It may be recalled that Electroencephalography tests are widely used in detecting epilepsy and Parkinson's disease. As a low-cost noninvasive method of brain monitoring, the EEG involves collection and display of data using wires, devices, electrodes, software and amplifiers.

In the present case, a high-tech EEG cap was pressed into service, which at the scalp is wired by 64 electrodes to convert the subjects' "thoughts" into action.

The trial was successful in almost eight subjects and their success rates in various tasks were recorded.

Wearing the cap, subjects are persuaded to move their hands without really moving them with an aim to control the robotic arm in a three-dimensional (3D) space.

They also had to visualize a virtual cursor on a computer screen for handling the robotic arm and grabbing objects that are stationary over a table.

Gradually, the subjects start moving the robotic arm and start grabbing objects from random locations including the lifting of things from a table just by thinking of those movements. All these movements had a high success rate close to 80 percent.
