This document discusses nanorobotics and nanomanipulation. It defines nanorobotics as involving the design and control of robots at the nanoscale level, as well as manipulating nanoscale components with larger instruments. Some key points discussed include: - Nanorobots can be categorized as autonomous or insect-like robots, and they require little energy but can operate much faster than larger robots. - Fractal robots are made of motorized cubic blocks that can rearrange themselves under computer control to form different shapes. - One challenge is nanomanipulation and nanoassembly, which has been demonstrated by manipulating individual atoms. Nano tweezers are needed for reliable pick-and-place manipulation at the nanoscale.
Nanorobotics and nanomanipulation
- 1. Nanorobotics and Nanomanipulation Presented by ARAVINTH D MSc Nanoscience and Technology Alagappa University Karaikudi
- 2. Introduction to robotics • Like nanotechnology, Robotics is the use of technology to design and manufacture (intelligent) machines, built for specific purposes, programmed to perform specific tasks. • They range from small, miniature machines, to large crane size constructions
- 3. Introduction to Nanorobotics • nanorobotics can be generally divided into two main focus areas • The first area deals with the design, simulation, control, and coordination of robots with nanoscale dimensions • The second area deals with the manipulation and/or assembly of nanoscale components with macroscale instruments or robots • It is concerned with construction and programming of robots with overall dimensions at the nanoscale.
- 4. Features of Nanorobots • Nanorobots can be categorized into two groups called autonomous robots and insect robots. • A major asset of nanorobots is that they require very little energy to operate. • Durability is another potential asset, may remain operational for years, decades or centuries. • High speed is also a significant consideration. It can operate much faster than their larger counterparts.
- 5. Fractal Robots • Fractal robot is a new kind of robot made from motorized cubic bricks that move under computer control. • These cubic motorized bricks can be programmed to move and shuffle themselves to change shape to make objects likes a house potentially in a few seconds because of their motorized internal mechanisms.
- 6. Nanomanipulation • One of the biggest challenges in the field of nanotechnology is nanomanipulation and nanoassembly. • The first real example of nanomanipulation was demonstrated by Eigler and Schweizer (1990) who manipulated individual xenon atoms using a STM to form the name of their employer, “IBM”. Atomic manipulation is typically performed in an ultra-high vacuum (UHV) environment and at very low temperatures (~4 K) to prevent contamination and drift issues
- 7. Nano tweezers • To accomplish pick-and-place manipulation and assembly, a reliable method of gripping is required. • Gripping at the nanoscale is a challenge because it is difficult to control the balance of forces between the object, the surface, and the tool (gripper) where van der Waals and electrostatic forces may dominate.

- 9. Application of Nanorobotics • Emerging drug delivery application • Bio-medical application • Brain Aneurysm • Communication system • Military and space applications
