Robot Eat Mechanical Wood STEM Model Bring handson learning to life with this wooden Robot Eat mechanical model. Designed as a STEM project for kids, the kit combines simple mechanics and a mechanical password lock to create an engaging assembly experience that teaches basic engineering and problem solving. Key benefits Educational STEM project that teaches mechanical principles through building and operation. No external power required. The mechanism is based on the dualloop control motor principle and operates mechanically when activated. Interactive coin eater action: place a coin in the robot's hands, and the mechanism raises the arms, opens the mouth, stores the coin inside, then returns it to the hands for the next coin. Mechanical password lock for added challenge and play: turn the code wheels to the correct positions and press the button to unlock, no key required. Encourages fine motor skills, logical thinking, and patience through step by step assembly. Features and specifications Material: Wood Color: Natural wood finish Size: Approx. 120 x 130 x 150 mm (4.72 x 5.12 x 5.9 in) Assembly: Lasercut plywood parts require glue and manual assembly. All parts are supplied on sheets that need to be removed before building. Operation: Mechanical movement that does not require batteries or electric power. Package includes: 1 x Robot Eat kit What makes it stand out Real mechanical action and a working password lock deliver both play value and a practical lesson in basic mechanics. Handcrafted style parts and straightforward structure make the build accessible while still rewarding. Reusable and functional when assembled; finished model can hold small items such as coins or tiny toys. Practical use scenarios Classroom STEM activity: Use as a group or individual project to demonstrate mechanical linkages, gearing, and simple lock mechanisms. Family learning project: A weekend building activity that teaches kids how mechanisms work while creating a functional keepsake. Desktop toy and coin holder: Place on a shelf or desk to store pocket money or small toys in a playful way. Notes Glue is required to assemble the kit. Small parts and manual assembly may require adult supervision depending on skill level. Please allow 1 to 2 cm variation due to manual measurement. Color may vary slightly from images due to monitor differences.
