【可以自我平衡的“机器人套装”,让瘫痪者再次行走】法国一家创业公司已经开发出一种外骨骼装置,它可以帮助完全下肢瘫痪患者行走,不用拐杖或轮椅。这个装置称为“AtalANTE”,是一种机器人套装, 有两个可移动的腿和一个靠背,可以通过肩带连接到使用者。AtalANTE使用复杂的计算机技术和马达,可以分析人的步态或行走方式,保持平衡来模仿人类行走。目前AtalANTE正在接受患者试验,开发者希望在2018年底开始销售该设备。

Incredible self-balancing 'robotic suit' that uses algorithms to mimic how humans move could let wheelchair users walk again

  • A French startup built a 'robotic' exoskeleton that helps paraplegic patients walk
  • It attaches to the user's legs and back via straps that distribute pressure evenly
  • A series of motors in the hips, knees and ankles communicate with a computer, which analyzes the person's 'gait', or how they walk, in order to stay balanced
  • Developer 'Wandercraft' hopes to begin selling the device by the end of 2018 

A French startup has developed a futuristic exoskeleton device that can help patients with complete lower body paralysis to walk without crutches or a walker.

Called the 'Atalante', it's a robotic suit that uses sophisticated computers and motors to emulate the way humans walk.

The device was developed by Paris-based Wandercraft and is now undergoing patient trials, with the hope of going on sale soon.

Users begin by sitting in the device then moving their hips, which tells the motors in the hips, knees and ankle to move, forcing the device into a standing position.

Atalante has two movable legs and a back rest which are attached to the user via straps that help distribute pressure uniformly.

The user puts their feet on metal pads that have rubber grips.

The back rest features a battery and an Intel i7-equipped microcomputer that judges how the machine should balance and walk, according to Engadget.

Wearers can either use gestures to control the device, or a professional can direct it using special programs.

Atalante is the fourth generation of Wandercraft's lower body exoskeleton devices and weighs about 130lbs.

The device was developed by Paris-based Wandercraft and is now undergoing patient trials, with the hope of going on sale soon.

For now, the device moves relatively slow, but that's expected to get better in subsequent iterations.

The most important factor is that the device has to have perfect balance, so as to not injure the patient.

'We discovered that stability and human gait are some of the hardest problems we've ever encountered in robotics,' Managing Director Matthieu Masselin told Engadget.

Wandercraft has been developing the device for several years now and has sought to make sure it follows various medical protocols before it's ready to hit the shelves.

With design and development now complete, the firm is working to figure out how many patients and medical personnel need it, Engadget noted.

Currently, there's no demo videos showing the device in action, but Wandercraft prefers to show footage of the Atalante to medical organizations first before debuting it to the public.

HOW DO WANDERCRAFT'S EXOSKELETON  LEGS WORK?

A French startup has developed a futuristic exoskeleton device that can help patients with complete lower body paralysis to walk without crutches or a walker.

Called the 'Atalante', it's a robotic suit that uses sophisticated computers and motors to emulate the way humans walk.

It was developed by a French robotics firm called Wandercraft.

To use it, the wearer sits into the device and begins moving their hips.

In doing so, that activates motors that are located in the hips, knees and ankles, which forces the device to stand upright.

A computer located in the device's back rest helps analyze a person's 'gait,' or how they walk, in order to balance the device and propel them forward.

The back rest and legs are strapped to a wearer in various places to distribute pressure evenly and so that the device remains comfortable.

The firm hopes to have the device in medical facilities by the end of this year, as well as achieve FDA approval to sell it in the US, Engadget said.

In the near future, the firm may develop a lighter version of the device that enables patients to walk out of their house, but it will have to be able to ascend and descend stairs.

But the firm has made considerable progress on the current version of Atalante and has experienced success among paraplegic patients who have tried the device.

'There was such a strong emotional response from our test subjects,' Masselin explained.

'For a lot of them, it was the first time they had been able to walk since their accidents'

What's more, by developing a device that allows paraplegic patients to stand, it can help them avoid many of the common issues they deal with, like cardiovascular problems, pressure sores, eroding muscle strength and even depression, Engadget noted.

'Our friends in wheelchairs told us, '"OK, if there was a device that would enable us to be able to walk again, there is no price that I wouldn't pay,"' Masselin said.

Wandercraft isn't the only startup focusing on the exoskeleton space.

Japanese robotics firm Cyberdyne has developed a futuristic HAL Robot Suit that it hopes to bring to the US.

HAL operates using a mix of voluntary control and autonomous control via bio-electric signals. It's strapped to a patients' lower torso and legs and is able to pick up brain signals to walk

Cyberdyne noted that HAL isn't supposed to be a temporary exoskeleton, but rather a temporary pair of legs to help patients in rehabilitation.

Cyberdyne has been developing the Hybrid Assistive Limb (HAL) for nearly a decade, but only now has the firm been able to bring the technology stateside.

The robot suit fits around the wearer's midsection and legs to provide support for people who are otherwise unable to walk on their own, such as people who are suffering from a spinal cord injury.

Wearers control the suit using their brain, as the machine is able to pick up bio-electric signals, or an electric current given off by tissues, organs or cell systems.
