2 Humans vs automated side.

2 Humans vs automated side. It uses the data such as the position of the ball, the position of the Axes, and goals scored to create an understanding of the game through reinforcement learning.

The documentation is far from perfect because we just scraped some pictures and videos together trying to create instruction. Because this is poorly documented we don't recommend starting this project without a clue what you're dealing with. Dangerous electric power, some money, annoyance.

The component lists are only the parts for one axle if you want multiple you'll just have to duplicate them. Not all parts are present, we had much parts laying around to use.

Bucket: The bucket is the wooden plank assembly which consists of a playing field surround by walls and a bottom plate for extra stability. The mechanism, electrical system, and other stuff are mounted on it.

LRAM: Linear Rotational Axle Mechanism, this mechanism actuates the required movement for the automated players in the table.

LCS: Light Coordinating System this system figures out where the ball is in the field. How he does that is explained in the instructions.

KOS: Knock Off System this is just a simple way how we find out where the axle of the human sides is. We called it KOS because we saw it in another automated foosball table.

    Order Everything

    Omc-Stepperonline: pretty straight forward just sign up, and order.

    Maedler: is a site where we order many mechanical parts. These parts are universal and available on many sites.

    Bearings: maybe it's locally available otherwise many sites are available for orderings these bearings, same goes for Timinig Belt, Pulleys, Retaining rings square axle, Circulair axle, end stops, MDF Plate.

    The Bucket is pretty straightforward, you get a wooden plank 18mm thick. you cut the required pieces out of it to make the field. We used a total piece of 344X122cm. And had something to spare. You need to be a little creative on the holes not everything is done for.

    This undercarriage looks pretty cool. It was drenched with linseed oil. It had no time to dry.

    LRAM (Linear Rotational Axle Mechanism)

    We thought about a rack and pinion system. Electromagnet system, only they're really expensive.

    So we settled for something more simple.

    One part is a linear belt system where a slider is dragged linearly over an axis. there's a bearing clamped into the slider. Which allows for free rotation whilst the linear movement.

    The inside was the first circular with a feather key inside it. The other part would slide through. The problem we ran into was that the friction was too high. So we used a rectangular aluminum extrusion with the same mechanical principle in mind, only a different shape to translate the force to.

Unfortunately nowhere. This is all we got so far, we'll be updating this project as the project develops.

Nice work. I've made something similar.

That's a very nice mechanism. A lot more compact than ours.

That's an interesting challenge to keep the linear agility of the rods as fast as possible while also being able to rotate them fast enough to send the ball flying. Actually gives me a lot of appreciation for what the human players are able to accomplish.

There's indeed a lot to appreciate about the human players. As you said we need to keep the linear as well as the rotational agility high, to maximize the agility we need quick acceleration by minimizing mass inertia and maximizing actuation force. A lot of universities have interesting solutions, but one thing is sure that our mechanism is one of the cheapest to build.
