Micro and Nano Robots

The first generation of Small-Scale robots are generally referred to as "micro/Nano motors" or "micro/Nano engines" by researchers in the micro/nano robotics field, which are described as small scale devices capable of converting a variety of energy sources into locomotion or actuation. A micro/Nano robot, on the other hand, is a small scale device capable of mechanical actuation to fulfil a preprogramed task. It's been difficult to define what constitutes a micro/Nano robot because small-scale robotic designs differ significantly from their macroscale equivalents. When a new study subfield emerges from an established topic, its success is usually measured in terms of what it isn't rather than what it is. Automobiles, for example, were dubbed "horseless carriages" when they first appeared on the streets more than a century ago. When compared to internal combustion engines, electric motors, or hydraulic and pneumatic systems, the design of tiny size robots presents unique obstacles. Viscous forces dominate inertial forces at tiny scales. Environmental influences such as Brownian motion, which is induced by random collisions of water molecules with micro scale objects and interferes with the directionality of a motile micro/Nano robot, must be considered when designing structures at such a small scale.
