Image Image Image Image
Fig. 1 Various types of actuation and grasping mechanisms in soft robotic grippers. (a) Actuation mechanisms: (i) cable-driven, (ii) pneumatic, (iii) electroactive polymer-based, and (iv) thermoactive polymer-based gripper and (b) Grasping mechanisms: (i) multi-fingered, (ii) jamming, (iii) suction, and (iv) dry adhesion
Fig. 2 Different actuation mechanisms in soft grippers: (a) Cable-driven actuation, (b) Pneumatic-driven actuation, (c) Electro-active actuation featuring dielectric elastomer actuators (DEA) and ionic polymer-metal composites (IPMC), and (d) Thermo-active actuation using shape memory alloys (SMA) and shape memory polymers (SMP)
Fig. 3 Different grasping mechanisms in soft grippers: (a) Jamming type: (i) Schematic illustration of the jamming-type grasping mechanism, (ii) Influence of contact angle on geometric interlocking, (b) Suction type: (i) Schematic illustration of the suction-type grasping mechanism, (ii) Suction type gripper integrated with an electro-adhesion layer, and (c) Dry adhesive type: (i) Schematic illustration of the dry adhesive-type grasping process, (ii) Dry adhesive type gripper integrated with microscale adhesive structures
Fig. 4 Hybrid grippers combining various actuation methods and grasping types: Schematic illustrations of (a) a hybrid jamming gripper, (b) a hybrid suction gripper, and (c) a hybrid dry adhesive gripper
