This robotics kit introduces kids ages 12+ to mechanical engineering principles through hands-on construction of functional hydraulic robots. The water-powered Hydrobot features a 6-axis arm with 270-degree rotation capability, operating without batteries. Users control movement through lever-operated hydraulics, with interchangeable gripper and suction attachments for object manipulation. The instructional materials emphasize STEM learning objectives, specifically developing problem-solving skills, analytical thinking, and technical curiosity. The curriculum integrates science, technology, engineering, and math concepts through practical application. All components are included for building complete robotic systems that demonstrate core mechanical and hydraulic principles.
