One of the tools we worked with yesterday in the pool with Terry is the APFR – Articulating Portable Foot Restraint.
You can take a look at one in the picture I attached. As you can see, you can slide your boots in there: it takes a deliberate rotation of the heels to make or release the connection, so once you’re in you have a rigid attachment point to structure. That’s really useful when you need to work for a long time at a worksite, especially if the worksite doesn’t provide a lot of handrails or if you need to react big loads (like releasing a bolt that was fastened at a high torque).
APFRs have three articulating joints to adjust pitch, roll and yaw. They are attached to structures via WIFs, which are available on structure throughout Station. The clocking of the APFR in the WIF (how it is rotated with respect to a reference line) gives you an extra adjustment opportunity for the orientation.
And of course when a crewmember needs to work on the robotic arm we can attach an APFR on the arm end effector.
