On 28th, I arrived in Barcelona to attend a training on remotely operated (underwater) vehicles (ROVs).
The first day of class covered a familiarization about ROVs, involved physics, and components. Many of the components are electronic components. Nevertheless, their complexity seams not be too high and the technology used dates from the late 90’s — which allows for maintaining and fixing the electronics without special equipment.
After the class finished, I walked along the beach to the center of Barcelona, and took the train back. It was as I remembered it from my previous visits: Certainly a touristic, but pretty and artistic city.
