The phrase "adhesion requirements" is correct and usable in written English.
It can be used in contexts related to materials science, engineering, or any field where the properties of adhesion are relevant, such as in manufacturing or construction.
Example: "Before proceeding with the assembly, we must ensure that all adhesion requirements are met to guarantee the integrity of the final product."
Alternatives: "bonding criteria" or "adhesive standards".
Specifically, the optimal configuration is considered to be the one that minimizes the adhesion requirements for the robot, that is minimizes the minimum of the maximum adhesion force of any foot.
The structural model used to investigate the effect of the different parameters on the adhesion requirements is used also to explain the positioning of the tip of the middle leg the ants use to stand on vertical surfaces; the stance that ants use minimizes the maximum adhesion force over the full range of the middle leg's tip position.
A number of parameters, namely the height of the robot, the length of its body and the position of its legs, are investigated to assess their effect on the adhesion requirements needed for the robot to stay attached to a wall.
Amplification of FAK signaling (and accompanying autoactivation) in cancer cells (Gabarra-Niecko et al., 2003; Mitra and Schlaepfer, 2006; Zhao and Guan, 2009), may provide an opportunity to bypass adhesion requirements and enhance metastatic potential, at least in part by relieving this repression.
Lower height to length ratio results in lower adhesion requirement, while higher cross-sectional area also results in lower adhesion requirement.
Fig. 13 The adhesion requirement for different middle leg's coxa and tips positions.
It, therefore, represents the maximum normal adhesion requirement for each position of the middle leg's tip.
Depending on the height to length ratio, tilting the body mostly improves the adhesion requirement for the robot.
From Fig. 8, the backward inclination of the legs improves the adhesion requirement when the middle leg's position is below 0.38 (see red circle in Fig. 8b).
In fact, in Fig. 6, a small variation of the leg from its optimal position causes the maximum adhesion requirement to increase dramatically.
In this work, an investigation of the effect of the inclination of the body and legs on the minimal adhesion requirement for a climbing robot to adhere to a vertical surface is investigated.
