We devoted the first part of this article to introducing the problem of motion planning for autonomous vehicles at a qualitative level and to briefly describing two of the most commonly-used algorithms, RRT and RRT* . Next, we will continue getting into deeper mathematical details about the topological structure of the state spaces associated to […]

Three main incorporations of physical robots are forecasted in our lives: transport, assistance and factory robots. Design and requisites of these different kinds are quite different, but one particularly is attracting researchers’ efforts: navigation. While transport robotics is located outdoors, the rest two are indoors. Outdoors machines can make use of a GPS (among other […]

Undoubtedly, the most popular aspect of driverless cars, autonomous drones and quadrotors are the cool videos we are getting accustomed to seeing around. However, behind each of those spectacular demonstrations there is a large amount of work, both practical and theoretical. In this series of articles we will shed some light on one of the […]

Some years ago, with a sudden and drastic reduction on the number of honeybees, scientists realized that if these insects disappeared it would be the end of agriculture as we understand it, as they are the main drivers of agricultural pollination in the US . But would we be able to replace these pollinators with […]

It is well known that an accurate and energetic laser shot can melt, ionize and excite the material in which the light is focused, creating very bright plasmas after the interaction. Valuable information can be obtained from the light emitted by the plasma, such as the elemental composition of the material itself or the environment […]

We will address a recent article by Jaillet and Porta (Institut de Robòtica i Informàtica Industrial, IRI), which reveals new practical applications of highly-abstract mathematical entities. When it comes to robots, we can’t forget that their fundamental goal is always somehow related to moving stuff. Arm robots as those found in the automotive industries are […]

The history of science is full of examples of researchers who arrived at the same discovery independently. Unfortunately, this still happens in this information age, thus technological deficiencies are not to blame for this lack of communication between different research communities. Odd as it may sound from outside, I hold that much of this isolation […]
