Find out about the Random Generator and learn how it works

For generations, humanity has been futilely wrestling with perennial questions, such as whose turn is it to take out the rubbish? Who will hoover today? And, of course, who does the dishes?

Those who volunteer to do all these chores have our eternal respect, but what if no one volunteers? The fair way to handle this would be to let chance decide and throw a coin. If you have ever bet on heads or tails, this means you got close and personal with probability theory and its practical application.

Ugears suggests an alternative to the classic coin solution that is not only elegant and fun but has an extra educational benefit. To all the questions there is now an answer with Ugears Random Generator of the STEM lab Collection.

The Random Generator, as you might have guessed from its name, is a device that generates random numbers and provides different random results based on probability theory. How it does this is exactly what the Ugears STEM model will demonstrate.

The main element of the Random Generator’s design is a cube with an octahedron inside it that in its turn contains a metal ball to provide weight. This construction is powered by a rack-and-gear drive initiated manually and providing energy through a driven gear that rotates a three-axle gear. This is how the cube with all its contents begins to move, which is important for summoning the magic of randomness. Of course, we can only call it magic until we know the science of it. And to learn it, let us take a closer look at the main structure.

The vertices of the octahedron coincide with the sides of the cube. In this way as the energy of the system expires and it stops moving, gravity suspends the metal ball in the lowest part of the octahedron and due to the inclination of the walls it rolls within, it ends up in one of the octahedron’s vertices pulling in down. Whichever of the vertices turns up in the bottom, the side of the cube it is attached to will be right under it and parallel to the floor. In this way, the side of the cube with the answer will be the one facing up on the opposite side.

The probability to get any of the vertices facing down is virtually the same due to symmetry of the octahedron that rotates freely around the axis of its mass. This leads us to a simple conclusion that the probability to receive one of six answers is 1/6 or 0.167.

Every side of the cube positioned by the vertex of the octahedron, has a message: one says “YES”, the other “TRY AGAIN”, etc.

*An octahedron is a regular polyhedron with eight faces (equilateral triangles) and six vertices.           

The mechanism of the Random Generator is composed of:

●        Button

●        rack-and-gear drive

●        overrunning clutch

●        driven wheel

●        three-axle gear

●        Cube

●        internal octahedron

●        Weight

 

Ugears STEM models are designed to suit different age groups with a special focus on learning component. The assembly of the model will be interesting and won’t take much time.

STEM lab Model kits come with all you need in a box.

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:

  • Wooden details pre-cut with a precise high-tech laser in high-quality plywood boards, as well as other materials required for assembly. The models need no glue or additional instruments to build. The details come out of the board with a slight push.
  • Step-by step illustrated assembly instruction manual.
  • Practical lab tasks with use of your model.
  • QR-code to download a pocket study guide about your model, its mechanism, principle of its working, main characteristics, physical and mechanical formulas, and fun practical tasks.
  • QR-code to download AR-application. Fascinating innovation from Ugears – new drive to learn more new things!
