Adaptive
Fin Ray fingers from Festo can grip differently shaped and also very sensitive objects without additional sensor or control technology.
Three to four anal
fin rays appeared, and anal and dorsal
fin ray buds were observed (Fig.
The
fin ray DEC collected from her put her age at 84 years old.
Each tentacle is formed as a structure which demonstrates what is known as the
Fin Ray Effect.
"The MultiChoiceGripper combines two development fields--adaptive finger technology using Festo's
Fin Ray structures and a mechanical linkage that changes the position of the fingers from 'opposing' to 'surrounding'."
Principal component and/or discriminant functions revealed that meristic characters were highly correlated with pectoral
fin ray count, number of lateral line scales, as well as number of anal
fin rays.
For example, Maraldo and MacCrimmon (15) found that dorsal fin spine and pectoral
fin ray cross sections were unreliable for aging largemouth bass from northern waters.
Chen and Yang (2004) described Tor genus with following characters: lower lip developed into fleshy lobe, or at least with two notches delimiting the usual position of the lobe; post labial groove uninterrupted; last simple dorsal
fin ray osseous and non-serrated; no forward directed pre dorsal procumbent spine; no groove in front of nostrils.
Total length (TL) of each fish was measured from the tip of snout to the longest
fin ray of the caudal fin (in mm).
Posterior hoxa genes expression during zebrafish bony
fin ray development and regeneration suggests their involvement in scleroblast differentiation.

The key to FinGripper's performance is the "
Fin Ray" structure of its three "fingers," which move like the flexible tail of a fish.
