It teases curiosity to know more about this fascinating alternative to conventional currency and at the same triggers unease about its bad reputation. New research is… read more »

Enhancing the locomotion of small robots with microwheels

Microbots could have several useful applications, particularly within biomedical and healthcare settings. For instance, due to their small size, these small machines could be inserted within the human body, allowing doctors to remotely carry out exams or operate regions affected by diseases. Developing approaches that enable the effective locomotion of microrobots in medical contexts, however,… read more »
