift, twist, lower and release, learning the basics of hydraulics and robotics. A hands-on introduction to engineering that rewards patience and problem-solving. Made from sturdy plywood on an MDF base. Best from around 8 years.
