This summer, two auto-driving wheelchairs appeared in Singapore Hospital and Japan Huda Airport.
The former was jointly created by Singapore-MIT Technology Research Union (Smart). Since September last year, the Supili General Hospital has emerged in Singapore, no nurse accompanying, it can carry a patient to go back and forth in the hospital hall. Smart has a lot of driving works in recent years. In addition to wheelchairs, it also developed automatic driving golf carts, electric taxi and scooters.
Daniela RUS, head of the SMART Future City Mobile Travel Group, said this automatic wheelchair R & D began in January last year. Now producing 4 test wheelchairs, two of which are in Singapore, and the other two are in MIT.
Don't take this wheelchair of Smart, it is equipped with 3 laser radar, and the data for airborne computers is a map drawn by laser radar. Subsequently, the positioning algorithm in the system will locate the position of the wheelchair in the map. In order to maintain a balance, this wheelchair has 6 wheels, which can not only go sharply, but also compact, it can easily pass the ordinary door frame.
"We have visited several older communities deeply experienced, and the quality of life of the old man can be easily close. We do this product is to let the people who are inconvenient to get the body's freedom." RUS Say.
The second automatic driving wheelchair recently appeared in the Tokyo Tada Airport, and its products were Panasonic and Whill, the latter has previously launched Model A high-tech intelligent electric wheelchair, and its battery life can reach 24 km. At the moment, the product has been sold in Japan and the United States.
Panasonic plans to deploy 5 MODEL M automatic wheelchair for technical testing this year. Similar to Smart automatic wheelchairs, Model M also used 2 laser radar. At the same time, it also uses the related art of Panasonic medical robot HOSPI.
"The path setting of the automatic driving wheelchair relies on existing map information and wheelchair location information." Panasonic spokesman Yamanaka said. Subsequently, the airborne computer will calculate the best path suitable for wheelchair walking. Users can select destination through smartphone applications, and they can even summon an automatic driving wheelchair like a Uber.
Model M can synchronize with the surrounding wheelchairs and is placed as a geese, which is very useful for collective passengers. After sending passengers, these wheelchairs can also be automatically ignited so that airport employees do not have to look around a wheelchair that is scattered in a corner. Yamanaka said that Panasonic plans to extend this wheelchair to large indoor facilities such as a shopping center.
According to Lei Feng.com, in addition to hospitals and airports, Smart is also conceiveing a network automatic driving travel system, users can sit in the wheelchair or scooter in the office, go straight to the golf car to the parking lot, then enter the automatic driving car Go home (people will not be lazy as pigs).
In addition, recent studies have found that both automatic scooters are still a wheelchair, it is quite good in walking environments.
Although automatic driving wheelchair is easy to use, I want to have a lot of commercial use, and the smart wheelchair sales in the market is relatively miserable. Expensive price is the main reason. For example, Dean Kamen's IBOT price is as high as $ 25,000, and it is no unattended. Therefore, RUS hopes that the next generation of smart wheelchairs can have a significant increase in cost performance.
"We are ready to develop a set of enhanced kits that can be used directly in traditional wheelchairs. Of course, the price of this automatic driving kit is enough." RUS said.
Of course, there is also a trick in the United States to promote automatic driving wheelchairs, that is, let their own products get FDA medical equipment certification, so that patients can get medical insurance reimburse, they don't have so much worries.
