POWER SOURCES IN NANO ROBOTS

There are mainly two power sources used for nanorobots internal power sources and external power sources.

1. Internal Power Sources

A nanorobot could use the patient's body heat to create power, but there would need to be a gradient of temperatures to manage it. Power generation would be a result of the See beck effect. Capacitor which has a slightly better power-to-weight ratio can also used.

• External Power Sources

External power sources include systems where the nanorobot is either tethered to the outside world or is controlled without a physical tether. Tethered systems would need a wire between the nanorobot and the power source. The wire would need to be strong, but it would also need to move effortlessly through the human body without causing damage. A physical tether could supply power either by electricity or optically. Experimenting with in Montreal, can either manipulate the nanorobot directly or induce an electrical current in a closed conducting loop in the robot.

•  Procedure

The basic idea behind nanorobotics is to manipulate objects at scale of nanometers. Nanorobots might function at the atomic or molecular level to build devices, machines, or circuits, a process known as molecular manufacturing.
There are basically two approaches followed in implementing nanorobots:
The first approach is biochip which provides a possible approach to manufacturing nanorobots for common medical applications, such as for surgical instrumentation, diagnosis and drug delivery. This method for manufacturing on nanotechnology scale is currently in use in the electronics industry. So, practical nanorobots should be integrated as nanoelectronics devices, which will allow tele-operation and advanced capabilities for medical instrumentation.

2. The second approach is self reconfigurable modular robots also known as Fractal robots. Self-reconfiguring robots are also able to deliberately change their own shape by rearranging the connectivity of their parts, in order to adapt to new circumstances, perform new tasks, or recover from damage
