Space transport and manipulation system (STMS) is a robotic system designed for extravehicular activity [4-7].
An application of this would be to provide predictions in cases where astronauts are exposed to disparate environmental conditions during extravehicular activity, since thermal comfort must be ensured even in thermally disparate environments.
A much smaller backpack unit was later designed and tested in 1994, but it was developed for emergency use, not routine extravehicular activity.
After ten years of research, Gary Harris has completed an informative and thorough book on the creation, evolution, and employment of the advanced extravehicular (EV) space suit--a suit "whose primary function is EVA (extravehicular activity), and is conceived with that goal as its primary driver." The suits used during past manned space-flights were based on an intravehicular (IV) configuration that limited their usefulness for long-term lunar missions.
What if you're out in an EVA (Extravehicular Activity) that is, you're out in your space suit, walking around, or perhaps even at some significant distance, on Mars, from the base, and a dust storm comes and you can't see anything.

Today's astronauts perform extravehicular activity (EVA), or spacewalks, up to seven hours at a time in virtually a "wearable spacecraft."
NASA uses Jack to simulate a person in surroundings as diverse as the shirt-sleeve environment within a spacecraft and the cramped conditions inside a space suit during extravehicular activity. Recently, Jack helped designers of the International Space Station determine where they should place the footholds for astronauts performing assembly tasks in the weightlessness of space.
in a space walk, but found his equipment so troublesome that he terminated his extravehicular activity early.
