European hedgehogs might be a popular garden visitor, but having to share space with humans can sometimes put them
That solution came in the form of a hedgehog “crash test dummy”. Developed by a team led by Dr Sophie Lund Rasmussen from the University of Oxford, the dummy is made from a soft rubbery plastic that’s designed to mimic the squishy body of a real hedgehog – and of course, its iconic spines.
To create a safety test using this dummy, it was first important to determine how
They found that the creatures either ran away, stood in front of the lawnmower slightly curled up, or started sniffing it. From this, the researchers could identify the best positions to put the hedgehog crash test dummy in to safety test a robotic mower, with the test itself then revealing if the device could avoid a hedgehog and if not, the level of damage it would cause to the animal.
“Cut injuries from robotic lawnmowers are placing an enormous burden on many hedgehog care centres and using up important resources, as these injuries often require above-average care and treatment,” said study co-author Dr Anne Berger in a
It’s hoped that the new safety test will lead to the development of more hedgehog-friendly robotic lawnmowers, something that Dr Rasmussen told IFLScience is already in the works.
”Our research has identified a potential threat to the hedgehogs, as some models of robotic lawn mowers – but not all – can be harmful to hedgehogs. Therefore, we have formed collaborations with industry partners to find solutions to this challenge by designing hedgehog-friendly robotic lawn mowers based on the knowledge gained through the research,” the researcher explained.
