Improvement of detachable actuator for wall climbing

As a dismantle-able adhesion method using induction heating and thermoplastic adhesive, the allover method has been proposed for interior constructions. The method is able to bond and dismantle many times. In the previous paper, we have proposed a unique detachable actuator for wall climbing. It was able to attach and detach from any wall applying the allover method. But the reliable bonding strength to a wall was unsatisfied to sustain a total human weight on 70kg. In this paper, improvement for a large bonding strength with addition of two induction coils and for an actuator's structure and its behavior are described.
