are known to have optimum accuracy and repeatability when performing z-axis moves, because all links perform the same motion at the same relative link angle,' explained Nathan Brown, vice president of engineering at Alio Industries.
In order to achieve precision at the micron and sub-micron level in multi-axis motion applications, hexapod
parallel positioners have become popular.
The equipment used to simultaneously excite MDOF can be separated into two generic types--orthogonal and hexapod
. The MTS Systems Model 323 system being used to test automotive components in Figure 1 can provide true 6DOF vibration.

we chose being the property of Arts et Metiers ParisTech - campus of Bordeaux-Talence (ENSAM Bordeaux-Talence), we verified that the profiles were within the maximum displacement (+/-40cm) and the maximum accelerations (+/-1G).
Over the last decade, the hexapods
have been introduced and embraced by the Trauma and Limb Lengthening communities.
Thus, a hexapod
robot will have 15 degrees of freedom unlike insects, which have at least 18 degrees of freedom.
, also known as a Stewart platform or Gough/Stewart platform, is a six-legged parallel mechanism structure.
In order to extend the mobility of a single hexapod
, a structure with two staged modules was proposed, as in Fig.
There are about 38,000 species of described Mexican arachnids and hexapods
, although several taxa have not been reviewed yet.
Prey: (1= annelids and Molluscs; 2= arachnids and myriapods; 3= hexapods
; 4= fishes; 5= amphibians (Anurans and Caecilians); 6= reptiles (Lizards and snakes); 7= Birds (adults, nestlings and eggs); 8= Mammals (rodents, bats & large mammals).
Hennessey spent a year developing next-generation "hexapod
" robots, and now has a pair of patents to show for it.
