'Lego ball-carrying device: 5 rings' full of industrial robot feeling that delivers balls endlessly with a robot arm

There are various enthusiasts in the world-famous block toy 'Lego', and there is

a genre called 'Great Ball Contraption (GBC)', a huge device made of Lego blocks that keeps carrying balls endlessly. 'Lego ball carrier: 5 rings ' created by Akiyuki, who creates modules, sorters, robot arms, etc. related to GBC, is an industrial robot in which the robot arm connected to the circular ring keeps carrying the ball endlessly. It is a device made of Lego block like.

As the name implies, Akiyuki's 'Five Rings' are made up of five ring-shaped Lego. The individual ring looks like this.

Connect the first stage and the ball supply mechanism that serves as the base.

Each ring is angled with respect to the base side, and each arm collects the ball passed from the supply mechanism ...

The mechanism that the ball falls when the arm reaches the highest point.

Fully automatic drive is also possible by connecting a motor.

In the movie, connect the second ring. The feature of the second stage ring is that it is angled so that it alternates with the first stage.

The ball is delivered by the mechanism that the arm of the second stage ring reaches the lowest point corresponding to the moment when the arm of the first stage ring reaches the highest point.

It is said that the shape of the saucer has been improved many times to become the current shape.

So, after that, connect the ring up to the 5th stage in the same way. Since the ring has a modular structure, it is possible to increase it to 5 or more stages.

Attach a rail to collect the balls carried to the top ...

Install a spiral module that returns the ball collected on the rail to the initial point ...

Complete.

The arms of the five rings carry the balls one after another, and the collected balls also return to their original points, so an infinite loop in which the balls continue to be carried as long as power is supplied.

About 4 balls are spilled per hour.

It is a sight that you can keep watching innocently as each part that is precisely combined keeps moving.

Also, in the latter half of the movie, the state of the mode in which the turntable is connected to the base part and the entire mechanism keeps moving with uneune is also recorded.

The above 'Lego ball carrier: 5 rings' can be purchased from Akiyuki's official page as a set of instructions, parts list, and CAD data for 1100 yen.
