【超人战士或成真:美国陆军测试AI驱动的机器人套装】为保持军事地位,美军正在测试一种给予士兵有“超人能力”的外骨骼。外骨骼使用人工智能为士兵提供额外的力量和流动性,允许他们携带更重的负载;它附着在腿上,使用传感器来检测士兵的动作;测试过程中,它将执行任务所需的能量减少了9%。随着时间的推移,这个框架将会学习士兵正要做什么,并提供帮助。目前尚不清楚美军是否计划向所有士兵推出外骨骼。

Rise of the superhuman soldiers: US Army tests AI-powered robotic suits that make infantry 27 TIMES more productive

  • The frame uses AI to provide additional power and mobility to soldiers
  • It attaches to the legs, and uses sensors to detect the soldier's movements
  • Over time, the frame learns what the soldier is trying to do, and helps
  • During tests, the frame reduced the energy needed to perform a task by 9%

In the hopes of staying ahead of the enemy, the US army is testing a futuristic exoskeleton that gives soldiers superhuman abilities.

The exoskeleton uses artificial intelligence to provide additional power and mobility to soldiers, and allows them to carry heavier loads.

Early tests show that the exoskeleton has increased productivity anywhere from two to 27 times.

It is unclear when, or if, the US Army plans to roll out the exoskeletons to all soldiers.

THE EXOSKELETON

The frame fits around the soldier's legs, and is attached to a belt worn around the waist.

The belt connects to flexible hip sensors, which tell a computer where the soldier is in space, as well as the speed and direction of the movements.

It uses independent actuators, motors and lightweight structures, powered by a three pound rechargeable lithium ion battery.

During initial tests, engineers reported that Fortis reduced the amount of energy needed to perform a task by nine per cent, using AI to learn the gait of each soldier.

Mr Maxwell explained: 'It knows what you are trying to do when you are trying to do it.

'It locks and gives you a forward torque-twist that causes the lower leg to move toward the back, then it reverses direction to bring your leg forward.'

The exoskeleton, called Fortis, has been developed by experts at Lockheed Martin, and is being tested with soldiers at Fort A.P. Hill in Virginia.

The frame uses independent actuators, motors and lightweight structures, powered by a three pound rechargeable lithium ion battery.

This allows soldiers to carry 180 pounds (82 kg) up five flights of stairs, using minimal energy.

Keith Maxwell, senior programme manager of exoskeleton technology at Lockheed Martin, said: 'We've had this on some of the Army's elite forces, and they were able to run with high agility carrying full loads.'

Fortis could prove particularly useful in urban combat, because it enhances soldier mobility, power and speed, according to the engineers.

The frame fits round the soldier's legs, and is attached to a belt worn around the waist.

The belt connects to flexible hip sensors, which tell a computer where the soldier is in space, as well as the speed and direction of the movements.

The 'superhero suit' uses independent actuators, motors and lightweight structures, powered by a three pound rechargeable lithium ion battery. To put Fortis to the test, researchers recently tested soldiers' fatigue when walking and climbing stairs

PUTTING FORTIS TO THE TEST

To put Fortis to the test, researchers recently tested soldiers' fatigue when walking and climbing stairs, both with and without the exoskeleton.

In the study, four soldiers wore the exoskeleton and carried a 40 pound (18 kg) backpack, while walking at various speed on a treadmill inclined to 15 degrees.

Results showed that all four participants were less fatigued when wearing the exoskeleton.

Mr Maxwell explained: 'We were showing a decrease in the metabolic cost of transport, the measure of how much energy is required to climb uphill.'

During initial tests, engineers reported that Fortis reduced the amount of energy needed to perform a task by nine per cent, using AI to learn the gait of each soldier.

An earlier test by the US Navy found The Fortis exoskeleton increased productivity anywhere from two to 27 times, depending on the task.

The team measured the amount of time a worker could hold a 16-pound grinder overhead without having to rest his arms.

The longest operators could work continuously without a break was three minutes.

Using the Fortis, operators could work for longer the 30 minutes.

Mr Maxwell explained: 'It knows what you are trying to do when you are trying to do it.

'It locks and gives you a forward torque-twist that causes the lower leg to move toward the back, then it reverses direction to bring your leg forward.'

To put Fortis to the test, researchers from the University of Michigan recently tested soldiers' fatigue when walking and climbing stairs, both with and without the exoskeleton.

Mr Maxwell said: 'By reducing the effort in walking and climbing, there's less fatigue.

'This technology can literally help our fighting men and women go the extra mile while carrying mission-essential equipment.'
