Microrobots are being design roughly in the size range single to hundreds of mm, and being dominated by micro-scale physical forces and effects; contrasting milli-scale robots can be visible by human eye.
Primary uses in Medical applications.
Type of micro actuators
Different techniques can be uses to power micro-robots, the most successful is the principle of magnetic actuation is to propel micro-robots with magnetic forces and/or torques.
