Its’s a laser cut arm structure, operated by servos and a 3D printed hand or grabbing device that will work as a soft robotics skeleton within a vacuum bag. The principle is that anything inside a vacuum bag that had indentations that can act as mountains and valleys is done in origami, when the air is removed from the bag that contains it, it will be forced to contract to its fullest in whatever direction it’s set. All the parts that are needed are cut out on 3mm acrylic with some minor modifications. If you build a bigger box you will be able to fit the vacuum pump that will be extracting the air of a vinyl bag that will contain the 3D printed “skeleton” that will allow the contracting movement of the soft robotics. In this project the claw component is removed as well as any parts that are needed for component since it’s replaced by the soft robotics hand.
I call it a “hand” but I suppose ‘grip’ might be more accurate since the shape of the gripping device isn’t necessarily shaped like a hand.
