The 'iron' dress serves the mission of Mars

The NASA is working on a robotic suit similar to the Iron Man movie, designed to help astronauts retain their muscles in the mission of Mars.

Robot armor weighing more than 90kg, called X1, can be used to support or control the movement of joints, according to NBC News.

The restraint system is designed specifically for astronauts who practice on-board spacecraft to Mars, or for long-term missions on the International Space Station.

The X1 is the version originated from NASA's Robonaut 2 project

In the opposite state, the robot robes will work with the wearer, allowing them to move efficiently and stably. This is perfectly suited for those who are unable to move.

Other potential applications of X1 include restorative physiotherapy, gait adjustment, and weight bearing. This is not the first robotic suit designed.

In August 2012, a woman who was paralyzed from the chest down after falling from a horseback was able to walk thanks to the Arman Medical Technologies' ReWalk.

And military contractor Raytheon is also researching Exoskeleton outfits for the military, aiming to equip "superhuman" capabilities for soldiers.

However, NASA claims the X1 is easy to wear, not bothering the wearer, according to a report by the Florida Institute of Human and Machine Sciences.
