7. Nanorobotics
• Nanorobotics is the technology of creating machines or robots at or close to
the microscopic scale of a nanometre.
• Nanorobotics is the tiny machine designed to perform a specific task whose
components are at or close to the scale of a nanometer.
• The main element used will be carbon in the form of diamond nanocomposites
because of the strength and chemical inertness of these forms.
• Nanorobot also called as Nanobots , Nonoids, Nanites , Nanomachines or
Nanomites.

surfaces through ultrasound, pH changes, and specific protein structures through
functionalized surface probes would provide useful feedback data.

14. Sensors Uses in Nanorobot
Proximity Sensor
Range Sensor
Tactile Sensors

15. Sensors Uses in Nanorobot
Proximity Sensor
• A proximity sensor is a sensor able to detect the presence of nearby
objects without any physical contact.
• A proximity sensor often emits an electromagnetic field or a beam of
electromagnetic radiation (infrared, for instance), and looks for
changes in the field or return signal.

16. Sensors Uses in Nanorobot
Range Sensor
• Range Sensor is implemented in the end effector of a robot to
calculate the distance between the sensor and a work part.
• The values for the distance can be given by the workers on visual
data. It can evaluate the size of images and analysis of common
objects.
• The range is measured using the Sonar receivers & transmitters or
two TV cameras.

17. Sensors Uses in Nanorobot

18. Sensors Uses in Nanorobot
Force Sensor

functions like the machine loading & unloading performed by a
robot.
• This sensor will also be a better one in the assembly process for
checking the problems.
• There are several techniques used in this sensor like Joint Sensing,
Robot – Wrist Force Sensing, and Tactile Array Sensing.

19. Sensors Uses in Nanorobot
Cantilever Sensor

20. Sensors Uses in Nanorobot
Tactile Pressure Sensor
• A tactile sensor is a device that measures the force and pressure
applied between the sensor and an object.
• Tactile sensors are composed of two thin, flexible substrates that
have electrically conductive materials deposited in rows and
columns. A layer of pressure-sensitive material is applied to the
inner surface of each of the intersecting conductive layers.

25. Actuators
What is Actuator?
• Actuation is the process of conversion of energy to mechanical form. A device that
accomplishes this conversion is called actuator.
• Actuator plays a very important role while implementing control. The controller
provides command signal to the actuator for actuation.
• The control codes aims at “deriving the actuator when an event has occurred”
Role of Actuator in Robotics?
• Actuators are used in order to produce mechanical movement in robots.
• Actuators are the muscles of robots. There are many types of actuators available
depending on the load involved. The term load is associated with many factors
including force, torque, speed of operation, accuracy, precision and power
consumption.

26. Actuators (Mover) for Nanorobotics
• Piezoelectric materials have been used as actuators or sensors in bulk or thin film
forms.
• Nanoscale piezoelectric materials can generate voltages under the peristaltic action
of the gastrointestinal tract and convert mechanical energy into electrical energy.
This could be one solution to the power and propulsion subsystem.
(Feng et al .,2015)

27. Bio-Nano actuator
• The classical actin-myosin power stroke that converts chemical energy of ATP to
mechanical work of muscle is probably the oldest known.
• More recently, the microtubule motor protein families kinesins and dyneins have
been identified.
• The kinesins constitute a superfamily of protein motors similar in structure to
myosin that are involved in motion of the cytoskeleton of cells.
(Mojaraat et al .,2017)

29. Power supply of Nanorobotics
• Rechargeable thin-film batteries enable the use of arbitrarily shaped batteries with
thickness less than 50 nm , and have been used in micro-robotic applications.
• Vibration, thermal gradients. The transmitted power uses magnetic fields to induce
electricity wirelessly, where the human body is ‘‘transparent’’ to magnetic fields .

the end-effector is not exactly pushing on the particle center.
