Hydraulic Robot Arm

Anyone who has seen auto-factory robots at work can appreciate how fascinating hydraulic machinery can be. This model kit lets you build your own hydraulic robot arm capable of picking up and manipulating small objects. No electricity or batteries are required; all the arm’s movements are driven by water pressure and mechanical action. Fully functional with a sturdy design, the finished model is a toy that will provide hours of entertainment (and a better understanding of hydraulics).
