Imagine microrobots in water, not just moving but actually talking to each other—no external controls, just light pulses and onboard logic. These new 'smartlets' can sense, communicate, and collaborate autonomously, opening up possibilities from medical diagnostics to environmental monitoring. But as these robotic colonies get smarter and more independent, are we ready for the security and ethical questions they raise? How far should we let distributed intelligence go? #Tech #microrobots #swarmtech
