Scientists have trained a spider to jump on demand in a bid to unlock the secrets behind how the arachnids hunt.
The female spider, nicknamed Kim, was taught to leap different heights and distances by researchers who placed her a short hop from her nest and waited until she jumped home.
By recording her acrobatics with high-speed cameras researchers learned that the species uses different jumping strategies depending on the challenge ahead.
The team hope to use their findings to create a new class of micro-robots that jump like agile spiders.
As well as military applications, these robots could be used to catch insect pests or even clean your home, researchers said.
Dr Bill Crowther, a robotics researcher at the University of Manchester and co-author of the study, told MailOnline: Were used to robots bulding cars now but further down the road theres a whole other world of applications.
We have thought about natural pest control - instead of spraying chemicals to get rid of pests like greenflies we could have small robots do it instead.
They could also be used as part of cleaning technologies of the future.

The Manchester researchers said their work could help scientists understand why jumping spider anatomy and behaviour evolved the way it did.
Dr Mostafa Nabawy, lead author of the study, said: The focus of the present work is on the extraordinary jumping capability of these spiders.
HOW DID SCIENTISTS TRAIN A SPIDER TO JUMP?
Researchers at the University of Manchester trained a jumping spider nicknamed Kim to leap across different gaps.
Kim belongs to a species of jumping arachnid known as Phidippus regius, or Regal Jumping Spider.
Scientists filmed Kim with high-speed cameras in a bid to better understand how the species changes its technique to tackle different challenges.
Scientists bought four regal jumping spiders for the study - but Kim was the only one who could be bothered to jump, study coauthor Bill Crowther told MailOnline.
He said the team did not bait Kim across each jump with food.
Instead, they transported the spider between take-off and landing platforms several times, allowing her to become familiar with each gap.
They then tempted her across the jumps by placing gaps of varying difficulty between her and her nest.
Dr Crowther told MailOnline: Kim had a nest where lived throughout the day that had plenty of moss and water.
A jumping spider can leap up to six times its body length from a standing start. The best a human can achieve is about 1.5 body lengths.
Dr Nabawy said micro-robots modelled after jumping spiders could be used for a variety of different purposes in complex engineering and manufacturing.
He added the robot arachnids could be deployed in unknown environments to execute different missions.
Scientists bought four of the spiders from a pet shop in Manchester for the research - but Kim was the only one who showed any inclination to jump as required, researchers said.
She was trained to leap on demand from different heights and distances while her leaps were recorded with high-speed cameras.
Researchers said they did not use bait or prey to tempt Kim to scale the jumps, but instead transported the spider between take-off and landing platforms several times, allowing her to become familiar with each jump.
They then tempted her across each gap by placing her near her nest.
We put her on a different platform and, eventually, she would choose to jump home.
The team recorded her taking on jumps using ultra-high-speed cameras, and used high resolution CT scans to create a 3D model of the spiders legs and body.
The results showed the Regal Jumping Spider switches up its strategy to master smaller and larger jumps.
For example, to jump shorter, close-range distances Kim favoured a faster, lower trajectory which uses up more energy, but minimises flight time.
This made the jump more accurate and more effective for capturing its prey.
If Kim was jumping a longer distance or to an elevated platform, perhaps to traverse rough terrain, she jumped in the most efficient way to keep energy use low.
Insects and spiders jump in a number of different ways, either using a spring like mechanism, direct muscle forces or using internal fluid pressure.
What isnt known is if this hydraulic pressure is actively used to enhance or replace muscle force when the spiders jump.
Dr Crowther said: Our results suggest that whilst Kim can move her legs hydraulically, she does not need the additional power from hydraulics to achieve her extraordinary jumping performance.
