1. The mechanical arm consists of 220 parts, which can exercise children's logic, hands-on skills, explore scientific principles, use their imagination and feel the fun brought by the hydraulic arm. Children are delighted to have the robotic arm kit, which is powered by water, so no motor is needed! 2. They can use levers and the power of hydraulics to move the multi-axis arm. They can use the force of levers and hydraulics to move the multi-axis arm. The lever controller has a special braking system that helps to achieve fine and accurate tasks. 3. The width of this robotic gripper is 48 mm and weighs no more than 100 grams. The width of the gripper is 48 mm and the weight should not exceed 100 g. The suction cups can pick up items with a weight of no more than 100 g. 4. The hydraulic robot arm can rotate, rise, fall, bend, and move flexibly with 180° of wrist rotation, 90° of wrist movement, 40° of elbow movement, 45° of shoulder movement, and 270° of base rotation. 5. Scientific assembly experiments with clear animated instructions make the assembly and operation of this STEM robot easy to understand. Most suitable for future engineers aged 8 and above, enjoy happy parent-child time. 6. It is recommended to bring your own tools in advance to facilitate your child's assembly, including: diagonal pliers, Phillips screwdriver, scissors, paper towels, markers, tape measure or ruler, water cups, come and enjoy your DIY activities together!
