A team of engineers from China and the US has built the world’s smallest remote-controlled walking robot. Its size is only half a millimeter, and in its appearance it resembles a crab.

Such tiny robots have a range of potential applications, from assisting in surgical operations (for example, to remove blood clots or tumors) to repairing various equipment in hard-to-reach places. And the smaller the robots, the more scenarios for their use.

Although the robot shown in the picture does not yet have a specific application, the methods on the basis of which it is developed may serve in the future to create tiny robots in almost any desired configuration. “Our technology provides various ways of controlled movement, the robot can move at an average speed equal to half its body length per second.”said mechanical engineer Huang Yonggang of Northwestern University in Illinois.

The technology for manufacturing such robots was developed eight years ago: individual parts of the robot are mounted on an elastic substrate with shape memory, which takes one of two positions depending on the degree of heating. The lasers, acting as a kind of remote control, sequentially heat certain parts of the robot, as a result of which these parts take the desired shape and push the “crab” forward. There is no need for an additional power supply or motors, and the thin transparent layer ensures that the components return to their original shape when cooled extremely quickly due to the tiny size of the device. By aiming lasers at different parts of the robocrab, researchers can set one or another direction of movement, and by adjusting the frequency of laser flashes, you can change the speed of the robot.

Mercedes Benz will stop producing A Class and B Class models

German publication Handelsblatt reports that Mercedes will cease production of A-Class and B-Class vehicles after the end of production of the current generation in 2025. The news comes weeks after Mercedes announced it was cutting its entry-level lineup from seven body styles to four in a bid to push its way into a higher market.

The source writes that members of the board of directors of Mercedes have already decided to abandon the successor to the A-class. The more practical and less popular sister B-class minivan will also go down in history. However, the current generation of the A-Class and B-Class are getting mid-life updates this year that will extend their life cycles into 2025.

That being said, Mercedes officials have reportedly given the green light to successors to other compact models. These include the CLA, likely in both four-door coupe and five-door Shooting Brake body styles, as well as the GLA/EQA and GLB/EQB SUVs.

It was decided to reduce the line of compact cars and rename it to Entry Luxury. It will be based on the new MMA architecture, bringing better equipment and more technology to the compact segment. The platform is designed primarily for electric vehicles, but also supports hybrid powertrains. One of the features of the new cars on the MMA platform will be the proprietary infotainment system MB.OS. It will debut in 2024 at the same time as the first production model based on MMA.
