TOKYO —Imagine a bicycle seat connected by mechanical frames(机械支架) to a pair of shoes for an idea of how the new wearable assisted-walking machine from Honda works.

The experimental machine, showed on Friday, is designed to support bodyweight, reduce stress on the knees and help people organize steps and stay in crouching(蹲坐) positions.Honda showed a video of its employees wearing the machine.

Engineer Jun Ashihara also said the machine is useful for people standing in long lines and to people who run around to make deliveries.

"This should be as easy to use as a bicycle," Ashihara said."It reduces stress, and you should feel less tired."

To wear it, you put the seat between your legs, put on the shoes and push the “on” button.Then just start walking around.

In a test run for media, this reporter found it does take some time to get used to the machine.  “I could sense how it supported my moves, pushing up on my bottom when I crouched and pushing at my soles(脚底) to help lift my legs when I walked,” he said.

The system has a computer, a motor, gears(齿轮), batteries and sensors in it, so it responds to a person's movements, according to Honda Motor Co.

Pricing and commercial product plans are still undecided.Japan's No.2 automaker will begin testing a prototype(模型) later this month.

The need for such mechanical help is expected to grow in Japan, which has one of the most rapidly aging societies in the world.

Other companies are also eyeing the potentially attractive market of helping the weak and the old get around.Japan is among the world's leading nations in robotics technology, not only for industrial use but also for entertainment and companionship.
