In this log we will present our solution for the funny action in the Eurobot competition. At first we thought about an umbrella shaped solution. Here it is the umbrella we did with SW, the blue ring is a 3D-printed part.

The concept was to pull up the parasol out of a metal circle and gravity would deploy it.

We were focused on an umbrella shape. This solution worked perfectly but the mechanism was too complex for such a simple task, increasing the risk of failure.

So we worked to find another solution and here is our final version of our Beach umbrella.

We were focused on an umbrella shape. This solution worked perfectly but the mechanism was too complex for such a simple task, increasing the risk of failure.

So we worked to find another solution and here is our final version of our Beach umbrella.

The mechanism is very simple, the blue part is fixed on the robot and the bar in U is fixed apart. Then we hang together the two metal bar with a piece of fabric. On the right there is the support for the servo, which we designed to be reusable for other tasks.

Here is our beach umbrella closed.

And now open.

We chose this solution because it is simpler to fit it on the robot and this option allows a bigger parasol with a more visible logo.
