AI Technical Summary
Miniature wall-climbing robots have insufficient power density and extremely low motion frequency at the centimeter-millimeter scale. Their complex systems make it difficult to achieve wirelessly controllable motion, which limits their range of activity and operational flexibility. In particular, magnetic vertical wall-climbing robots are difficult to miniaturize.
The miniature wall-climbing structure, which adopts a flexible joint design, combines electromagnetic drive and shape memory alloy drive components. It generates electromagnetic attraction and repulsion forces through the alternating magnetic field of hollow coils and permanent magnets to achieve reciprocating vibration. The direction of the wall-climbing structure is controlled by the energized contraction of the shape memory alloy drive components, and a wireless communication module is integrated to achieve precise control.
Without increasing system mass and complexity, high-speed climbing and precise steering of a micro-climbing structure at the centimeter level were achieved, improving the robot's operational flexibility and reliability.
