As per reports, US Army has developed an exoskeleton which can be worn over the arm. The exoskeleton will help future soldiers to develop their marksmanship skills without the long duration of training typically involved.

The mechatronic arm exoskeleton is presently in its testing stage and will prove to be a potential future training tool. Maker of the exoskeleton said that its benefits would exceed the speed of skill acquisition.

The exoskeleton helps stabilize the solider's arm while aiming, with a series of sensors monitoring any slight tremor that can then be corrected, while still allowing full freedom of movement.

Some other benefits of these future tools include benefits like reducing the amount of ammunition used during training, thereby reducing training costs.

The exoskeleton arm, called MAXFAS, was recently detailed by Dan Baechle, a mechanical engineer with the US Army Research Laboratory.

Baechle said, "Soldiers need to be able to aim and shoot accurately and quickly in the chaos of the battlefield. Training with MAXFAS could improve Soldiers' accuracy, and reduce current time and ammunition requirements in basic training".

So far, tests conducted with MAXFAS have shown positive results. Findings of the test showed an improvement in the tremor many experience when, for example, holding out a laser pointer at arm's length and trying to keep it steady.

MAXFAS' tests showed that tremors were reduced and remained minimized even after the exoskeleton got removed.

The inspiration of making the exoskeleton came from a robotic device that is similar to it but used training stroke victims to regain arm motion.
