small robots

A saildrone, an unmanned, hurricane-proof research vessel, has begun a roughly 22,000km circumnavigation of Antarctica, departing from Hobart. The voyage aims to gather climate science data from some of the world's most dangerous waters, where few crewed ships can operate. Observers are sharing the story, impressed that a small robotic craft is attempting a route that has tested even experienced sailors.

Tiny microcontroller chips, traditionally limited to simple embedded tasks, can now run a diffusion model for image generation and a compact 289-million-parameter large language model. The news, highlighted by Adafruit and Open Source For You, points to rapid progress in on-device AI, letting small, low-power hardware perform generative tasks without cloud servers. Enthusiasts are discussing what this means for smart devices, robotics and offline AI applications.

Researchers have developed a wind-up elastic robot that can keep jumping continuously when supplied with infrared light. The material converts the light into heat, re-tensioning its elastic body so the hopping cycle repeats without batteries or manual rewinding. The demonstration is drawing attention as a possible route to small, untethered soft robots for exploration or search tasks.

Engineers at the University of Washington have developed a tiny jumping robot capable of precisely controlling how high it leaps. The breakthrough could matter for applications where small robots need to navigate uneven terrain or obstacles, such as search-and-rescue or inspection tasks. Details of the mechanism behind the fine jump control have drawn attention across robotics news outlets.

Engineers at UC Davis have developed a tiny flying robot designed to survive collisions, a step toward taking such drones out of the laboratory and into real-world environments. The work, highlighted by the university's College of Engineering, focuses on durability so small aerial robots can operate around people, obstacles and unpredictable conditions outside controlled settings.

Engineers at UCLA have developed a small hopping robot that moves like a frog, using twisting elastic rods as its propulsion mechanism. The design stores energy in the elastic rods, which twist to launch the robot into jumps. The work points to new ways of building agile robots that can hop over obstacles where wheels or legs struggle.

Engineers at MIT have designed a small swimming robot propelled by living muscle cells, according to Forbes. The biohybrid device uses biological tissue as its power source rather than a conventional motor, pointing to a growing field of robotics that merges synthetic structures with living cells for soft, agile movement.

Researchers have developed a new propulsion method for small robots that uses low-power twisting movements, allowing them to hop and swim without large amounts of energy. The approach could make miniature robots more practical by reducing power demands while keeping them mobile across different environments.

Researchers at the Singapore University of Technology and Design have developed a small robot that descends by spinning like a falling maple seed and can then move across water like a boat. The dual-mode design suggests potential uses for distributing sensors or payloads from the air and continuing operations on water. The work was announced via science news services EurekAlert and Asia Research News.

Radiosol, a post-apocalyptic game about surviving alongside robots, launched on Steam this week. An account of a player's first 30 minutes resonated with readers, and several of them went on to buy the game after reading it. The early buzz suggests personal stories are proving an effective way for small releases to find an audience.

The City of Taylor, Texas has asked residents to help come up with names for the robots it uses at its cemetery. The machines handle maintenance work on the grounds, and the city is turning the naming into a public participation effort. The lighthearted request has drawn attention as an example of small-town government embracing automation with a sense of humor.
