Features
Modou 3 in 1 hydraulic robot arm is a STEM educational tool developed by the Modou Technology R&D team for children by integrating scientific principles and creative design. It drives the robot arm to move through the hydraulic power system, helping children learn physical knowledge, cultivate engineering thinking and hands-on ability in assembly and manipulation. The product is centered on the hydraulic system, using water pressure to convert into mechanical power to drive the robot arm to complete actions such as grabbing, lifting, and rotating. The product is positioned as a STEAM educational tool, aiming to stimulate children's interest in mechanical engineering and physical principles, while cultivating logical thinking and creativity.
Materials and electronic components
Main structure: Made of environmentally friendly plastic or lightweight metal, taking into account durability and safety.
Hydraulic system: Built-in food-grade hose and syringe, liquid pressure is transmitted by manual pressurization, without batteries or motors, green and environmentally friendly.
Replaceable parts: The end effectors such as the chuck and suction cup can be freely disassembled, supporting DIY sticker decoration to enhance personalization and fun.
Manufacturing process
Precision design: The hydraulic system adopts a modular layout, including core components such as hydraulic cylinders, pipes, and piston rods, and is manufactured with high precision through laser cutting and injection molding.
Assembly process: A total of 220 parts are assembled, which takes about 2-3 hours to guide children to gradually understand the mechanical structure and transmission principle. The assembly process requires adjustment of the joint angle and hydraulic transmission structure to cultivate problem-solving skills.
Quality control: We undergo rigorous testing before leaving the factory to ensure the sealing of the hydraulic system and the flexibility of the robotic arm.
Product advantages
Scientific enlightenment: Intuitively display physical knowledge such as hydraulic transmission and Pascal's principle to help children understand the scientific logic of "small force driving large machinery".
Multifunctional expansion: The three-in-one design supports free switching of grippers, grabs, and suction cups to adapt to different scene requirements (such as handling and excavation).
Creative freedom: DIY stickers and adjustable joint design stimulate children's personalized expression and interest in engineering transformation.
Parent-child interaction: Parents need to participate in the assembly process, becoming a high-quality carrier for family science and technology education.
Main gameplay
Basic operation: Control the lifting and retraction of the robotic arm through a manual pressurized syringe to practice the correlation between force and movement.
Scene simulation:
- Handling task: Grab small objects such as building blocks and bottle caps to test the accuracy of the robotic arm.
- Creative transformation: Replace the chuck with an "excavator bucket" to simulate the digging action.
