Soft Pneumatic Gripper vs. Rigid Jaw

Compare a soft pneumatic bellows gripper that passively conforms to any object's shape against a rigid parallel-jaw gripper that needs a precisely computed gap for every object, or it drops or crushes what it's holding.

Pick one of three objects — a plain sphere, an irregular star-shaped blob, or a fragile thin wafer — then try to pick it up with two very different grippers. The soft gripper's three bellows fingers curl closed as internal air pressure rises, passively conforming to whatever shape is underneath them. The rigid parallel-jaw gripper instead needs its jaw gap set by hand for each object: get it wrong and the object slips out or, for the wafer, gets crushed. The results table on the left fills in live as you test every object against both gripper types.

⚙ Under the hood

Grasp a sphere, an irregular star and a fragile wafer with a soft pneumatic bellows gripper that passively conforms to whatever shape it meets as air pressure inflates its three fingers, then compare against a rigid parallel-jaw gripper that needs its gap precisely set for every object or it drops or crushes what it's holding. A live 3x2 results table tracks grasp success across all objects and both gripper types.
