People should know what to look forward to as more technology becomes readily available for society's consumption, as well as how they can incorporate technology and nature into their homes in the present.

A review paper by scientists at the Beijing Institute of Technology summarized recent efforts and future potential in the use of in vitro biological neural networks (BNNs) for the realization of biological intelligence, with a focus on those related to robot intelligence.

If you've ever wondered what a lack of diversity in robotics looks like, just do a Google image search for "humanoid robot" and check out the simulated skin color of the thousands of robots that fill your screen. (Hint: it's white.)

Carnegie Mellon University engineers have developed a soft material with metal-like conductivity and self-healing properties that is the first to maintain enough electrical adhesion to support digital electronics and motors. This advance, published in Nature Electronics, marks a breakthrough in softbotics and the fields of robotics, electronics, and medicine.

A team of researchers, led by Matthew Gombolay, an assistant professor in the School of Interactive Computing and director of the Cognitive Optimization and Relational (CORE) Robotics Lab at Georgia Tech, are using the sport of table tennis to showcase that humans may not always trust a robot's explanation of its intended action.

Roboticists have developed many advanced systems over the past decade or so, yet most of these systems still require some degree of human supervision. Ideally, future robots should explore unknown environments autonomously and independently, continuously collecting data and learning from this data.

The system uses motors from the FAULHABER CR series, which has graphite commutation, a very robust type of commutation suited to high power applications. The motors also feature extremely powerful neodymium magnets and a high copper content rotor, delivering supreme power.

Researchers at Istituto Italiano di Tecnologia (IIT-Italian Institute of Technology) in Genova has realized a new soft robot inspired by the biology of earthworms,which is able to crawl thanks to soft actuators that elongate or squeeze, when air passes through them or is drawn out. The prototype has been described in the international journal Scientific Reports of the Nature Portfolio, and it is the starting point for developing devices for underground exploration, but also search and rescue operations in confined spaces and the exploration of other planets.

Nature offers many examples of animals, such as snakes, earthworms, snails, and caterpillars, which use both the flexibility of their bodies and the ability to generate physical travelling waves along the length of their body to move and explore different environments. Some of their movements are also similar to plant roots.

Taking inspiration from nature and, at the same time, revealing new biological phenomena while developing new technologies is the main goal of the BioInspired Soft robotics lab coordinated by Barbara Mazzolai, and this earthworm-like robot is the latest invention coming from her group.

The creation of earthworm-like robot was made possible through a thorough understanding and application of earthworm locomotion mechanics. They use alternating contractions of muscle layers to propel themselves both below and above the soil surface by generating retrograde peristaltic waves. The individual segments of their body (metameres) have a specific quantity of fluid that controls the internal pressure to exert forces, and perform independent, localized and variable movement patterns.

IIT researchers have studied the morphology of earthworms and have found a way to mimic their muscle movements, their constant volume coelomic chambers and the function of their bristle-like hairs (setae) by creating soft robotic solutions.

The team developed a peristaltic soft actuator (PSA) that implements the antagonistic muscle movements of earthworms; from a neutral position it elongates when air is pumped into it and compresses when air is extracted from it. The entire body of the robotic earthworm is made of five PSA modules in series, connected with interlinks. The current prototype is 45 cm long and weighs 605 grams.

Each actuator has an elastomeric skin that encapsulates a known amount of fluid, thus mimicking the constant volume of internal coelomic fluid in earthworms. The earthworm segment becomes shorter longitudinally and wider circumferentially and exerts radial forces as the longitudinal muscles of an individual constant volume chamber contract. Antagonistically, the segment becomes longer along the anterior–posterior axis and thinner circumferentially with the contraction of circumferential muscles, resulting in penetration forces along the axis.

Every single actuator demonstrates a maximum elongation of 10.97mm at 1 bar of positive pressure and a maximum compression of 11.13mm at 0.5 bar of negative pressure, unique in its ability to generate both longitudinal and radial forces in a single actuator module.

In order to propel the robot on a planar surface, small passive friction pads inspired by earthworms’ setae were attached to the ventral surface of the robot. The robot demonstrated improved locomotion with a speed of 1.35mm/s.

This study not only proposes a new method for developing a peristaltic earthworm-like soft robot but also provides a deeper understanding of locomotion from a bioinspired perspective in different environments. The potential applications for this technology are vast, including underground exploration, excavation, search and rescue operations in subterranean environments and the exploration of other planets. This bioinspired burrowing soft robot is a significant step forward in the field of soft robotics and opens the door for further advancements in the future.

Motion control systems with brushless DC, voice coil or three-phase direct drive actuators use a position servo controller that dynamically changes the current in each motor phase.

Robots are all around us, from drones filming videos in the sky to serving food in restaurants and diffusing bombs in emergencies. Slowly but surely, robots are improving the quality of human life by augmenting our abilities, freeing up time, and enhancing our personal safety and well-being. While existing robots are becoming more proficient with simple tasks, handling more complex requests will require more development in both mobility and intelligence.

Recently, a research team from Shenzhen Institute of Advanced Technology, Chinese Academy of Sciences, proposed a bionic quadruped soft thin-film microrobot actuated by magnetic fields with a mass of only 41 mg, which promises to be applied to stomach examination and treatment. Researchers realized the multimodal locomotion control of the soft microrobot in magnetic fields and the grasping and transportation of micro-objects by the soft microrobot.
