America’s Dynamic Controls unveiled its latest technology at world’s top trade fair for those with special needs and requiring care – REHACARE in Germany. Company integrated an iPhone into its power wheelchair electronics. Apple’s iPhone can now be considered accessiblity product, enabling powered wheelchair users to use them as normal while also gaining access to detailed information and control system access of their chair using the device. iPhone or iPod touch (iPhone 3G, 3GS, iPod touch V2.0 and 3.0) can be connected to the wheelchair system, and as result can display chair information in real time. This includes speed in kph or mph, compass heading and detailed wheel chair diagnostics (that interprets problems with the wheel chair).

iPhone can be fitted to any new or existing Dynamic Controls DX2, DX or Shark electric wheel chair.  A cradle is available to mount the iPhone or iPod touch onto the wheelchair, connecting it with control systems. This requires no reprogramming of the wheelchair, and can be done at home. While connected, iPhone is charged from the chair’s battery.

Upcoming versions of Dynamic Control’s software might even allow further control of the wheel chair thru iPhone interface – something similar as MIT showed with WiFi… First response from user base is positive, as the idea to be able to buy an off the shelf product that has so many features for powered wheelchair users is appealing.

Honda announced the personal mobility device, the U3-X. Device looks like robotic unicycle, and is designed to help people with disabilities to move around. Honda will showcase U3-X personal mobility device at Tokyo Motor show later in October.

U3-X is based on technology developed in Honda’s humanoid robot Asimo. Honda is well known for its R&D in robotics and assistive technology, and although its announcements are many (see the one about artificial robotic leg) most of this is still years away from production and sale. Looks like Honda is competing heavily against local rival Toyota, which is also aggressive on robotics and research – and both move in similar direction (toyota shows segway personal transporter with seat, toyota and mind controlled wheelchair, toyota i-swing personal mobility device)…

Anyhow, U3-X is on contrary with Toyota’s i-Swing a small device, which is also very portable. It can be carried around and put in trunk with ease. U3-X has a seat height a bit higher than an average person’s waist line, so passenger must “jump” on it to commence the ride. Passenger then puts his his feet to the foot rests (similar as found on motor bikes). The rest is already known from segway – passenger leans in the direction he wants to go, and U3-X personal mobility device moves. It can drive in 8 directions (cross and diagonally as well) and reaches a top speed of 3,7 MHP (5,5 km/h) – meaning that it moves at pace of average persons walk.

Honda’s chairman Takanobu Ito commented that “And if my legs get a little weak, I would like to have one of these around the house. It makes it easy to move about.”. We guess he has a big house… Honda did not want to comment on price and availability of the U3-X nor any plans to produce similar versions of power wheel chair or electric wheel chair devices like toyota i-swing where user sits and leans back on it…

Today experts from Veda International Robot Research and Development Centre in Japan, unvieled the prototype of a new type of electric wheelchair. New, high tech robotic wheelchair looks more like a scooter than traditional wheelchair, but it promises greater mobility for injured hospitalized patients, and hopes to replace not only existing wheelchairs but also two-wheeled vehicles of future.

New electric wheelchair is called Rodem. User sits on the four-wheeled wheelchair similar like on scooter. User rests his knees and chest on the cushions, steering the wheelchair with a joystick wile holding on to motorbike-style handles. The result is that user feels less load on their body.  

The whole new approach to electric wheelchair design allows users to mount the device more easily, and dismount it quickly and with less strain and pain as well. Target audience are elderly, hospitalized for smaller injuries which prevent them from freely moving around without help. Rodem is lessening reliance on care-givers to lift these patients.

Rodem promises greater mobility. Its prototype was demonstrated in the medical university in Tokyo. The two main wheels of the Rodem are independently driven by a control valve type lead battery. Autonomy of the electric wheelchair is around four hours per charge. Maximum moving speed is 6km/h, but can be set to lower limits as well. The dimensions of the Rodem are equivalent to the size of a normal wheelchair, and it weights about 200 lbs (100kg). It also features small minimum turning diameter.

Devices controlled with brain-waves are becoming a reality. On Monday, June 29th 2009, Toyota demonstrated an electric wheelchair, controlled by user’s brain waves. Approach is similar to other stories we covered in past (Live demo of mind-controlled electric wheelchair, Brain Controlled Electric Wheelchair and Mind Controlled Mouse Pointer (part 1), Brain Controlled Electric Wheelchair and Mind Computer Mouse Pointer (part 3 + The conclusion), Intelligent Autonomous Remote Controlled Electric Wheelchair).

User still needs to attach sensor grid on the head. The EEG sensor cap  measures electrical activity in the brain through five electroencephalography (EEG) electrodes. These are placed above the areas of the brain which handle motor movement. The sensors interpret the signals they pick up and translate them into motion.   System processes thought patterns without learning or training and translates them into movement of wheelchair. Electric wheelchair can accordingly move left, right or forward. Sensory system is processing data in real time, so delay between the thought and action of wheelchair is less than 125 ms. Competitive solutions require substantially more time – growing to seconds, which makes movement less natural and more difficult. Toyota’s solution (well, actually Toyota is only a sponsor of researchers from BSI-Toyota collaboration center) does not require the driver to learn special “signals”, but instead this mind-controlled electrical wheelchair will move forward when driver thinks of walking. According to Toyota the wheelchair is able to understand a record 95% of all commands coming from the drivers.

Toyota representatives described growing demand on similar accessibility products by Japan’s growing older population (in 40 years the percentage of seniors will account for more than 40% of Japanese population). Thinking is natural, and requires less learning so  brain-machine interface system will be more robust and simpler than voice-controlled system. System even “learns” by analyzing the behavior of the driver, which means that driver can improve the accuracy over time.

Japan has been always very strong in advanced robotics, and recent encourage by government fueled new research and development even further. It comes as no surprise, that other Japanese companies like Honda and Hitachi, are also working on brain-wave-machine technologies.

The Massachusettes Institute of Technology (MIT) has recently invented a self-navigating electric wheelchair. But this is no ordinary electric wheelchair that operates through GPS because is uses the latest Wi-Fi technology that can also be used indoors. To operate this device, it has a microphone and screen for visual and audio input options to make it easier to use. According to its one of its developers Nicolas Roy, the Wi-Fi operated wheelchair can learn and adapt to its user through voice recognition. Since it can be used indoors, it will be able to identify a certain building, as to where the user has to go even on the first “orientation.” 

For its initial test, there were 100 patients with multiple sclerosis and brain diseases at a Boston Home in Dorchester who tried out this system. Other considerations for improvement are still studied at MIT by other scientists involved in this project that uses Wi-Fi like side-field cameras and laser range finders setup with computers to create an internal map around the environment as the user moves around, even outdoors. Roy also thought about adding collision-avoidance system that uses detectors for the wheelchair to refrain from bumping into walls and other wheelchairs, as well as other obstacles.

This is a bit older news, but somehow it got unnoticed by us at the time of launch… But still it is so interesting, that we are fixing our mistake and running a story! French company named HMC2Development has launched a stair-walking motorized wheel chair named TOPCHAIR in mid 2007! The motorized wheel chair was in development since 2001. This was even before the well known and world-wide appraised iBot Electric electric wheelchair… But the iBOT is a wheelchair that runs on wheels, and was first developed in 90s. While it can actually rise up on the rear wheels to attain a stand position and also has a certain capabilities of climbing stairs, the fact that it runs on wheels, makes this type of wheelchair less stable and so it has its limitations compared to the Top chair stair climbing wheelchair.

Topchair uses different approach to conquering the stairs, as it uses rubber tracks similar to those found in tanks. This technology allows Topchair motorized wheel chair to go up or down the 20 cm high step (8 inch) made from metal or wood or concrete with maximum slope of 33° (65%). It does so while user sits comfortably and safely onboard without any help of  fixed structure like a ramp and with no need for an attendant.

Topchair uses two 60 Ah gel batteries, allowing it 35 km driving authonomy or over 300 steps in a single charge.

You are a big, strong person.  All your life you’ve been known as rugged, out of doors, and powerful.  Your first toy was a fire engine, your first pet was a husky, and when you got your first car, it was a truck.  You know all the back roads by heart and you’ve never let anything get in your way for long.  Now, life has put a new obstacle in your path; physical disability.  Are you the type of person that is going to let that slow you down?  Doesn’t sound like it to me!  If life says you need a wheelchair, then you should demand one that matches who you are.  A heavy duty person needs a heavy duty wheelchair.

The difference between a normal or electric chair and their heavy duty counterparts lies mainly in the construction.  A conventional wheelchair will work soundly for many years on pavement, asphalt and indoors.  They are meant for mainly urban and suburban environments.  But try and take a conventional model down a trail, or over other bumpy terrain, and more than likely it can break.

Owning a portable wheelchair is an important first step towards reclaiming the independence that a disability can take away from you.  Mobility is often times a challenge for the disabled, but it need not be.  Putting an emphasis on portability instead of overall ability can change one’s entire outlook on life.

Owning a portable wheelchair means several things, some of them bad, but many of them positive. Consider that most wheelchairs can be a two person undertaking.  This means that while in your chair, you will have a friend, family member or loved one always behind you, helping you on your way.  For many, this is very comforting.  Companionship of this sort will also help to bring you closer to those around you, and help elucidate the many reasons to be happy that these people are in your life.

Knowing the right wheelchair for your needs is crucial to finding happiness in your life.  Depending on your type of handicap and several other factors, you may find yourself looking for an electric wheelchair.  You should always consult with your doctor before making any decision of this magnitude, but rest assured that you have many viable options.  Making sure that you have the right electric wheelchairs scooters can make your life so much easier.

First, what is the difference between a scooter and a normal wheelchair?  The main difference is, more power!  While a normal wheelchair is propelled by your arm strength (or hopefully, the arm strength of a good friend or family member, walking behind you) a scooter is powered by a battery.  While in an electric scooter, the occupant simply pushes a joystick in the direction they want to go, and a silent, powerful motor drives the chair.  It is safe, efficient, and in some cases users report that the experience is downright fun.
