Legged walking and climbing robots have recently achieved important results and developments, but they still need further improvement and study. As demonstrated by recent works, bio-mimesis can lead to important technical solutions in order to achieve efficient systems able to climb, walk, fly or swim (Saunders et al., 2006 [36], Ayers, 2001 [25], Safak and Adams, 2002 [26]). In this paper, taking into account the anatomy and the adhesive and locomotion capabilities of the spider (i.e., an eight-legged system), we present on the one hand a study of the foot force and torque distribution in different operative and slope conditions and, on the other hand, a posture evaluation by comparing different leg configurations in order to minimize the torque effort requirements.

Abstract
Legged walking and climbing robots have recently achieved important results and developments, but they still need further improvement and study. As demonstrated by recent works, bio-mimesis can lead to important technical solutions in order to achieve efficient systems able to climb, walk, fly or swim (Saunders et al., 2006 [36], Ayers, 2001 [25], Safak and Adams, 2002 [26]). In this paper, taking into account the anatomy and the adhesive and locomotion capabilities of the spider (i.e., an eight-legged system), we present on the one hand a study of the foot force and torque distribution in different operative and slope conditions and, on the other hand, a posture evaluation by comparing different leg configurations in order to minimize the torque effort requirements.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
