It is a 3D printed Conforming Gripper actuated by a 3D printed linear actuator, controlled locally or remotely
The basic idea is to promote 3D printers as standard equipment aboard a Space station.
This way anything that gets broken can be easily replaced..... even designed by someone back at Houston... then beaming the STL file to be printed at the space station.
Also each Astronaut will have in his/her pocket a number of FPGA chips .... as they are like Programmable circuits capable of running systems in parallel.
All the 3D print STL files are already available as Open source ....links in the description.
