Build your own doodling robot with the Doodling Shake Bot DIY STEM Kit — a fun, hands-on project that lets students draw wild, swirling artworks while learning about vibration, motor mechanics and circuits. With a compact size of 5 in (12.7 cm) tall and 4 in (10 cm) diameter, this kit is ideal for classroom experiments, science clubs and creative craft time.
No soldering required — simply assemble the motor, switch and marker-pen legs, insert one AA battery and watch the bot jiggle across paper, leaving fascinating patterns as it surprises and delights. Perfect for kids age 8+ (typically 14+ listed), it teaches fine-motor skills, circuit basics and engineering design in one tidy package.
This shake bot kit uses a small DC motor that, when powered by an AA battery, vibrates an off-balance weight. The vibration causes the legs (holding marker pens) to move erratically, translating the motor’s energy into jittery horizontal motion across a sheet of paper. The shifting marker legs leave drawn lines as the robot moves, creating swirling art while demonstrating fundamental mechanics: motor loops, vibrations, center of mass, and basic circuit connections.
Q: Can it work on any surface?
A: For best results, use a large sheet of paper on a flat, low-friction surface. Carpet or heavy texture may slow movement.
Q: Do we need tools or soldering?
A: No soldering required. A small Phillips-head screwdriver is included for assembly.
Q: Is the battery included?
A: No. The kit is powered by one AA (1.5 V) battery which is not included.
Q: What age range is suitable?
A: While labeled 14+, the kit is ideal for ages 8+ with adult supervision for younger builders, especially during screw assembly.
Q: Can this be adapted for a science fair experiment?
A: Yes — students can explore vibration frequency, weight distribution, pattern complexity and surface effects using this kit.
