Bionic arm for Hercules strength developed

Researchers have developed a revolutionary new bionic arm that can be just strapped on an external bicep to provide 'Hercules' strength.
The device, called the Titan Arm, developed by engineering students at the University of Pennsylvania, who created an upper-body exoskeleton that can be used in physical therapy and manual labour.
The Titan Arm straps directly to a user's right arm to help lift heavy objects that the user would not normally be able to lift, CNN reported.
The bionic arm attaches to a user's right arm with a power motor at its elbow joint.
The arm is predominantly made of aluminium and steel components, and is powered by a DC battery.

The bionic limb can lift more than 18 kilogrammes of weight, augmenting a user's natural strength.
The arm can be locked into any position with a ratchet brake to hold an object steady without any exertion from the user in addition to helping lift weight, the report said.
Researchers believe the bionic arm will be useful in aiding physical rehabilitation, both for people who have suffered upper body injuries and for those with pre-existing muscular-skeletal disorders.
