Designing with Pneumatics-Catcher

As a general rule, if you are designing a system that demands forces other than along the the push/pull line of action, other components of the system need to handle those besides the pneumatic pistons themselves.

A go-to mechanism I always prefer is cascading drawer sliders, you can get these in oodles of lengths and loading capacities, with compact, reliable, and robust construction, and they sell them at Home Depot and Lowe's, or lots of places online

Good thing you guys got to us before we built this thing, I was quite afraid of this.

Another resource to look at if you haven't seen it already: the Build Blitz claw design guide has some great information.

takes after its shape actually, however we feel pneumatics might be a more versatile option given that we do not have accurate machining capabilities.
