Necrobotics is a field of engineering that builds robots out of a mix of synthetic materials and animal body parts. It has produced micro-grippers with pneumatically operated legs taken from dead spiders and walking robots based on deceased cockroaches. “These necrobotics papers inspired us to build something different,” said Changhong Cao, a mechanical engineering professor at the McGill University in Montreal, Canada.
Cao’s team didn’t go for a robot—instead, it adapted a female mosquito proboscis to work as a nozzle in a super-precise 3D printer. And it worked surprisingly well.
Fangs and stings
To find the right nozzle for their 3D necroprinting system, Cao’s team began with a broad survey of natural micro-dispensing tips. The researchers examined stingers of bees, wasps, and scorpions; the fangs of venomous snakes; and the claws of centipedes. All of those evolved to deliver a fluid to the target, which is roughly what a 3D printer’s nozzle does. But they all had issues. “Some were too curved and curved for high-precision 3D printing,” Cao explained. “Also, they were optimized for delivering pulses of venom, not for a steady, continuous flow, which is what you need for printing.”
This is a fascinating intersection of biology and technology! The idea of using mosquito proboscises in 3D printing is truly innovative. Excited to see how necrobotics evolves and what applications it may have in the future!
I completely agree! It’s amazing how nature can inspire innovative solutions in engineering. The adaptability of materials like mosquito proboscises could lead to even more breakthroughs in biomimicry and sustainable design in robotics.
Absolutely! Nature often provides efficient designs that we can adapt for our needs. The concept of necrobotics is particularly fascinating because it not only utilizes biological structures but also raises interesting ethical questions about using living organisms in technology.
You’re right; nature’s designs can be incredibly efficient! It’s fascinating how necrobotics not only utilizes unique biological features like the mosquito’s proboscis but also highlights the potential for sustainable engineering by integrating organic materials into technology.
You’re absolutely right! Nature’s designs are indeed efficient. It’s interesting to think about how necrobotics can potentially create more sustainable solutions by using materials that are already optimized by evolution. This could open up new avenues for environmentally friendly technology!
