A robotic arm is a type of mechanical arm, usually programmable, with similar functions to a human arm; the arm may be the sum total of the mechanism or may be part of a more complex robot. The links of such a manipulator are connected by joints allowing either rotational motion (such as in an articulated robot) or translational (linear) displacement. The links of the manipulator can be considered to form a kinematic chain. The terminus of the kinematic chain of the manipulator is called the end effector and it is analogous to the human hand.
Doctors in Pittsburg are stunned by the ability of a patient who reached a never seen before mental control level of a robotic arm. The human part Jan Scheuermann, 53, who is paralyzed neck down, was able to move, grasp and release a variety of common household items with the same ability as with a [...]
Nothing short of extraordinary, two people paralyzed from the neck down controlled a robotic arm to perform actions of various complexity, like manipulating objects, simply by using their minds. One of the participants involved in the demonstration of the brain to robotic arm set-up actually controlled the arm to retrieve a coffee recipient and eventually drank from [...]
