Product Details
1. Lifelike Jellyfish Movement The biomimetic model features a transparent, umbrella-like head that undulates slowly. Together with tentacles swinging on a mechanical linkage, the movements create the illusion of a jellyfish gliding weightlessly through water. 2. Motion and Display Modes The model sits on a circular base with a touch button that switches the model's mode. The Jellyfish drifts for 3 minutes in Motion Mode, while lights flicker softly for 30 minutes in Display Mode. 3. Four Light Modes Choose between four light modes, including Strobe Awakening, Slow Breathing, Flashing Alert, and a Red Burst. Crystalline fluorescent tentacles complete the glowing effect. 4. Motor and Power Source A compact micromotor with a planetary gear system spins at 3000 rpm and delivers 500 g·cm of output torque through a 1:120 reduction. The motor sits in its own housing, which keeps the Jellyfish's movement smooth and steady. Power source: 3 AAA 1.5V batteries 5. Medium-Difficulty Puzzle The mechanical 3D puzzle kit consists of 157 pieces with a 3-out-of-6 star difficulty level and around 2 hours of assembly time.
Designer's Journey
Jellyfish have thrived for hundreds of millions of years, supporting ocean ecosystems and inspiring robotics, not relying on speed, strength, or size to earn their place in the ocean. All this without even having a brain, heart, or bones. They drift with the current, conserve energy, and adapt, proving that a gentle presence can last longer than a loud one. Like the jellyfish, you can endure, contribute, and inspire without being flashy or loud. You can move through life with a calm, steady pace and still be one of the strongest forces the people around you know. Find that calm through the ROKR hobby, glide gently through life, and just be authentically you.
