Mind-controlled exoskeleton to allow paralysed person to walk at World Cup

The Walk Again project aims to use technology to help overcome paralysis. It involves an exoskeleton system consisting of a cap with electrodes, a computer, a battery, and sensing legs. The electrodes pick up brain signals and transfer them to the computer, which converts them into movement. Sensors detect when the foot touches the ground and send signals to an electronic vibrator in the arm, helping patients associate the sensation with walking. Eight people are training to demonstrate this technology at the World Cup opener between Brazil and Croatia on June 12th.

What is the primary goal of the Walk Again project?

• To use technology to help people with paralysis

• To create a faster mode of transportation

• To develop a new type of sports equipment

• To design a new type of footwear

Which component of the system is responsible for picking up brain signals?

• The computer

• The sensing legs

• The cap with electrodes

• The battery

What role does the computer play in the system?

• It vibrates the arm

• It detects when the foot touches the ground

• It converts brain signals into movement

• It powers the electrodes

How does the system help patients associate the sensation with walking?

• By vibrating the arm

• By using a visual display

• By playing a sound

• By moving the legs

When is the technology demonstration scheduled to take place?

• During the Olympics

• At the World Cup opener

• At a technology conference

• During a medical symposium
