▎ 摘　　要

NOVELTY - Robot has a shell formed with an opening. The shell is provided with a carbon nano material inner shell and a permanent magnetic shell. The permanent magnetic shell is arranged on an outer side of the carbon nano material inner shell. The carbon nano material inner shell is provided with a carbon nano material outer shell. the material of the inner shell of the carbon nano material is graphene-carbon nano tube composite material or graphene oxide-carbon nano tube composite material. the thickness of the inner shell of the carbon nano material is 20 to 50nm; the thickness of the permanent magnetic shell is 0.5 to 5nm, material of the permanent magnetic shell is ferroferric oxide. USE - The shell type nano robot is useful for loading medicine and other active components. ADVANTAGE - The robot: improves load quantity; has magnetism; can move under the action of the external magnetic field; solves the nano robot power shortage, moving speed and the difficult direction to control. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing shell-type nano robot comprising (a) providing a convex mold, where the convex surface is provided with a carbon nano material film layer, (b) plating a permanent magnetic material on the surface of the carbon nano material film layer, forming a permanent magnetic film layer, (c) stripping the multilayer composite material obtained in the step (b) from the mold. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the shell type nano robot for loading medicine and other active components.
