Please, for this application you should use the term, "gripping hand".
To be more substantive: now you mention it I haven't heard of such a device and I also wonder why. Makes sense for inspection (but how much happens?) though retrieving lost tools sound quite difficult.
And though difficult, it seems like something worth becoming good at. Seems like a 1U might be big enough to hold a small drone and some things to retrieve. However you'd have to design your experiment carefully so that something you failed to retrieve would rather soon reenter the atmosphere and not become dangerous orbiting junk. I don't know how easy this would be: what if the drone tried to grab it and added a non-normal (i.e. sideways) component that put the target on a potentially destructive trajectory?
- ccooffee 3y agoAside: does the phrase "grasping hand" have a particular meaning in robotics jargon? (Or is there a different reason to avoid that terminology?) To me a "gripping hand" is intuitively something that continuously holds an item. It might require human intervention to work, such as positioning my camera onto a universal tripod mount. A "grasping hand" (or "grabbing hand") would be something that transitions from empty-handed to holding an item.
- r2_pilot 3y agoIn this case the GP is making a reference to "The Mote in God's Eye". An alien species has 2 hands that are similar to humans, but they also have a 3rd arm, which leads them to say, paraphrased, "on the one hand, on the other hand, on the gripping hand" since it's strongest.
