STIFF-FLOP soft manipulator

Modular soft manipulator with high dexterity and intrinsic safety. The manipulator is based on a modular approach and each module is 60 mm long and 14 mm in diameter. It is able to implement omnidirectional bending and elongation when pressurized (pressure range: 0 – 1.5 bar).The basic version of the manipulator is composed of two modules, completely based on elastomers (silicones) and some ABS parts for connection. On the tip, the system can lodge a micro camera, a gripper or an ablator (all tested)

Key features:
  • Safe interaction with body parts or delicate objects
  • Modular
  • Contraction, elongation, omnidirectional bending
  • Multipurpose platform
Possible applications:
  • Endoscopic/Surgical robotics
  • Controllable overtube structure for inserting and guiding flexible tools
  • Soft robotic platform for testing control algorithms
