Building conventional robots typically requires carefully combining components like motors, batteries, actuators, body segments, legs and wheels. Now, researchers have taken a new approach, building a robot entirely from smaller robots known as 'smarticles' to unlock the principles of a potentially new locomotion technique.

A Research group reports a way of constructing DNA-based microcapsules that hold great promise for the development of new functional materials and devices. They showed that tiny pores on the surface of these capsules can act as ion channels. Their study will accelerate advances in artificial cell engineering and molecular robotics, as well as nanotechnology itself.

Researchers published the first experiments to gauge whether biomimetic robotic fish can induce fear-related changes in mosquitofish, aiming to discover whether the highly invasive species might be controlled without toxicants or trapping methods harmful to wildlife. Their findings indicate that even brief exposure to a robotic replica of the mosquitofish's primary predator can provoke meaningful avoidance behaviors and physiological changes associated with the loss of energy reserves, […]

Inspired by octopuses, researchers have developed a structure that senses, computes and responds without any centralized processing -- creating a device that is not quite a robot and not quite a computer, but has characteristics of both. The new technology holds promise for use in a variety of applications, from soft robotics to prosthetic devices.

Human hands are skilled at manipulating a range of objects. We can pick up an egg or a strawberry without smashing it. We can hammer a nail. One characteristic that allows us to perform a variety of tasks is the ability to alter the firmness of our grip, and researchers have developed a two-fingered robotic hand that shares this trait. The goal? Improving safety in industrial settings where robots work with people.
