Mouth-Like Hands Allow The FlexShapeGripper Robot To Grab And Grip A Wide Variety Of Objects

Having five fingers allow us to grab, grip, and hold on to objects unlike any other creature on the planet. And while it’s logical to want to give gripper robots the same five-digit benefits, it’s not easy, with most implementations using multiple motors to coordinate a single finger alone. That’s why, rather than emulating the human hand, the FlexShapeGripper robot uses an entirely different mechanism.

Made by Festo, the robot hand draws inspiration from the chameleon, whose tongue catches insects by laying on top of the bug and securely wrapping around it. Instead of a tongue, though, it uses a silicone balloon cast in a round mouth shape that fills up with air and water to grab onto objects and wrap itself around them.

The FlexShapeGripper’s silicone “hand” comes with pressurized dual chambers, one of which is permanently filled with water and another that fills up with varying amounts of gas, depending on what kind of object is being picked up. Since the silicone can deform at will, it can accommodate any shape, affording it the gripping power to pick up everything from cords to mugs to ball-bearings to pens to eyeglasses to multiple items at the same time. Even better, it retains shape when powered off, so it doesn’t need to use electricity while maintaining its grasp. Both the gripping and releasing actions are accomplished pneumatically, so it’s as gentle when letting items go as it is when picking them up.

    That is pretty cool. I am not finding any sort of use for it at home, but for small industry type business, it might make sense.

    This is very neat and impressive! What’s the starting-price? I really like this, because my Mom and Grandmom are always relying on the Gopher Grabbers to pick things up for them, etc. and these are often prone to breakage, and an overall lack of mobility and flexibility. I’d be willing to put out $150-$200 for this, barring it comes with a good warranty and quality Customer Service. If they’re willing to stand behind the product, then I’m willing to give it a shot!
