Although wheelchairs have proved their worth over the years in providing people with disabilities an increased level of mobility, the truth of the matter is that, in many cases, they create all sorts of prejudice, at least at a subconscious level, while not being able to get people closer to leading a normal life.

However, the researchers and engineers over at Rex Bionics might actually have a solution to this problem in the form of the Robotic Exoskeleton, which is most easily described as a pair of robotic legs that supports and assists a person who usually uses a wheelchair, enabling the person to stand, walk and go up and down steps and slopes.

Rex users self-transfer from their wheelchair into Rex, strap themselves in and control their movements using a joystick and control pad. REX is powered by a lightweight, long life rechargeable battery, which should last for a whole day without any problems.

Rex is the brainchild of two childhood friends, Richard Little and Robert Irving – co-founders of Rex Bionics. "Both of our mothers are in wheelchairs so we are aware of some of the obstacles and access issues faced by many wheelchair users," says Richard.

Each Rex is built onsite at the Rex Bionics' Auckland plant. Potential customers must complete a medical appraisal including checks with their own physician to ensure their general health and suitability before they can begin the process of fitting and training. This process typically takes around two weeks with Rex Bionics' team of technicians, based at the Rex Centre in Auckland.

Unfortunately, this very useful device will be also extremely expensive, since the Rex is expected to cost about US$150,000. However, given the advantages it provides, there are plenty of people out there who will be more than willing to pay this sum in order to even partially regain their level of mobility.
