Nature-inspired gripper! 🦎
A chameleon doesn't grab its prey, but its tongue wraps around it.
Festo built a gripper that does the same thing, and the mechanism is more elegant than it looks.
The FlexShapeGripper is an elastic silicone cap sitting on a water-filled chamber. It works as a double-acting cylinder, one chamber holds compressed air, the other is permanently filled with water.
Vent the air chamber, and the water-filled silicone pulls itself inwards. The cap folds over whatever is underneath and locks around its shape.
The grip is form-locking, so the object's own geometry does the work of holding it.
→ Adapts to any shape, including delicate and irregularly shaped items where rigid jaws fail
→ Can pick up and deposit several objects in one operation
→ Pneumatic drive, minimal energy consumption
→ The silicone cap maps directly onto the chameleon's tongue
Always good to see the mimicry developments from Festo! :)
