DORA Robotic Arm

Students at the University of Massachusetts have developed a low-cost robotic arm that is capable of opening doors for wheelchair users. The special grippers on the robot arm that they have created can calculate the amount of force needed to open and unlatch the door. How well does this arm work? They have tested it on 14 different types of door handles with a success rate of 85 percent with pushing the door and 65 percent with pulling the door, which is amazing considering that this arm uses a single motor and no elaborate cameras or sensors. With a build cost of $2000, this is an impressive achievement compared to more expensive robotic arms that are currently available. Let us hope that these students can develop and refine this arm for consumer use.

Why Lithium Ion Batteries Are Not Used On Powerchairs... Yet

What do most laptops, cellphones, and some electric cars have in common? They all use lithium ion batteries. They are the latest and greatest in battery technology and can store twice as much energy for 33% less weight and last much longer than the conventional lead-acid batteries used in many powerchairs. So why aren't they used in chairs right now, you ask?

The big issues with lithium ion batteries are the testing, compatibility, and the costs. Testing these batteries for wheelchairs is ongoing since medical devices, such as wheelchairs, are subjected to much higher standards than in other applications. Reliability and safety (remember when millions of laptop batteries had to be recalled back a few years ago?) are crucial so testing to ensure that these batteries will not catch fire is important.

Compatibility is also an issue with most current wheelchair electronics since they have not been designed to handle the voltage and charging characteristics of lithium ion batteries. If lithium ion batteries are simply placed in most existing power wheelchairs, issues arise, from as simple as an inaccurate battery gauge reading, to as disconcerting as overheated connections. Therefore, power wheelchair electronics aren't yet designed to accept them predictably, and simply plugging in a set of lithium ion batteries into an existing power wheelchair proves problematic. Therefore, power wheelchair electronics need to be enhanced for compatibility with lithium-derived battery technology.

The final issue is cost. A set of lithium batteries that are similar in size to standard lead-acid batteries cost about $3500. When the lead-acid sets costs about $400, consumers and insurance companies are going to go for the cheaper option, despite the advantages that lithium ion can offer. Consumers struggle to fund basic mobility products – and often have to fight insurers for it – so $3,500 for batteries is simply out of consideration for most.

At least developing and refining battery technology is one of the biggest global technology trends, where environmental concerns are pushing towards better, safer, and cheaper batteries for all sorts of applications, including wheelchairs. In time, we will have new batteries in wheelchairs that will not only be safer and environmentally friendly, but allow us greater freedom and range to get us around. It is only a matter of time.

iPhone Users: Your Wheelchair App is Coming

Dynamic Controls is readying an iPhone/iPod Touch app that will cater to wheelchair users. Need to know how fast you are going? Need a compass to know the direction you are heading? Need to troubleshoot a diagnostic issue with your chair? This app has it. It will even tell you the battery level of the chair, if you need it. The developers are also working to have it connect to a chair's ECU so you can control your appliances or even check the IR or Wi-Fi status of the appliances you are controlling. Control of your wheelchair could even be possible through this app. Cool, huh?

This is set to be released for iPhone 3G, 3GS, and iPod Touch v2.0 and 3.0 by April 2010.

WheelchairForMe.com

WheelchairForMe.com is the only independent and completely free power wheelchair provider matching engine. Their goal is to match each visitor to the WheelchairForMe.com site with the best power wheelchair for their specific needs. The service is entirely free and thousands of satisfied customers can attest to the speed, diligence and knowledge of the WheelchairForMe.com mobility team. They only work with trusted providers to ensure that if the client qualifies he will receive a no or low cost power wheelchair delivered to their door!

Their service starts with the client. The focus is on providing the best experience for the client as they start the process of getting a mobility device. Most of the people who come to the Wheelchairforme.com site are individuals who have never had a wheelchair before and have only recently realized they need one either due to an injury, age or health issues. This can be a difficult time and WheelchairForMe want this process to be as smooth as possible for them. WheelchairForMe primary function is to match an individual who comes to WheelchairForMe.com to a trusted wheelchair provider that can match their unique needs. They have a database of trusted wheelchair provider partners who they have worked with and know are high quality companies with a strong customer service and performance record. WheelchairForMe looks at each visitor’s needs and match them with one of these partners who service their area.

During the process of matching the client with one of WheelchairForMe’s trusted partners, WheelchairForMe also strives to make them an informed consumer. They want to make sure visitors to the WheelchairForMe’s site understand their rights under federal, state or private insurance. They also want to make sure they understand they are not getting a “free” wheelchair. In the optimal case, one of the matched providers will get a client a power wheelchair that is completely paid for by their insurance. This means the client has no out of pocket expenses, but someone is still paying for the power wheelchair – the insurance company, or technically the taxpayers through a government program. WheelchairForMe’s goal is for all of their clients to get this optimal situation, but the truth of the matter is not everyone has the right insurance to achieve this. WheelchairForMe makes sure their clients understand this and understand that in some cases they may need to pay for a portion of their wheelchair.

On top of understanding the wheelchair acquisition process, WheelchairForMe has a number of resources on our site ranging from their user forum, their blog, articles on mobility topics, wheelchair reviews and a FAQ section that are all frequently updated and added to. Many of WheelchairForMe’s clients continue to come back and visit us for the information on their site long after they have received their wheelchair.

WheelchairForMe’s service and the information on their site is completely free. There is no charge from WheelchairForMe.com to visitors and individuals who use their matching technology to find the right wheelchair provider for them. WheelchairForMe continually works to improve their services and their information resources to better serve their clients. Check out their site here.

Latest Episode of Fox's Glee Focuses On Artie

This is the latest episode of Fox's newer shows, Glee. This is a show that tends to celebrate diversity and the underdog, such as in the case for this episode. Artie is one of the members of the Glee club who happens to be a wheelchair user. I do not wish to go into the details of the episode since I do not want to spoil it for anyone, but let me just say that it is worth it to watch and see what happens. Enjoy!
