  • The PENDULUM model kit is one of the most basic and reliable timing mechanisms. After assembly, the mechanical pendulum toy (learning toy) works based on the constant amplitude fluctuation under gravity (weight) and the potential energy (tension) of the rubber band. Like other UGears kits for adults and children, this learning toy has a special design and moves.
  • Educational Entertainment: UGears STEM LAB helps children to be educational and have fun. Our construction toys (technical toys) demonstrate the basic concepts of science, technology, engineering and maths and help children explore things in the real world. The fun and practical experience of building is complemented by a comprehensive and thorough understanding of the operating principles of each mechanism.
  • LIFETIME SKILLS AND KNOWNESS: This new collection of 3D puzzles and construction toys for adults and children is unique as it covers frequently used mechanisms, gears and connections as well as their applications. Our scientific sets (mechanical models) are fun for children. It'strengthens endurance. Everything you need is in the box. No gluing or cutting required.
  • Beautiful gift box: with a practical cardboard packaging, the UGears science kits (construction toy package) are an exclusive gift for children and adults. Our STEM toys stimulate the desire for more knowledge and provide hours of fun. All of our mechanical puzzles for adults and children transform into beautiful decorative pieces.

Learn how the PENDULUM works

The Pendulum is a stylised educational model, an interactive study guide to the mechanism, only for learning its essentials and principles of working. The pendulum is one of the basic and most reliable time measuring mechanisms. Its working principle is based on the model's constant amplitude oscillation under the force of gravity (weight) and potential energy (tension force) of the rubber band. The rubber band powers the mechanism of the model and compensates for the pendulum's oscillations' kinetic energy loss. The device is animated by means of gear unit with a windup wheel.

The model has an anchor escapement controlling the frequency of oscillations, a weight, a scape-wheel, gearing, rubber band, ratchet, and pawl reducing operation error. The model has several means to control the frequency of oscillations: the weight of the pendulum bob, the vertical position of the weight on the pendulum, and the tension of the rubber band.

When and who invented it

The first study of the pendulum was implemented by Galileo Galilei, an Italian engineer in the end of the 16th century. He described the property of the pendulum to preserve the consistency of the oscillations. The first person to use a pendulum in a mechanical clock and ensure a steady rate was a Dutch physicist Christiaan Huygens back in the 17th century.


Pendulums are mainly used in mechanical clocks as an element of a launch mechanism and the way to provide a steady rate. In the musical sphere, metronomes that have pendulums as their chief constructional element, help musicians practice playing to a regular tempo. Pendulums are also used in geological surveying, seismography, sports, and laboratory research in mechanics and physics.

Mechanism STEM wooden toy «Pendulum»
The mechanism of the Pendulum is composed of:
  • Escapement wheel
  • Needle indicator
  • The pendulum with the anchor
  • Pendulum bob
The Pendulum is developed to serve as a learning tool rather than a puzzle.

Just like the rest of Ugear’s collections, putting STEM-lab models together is fun and comprehensive: everything you need to build, learn, and discover comes in a box. There you will find:

  • High-quality wooden boards with pre-cut details and other standard supplies. Assembly requires no glue or additional tools. The details come out of the boards with a slight push.
  • Detailed step-by-step color instruction manual. Easy to follow – easy to learn.
  • Examples and suggestions for your fun hands-on projects.
  • QR-code to Pocket Model’s Study Guide (the Pendulum Essentials with a description of the mechanism, principle of working, main characteristics, definitions, and formulas).
  • QR-code to Ugears AR Application. New exciting features from Ugears to make your learning experience even more fascinating!

Ready to Build

Ugears models are made from sustainably sourced, laser cut plywood sheets. Everything you need is inside the box, so you can get building right away.


No batteries, no electricity, just Ugears. All mechanical models are powered by the ingenious mechanisms built by you. Just wind up your model and watch it come to life.

No Glue

Pieces have been designed so they will either click or slide into place. No glue or any other kind of adhesive is needed to build your model.


Models take inspiration from real life inventors and engineers, such as Da Vinci and Galileo. Learn the history behind the model as you build.
