Promising PID Controller Calculation

The common and predominant way for applications requiring continuously modulated control – like keeping the shiplet in stable submerged balance – is to use a so called proportional–integral–derivative (PID) controller to calculate the actuators’ actions based on the input of the sensor data in a continuous loop. As described in the former post Cybernetic Marine[…]

Shiplet Launching Ceremony

Even though it is a bit hard to tell when exactly we’ll feel ready for it, there will be a hilarious get-together around the official launching of the first [(fully)] functional 1:100 scale model prototype of OHANDA ONE – aka the shiplet. We plan to welcome everyone who wants to join at a waterfront in[…]

AHOD I – All Hands On Deck!

Preparing for a simulation / summer camp for an enacted journey on Ohanda One 2025 Ohanda.One is a long-term utopian science fiction (project) played out by an international, transdisciplinary group of Open Knowledge Enthusiast, designing, building and operating a futuristic zero emission ocean vessel. The vessel will host about 150 to 200 people for traveling[…]

History Repeating?

In April 1875 Sir Henry Bessemer launched the Bessemer Saloon Ship, an experimental Victorian cross-channel passenger paddle steamer, intended to combat seasickness with a swinging cabin, a concept devised by the engineer and inventor that he patented in December 1869. The cabin was designed to pivot independently of the ship’s hull, suspended on a system[…]

Good to go?!

After 7 years of prototyping it feels almost a bit unreal when we suddenly start wondering what actually still needs to be done before the shiplet’s first test run on open waters. Besides continuous iterations of optimizing the code it looks like there is not so much left to do at the moment. Are we[…]

Balloon Blast

In free-style scale model prototyping one can daydream into that microcosm, where you can do miraculous pointy-headed things you could never do in full size reality. A good example for this is to use air balloons from the jamboree store to level and balance the shiplet’s position and mass distribution inside the tubular ballast tanks.[…]

Sviveling Static Sails

Inspired by the DynaRig, designed in the 1960s by the German engineer Wilhelm Prölß, we decided to equip the shiplet with likewise sviveling, but static sails. We will use radio controlled servos to manually rotate the konvex profiles within our pivoted mast supports, also to test detrimental positions and situations. To start with, we use some[…]
