DESCRIPTION
The ‘microbot’ is acronym for ‘microscopic robot’. Blending biological, mechanical and electronic systems(sub-systems) with phenomenal precision as well as accuracy, microbot is a fully integrated sophisticated system, blurring the lines between men and machines and transforming fiction into reality. The microbotics technology is conglomeration of micro-electro-mechanical-system (MEMS), embedded and biological systems. Typical components in a microbot are extremeties (e.g. wheels, arms, aerodynamic structure to provide mobility), sensors (e.g. to capture information), body (i.e. the framework that gives weight and stability), brain (e.g. to control and coordinate) and payload (i.e. drugs for specific healing purpose). One of the critical areas in developing microbots is to provide power supply or to energize the moving or rotating parts and shape/size of microbots. There are various ways to energize. The microbots can use a small lightweight battery source or can scavenge power from the surrounding environment in the form of vibration or light energy or use biological motors to draw chemical power from the surrounding fluid to actuate the robotic device.

Criticalities and Conclusion
Major Criticalities: o To achieve microbots of few micron sizeo Steering mechanism for such a small size
There are so many Unanswered Questions!H i b t d d t d li h d t
o Steering mechanism for such a small size.
o How many micrbots are needed to deliver enough drugs to kill a tumor?o What amount of bacteria is safe to inject in humans? o Will the body raise antibodies against them?
Still, we need to wander with a big hope that onedaymicrobot will contribute heavily and successfully to
their journey on Medical Mission!t e jou ey o ed ca ss o !
