It seems engineers have finally found a way to rid humanity of one of the main problems of modern technology β endlessly charging batteries!
Researchers at Delft University of Technology in the Netherlands have developed an unusual experimental robotic gripper that uses living microalgae.
Yes, yes, you heard that right. Instead of the usual motors and mechanical drives β tiny living organisms!
Now imagine that your robot assistant, instead of the usual "Battery low," one day announces:
"Sorry, it's cloudy today. I'm not in the mood to work!" π
The robot itself is quite small β its flexible working part is about two centimeters long.
But what matters here is not the size, but the principle of operation.
The scientists created a thin, flexible structure in which living microalgae help the material respond to changes in the surrounding conditions related to lighting.
When these conditions change, the strip bends and can grasp small objects.
The result is something between a plant and a mechanical hand.
Only a plant usually sits quietly on a windowsill, while this little one is already trying to work!
It seems evolution has reached the robotics department and declared: "Let me try too!" π
πΏ Why did robots need algae?
Today most robots use electric motors, batteries, pumps or complex control systems.
But engineers are increasingly exploring so-called soft robotics β devices capable of moving and changing shape thanks to flexible materials.
Particularly interesting are structures that respond to the external environment without bulky mechanisms.
Living cells can give materials unusual properties. Such systems could potentially be useful for miniature grippers, sensors and other devices that do not require great mechanical force.
Of course, a robot that independently cleans the apartment, makes breakfast and walks the dog is still very far away.
But the very idea looks amazing!
Imagine the office of the future.
Employees are working at their computers, and in the corner stands a robot with algae.
Suddenly a cloud appears outside the window.
The robot stops moving.
The boss asks indignantly:
β Why has the work stopped?
β Our sun has gone away.
β Then turn on the lamp!
β The lamp is on vacation today! π
βοΈ Will the robots of the future demand vacations at sunny resorts?
For now this is only a laboratory experiment, and it would be premature to talk about a full-fledged autonomous robot powered by solar energy.
But the direction of research is truly curious.
Perhaps over time living materials will help create more compact devices that will not need traditional motors for every movement.
And such developments also make us take a new look at the boundary between living nature and technology.
After all, before, we imagined a robot as a metal creature with wires, motors and batteries.
And now it turns out that some mechanical functions can be entrusted to living organisms.
And it seems that soon the engineering manual will begin with the words: βDo not forget to water your robot and provide it with good lighting!β π
True, this kind of technology has one potential advantage over ordinary machines.
If a robot really learns to use living systems effectively, it may need fewer complex mechanical components.
But there is also a new concern: living cells need suitable conditions.
That is, an ordinary robot requires maintenance.
And this one may also require a caring gardener!
The main thing is not to get confused and send it to spend the winter along with the houseplants.
And yet the experiment by the Dutch scientists shows perfectly well how unexpected the paths of technological development can be.
Perhaps the future of robotics will be not only metal and electronic, but also green, flexible and even a little alive.
And for now, while humanity awaits robots that will work instead of us, scientists have created the first candidate that also needs a good sunny day! π±π
