Inspired by Frogs and Turtles
Researchers at the University of Washington have engineered a small jumping robot named DirectHop, roughly the size of a human palm. This innovative device can leap over steps, right itself after falling, and navigate complex obstacles—all without relying on springs. Its movements mimic the muscle action of a frog, while its protective outer shell is modeled after the box turtle’s carapace. Powered via wired connection, DirectHop is expected to cost around ten dollars per unit when mass-produced.
Key Features of the Jumping Robot
The robot uses an electric motor that pulls a line to launch it upward. While airborne, it maintains stability using three foldable legs. One standout capability is its ability to self-roll onto a supporting leg after a fall in 90% of cases. Although the current prototype cannot choose its direction independently, future versions are planned to include cameras, solar panels, and vibration motors to enable turning.
'The small motor can accelerate as quickly as frog leg muscles, and by adjusting the current, we can control the jump height with centimeter precision.'

Soer Fuller added that 'the most challenging aspects for these machines have always been adjusting jump length, standing up independently, and being ready for the next leap.'
This cutting-edge robot has potential applications in reconnaissance at oil refineries, farms, and even on the surfaces of other planets. The news was published on September 28 at 09:06.
Developing robots inspired by biological systems paves the way for their use in environments that are difficult for conventional technology. For instance, deploying such robots at oil facilities can simplify tasks in hard-to-reach areas, while adapting them for space missions could open up new possibilities for planetary exploration. Importantly, the decreasing production costs make these advanced robots more accessible, encouraging broader adoption across various industries.
As robotics continues to evolve, innovations like DirectHop highlight the potential for machines to perform complex tasks in challenging environments. For example, a recently developed palm-sized robot that excels at jumping, climbing, and swimming showcases the versatility of small robots powered by elastic limbs. Such advancements may inspire further research and development in the field, leading to even more sophisticated applications in diverse settings.
