With the advent of those 'bio-punk' renditions in our modern day life, this advanced albeit convenient conception comes as a welcome sight to bridge the gap between reality and fiction. Equipois, a company that makes tool support technology, has uniquely contrived of this exclusive mechanical arm that efficiently helps users like dentists, surgeons or even jewelers to keep their arm steady while working, as well as provide them with immense strength.

Supposedly inspired by Steadicam, a stabilizing mount for motion picture cameras, this innovative piece of technology is named as the X-Ar. Basically designed as a mechanically driven support to the arm, it comprehensively nullifies the biological arm's exhaustion and over-tiredness during long work hours. So the device can become immensely conducive in case of heavy yet delicate jobs like construction and even surgery.
There is also a conscientious side to it, as the the X-Ar could be used to assist paralyzed people in moving their arms by connecting with a brain control interface. Equipos CEO Eric Golden says:
We have met with some parts of the armed forces about helping brain-injured veterans. We're a little bit away from kicking that off.
The price tags range between $2000 to $3000 and it is expected to hit the markets in May; and it would certainly be a worthwhile wait for this contributive contraption.
