Inside the human body, the brain is the ultimate computer connected to the body parts to control these. Researchers and engineers work to design robotic frames that aim to help paralyzed people to walk again using the brain signals. MindWalker is the first exoskeleton prototype controlled by brain signals, a project started by the European Commission.
After three working years and new technologies developed, in the labs of several major universities and companies the first prototype took shape and was revealed. The external frame is connected to the human body, support the entire weight and move the legs in accordance with the brain signals.
Before the physical use of an exoskeleton, users have to learn how to use the brain signal system that control the exoskeleton. Developing a virtual-reality environment, users learns step by step how to control the mind-controlled exoskeleton virtually.
MindWalker can be divided into three main parts including the frame that support the body and animates the legs, brain signal reading system, and the simulation environment where the mind-controlled exoskeleton is represented by a virtual copy.
Researchers and engineers build MindWalker to be controlled in different ways, but only one control system is perhaps the best. Using an EEG cap to read the brain activity is perhaps the easiest way to control the exoskeleton for users. In addition, this control system uses a pair of glasses and flickering diodes located on each lens.
