What are the challenges in developing autonomous controls for nanobots?

The techniques used in creating the world's smallest walking robot can be applied to the development of nanobots by scaling down the technology. The smallest walking robot operates autonomously with an onboard circuit and no external controls. This is a significant achievement that can be applied to nanobots. However, the challenge lies in printing these techniques at a nanoscale, which is much smaller than the current microscale. This would involve advancements in nanotechnology and manufacturing processes.

Developing controls for autonomous nanobots presents several challenges. Firstly, the size of nanobots makes it difficult to incorporate complex control systems. Secondly, the autonomous operation of nanobots requires advanced algorithms and programming to ensure they can perform tasks independently. Thirdly, power supply for these nanobots is another challenge as traditional power sources are too large. Lastly, the ability to communicate with these nanobots and control them remotely is a significant challenge due to their size and the potential for signal interference at such small scales.
