Manipulator Foot Restraint
The Manipulator Foot Restraint (MFR) (sometimes referred to as Mobile Foot Restraint ) was a work platform that could be attached to the robot arm (RMS) of the space shuttle . It enabled a spaceman , during a spacewalk to move freely without having to hold on to. The astronaut was fixed with footrests.
The basis of the MFR was an aluminum tube about two and a half meters long. A standard coupling mechanism for the RMS was located on the lower part of the MFR (1.33 m long, including the 20 cm long "RMS spike"). Above it was a footrest with two holders for the astronaut's shoes. In front of the footplate (37 cm deep, 52 cm wide), the MFR post was fitted with a hinge. This enabled the platform to be folded up for transport. The upper part of the MFR was provided with a 63 cm wide handle and provided space for tools. It was 1.20 m long up to the hinge and could be rotated 180 ° to the left and right. In addition, the upper post could be tilted forwards from the vertical by a maximum of 27 ° (with fixations at 9 °, 18 ° and 27 °).
The MFR was tested for the first time during the STS-41-B mission.
