A Walking Robot Which Can Navigate Without A GPS

Scientists assert to have designed and constructed the first-walking robot that can explore the surrounding and find its way back home without taking the help of the GPS or any maps.
Researchers from the French National Center for Scientific Research (CNRS) have named this six-legged creation the AntBot. The researchers for developing this robot took inspiration from desert ants, who are amazing pilots. This new invention opened new avenues for the wayfinding of autonomous vehicle.
An insect of arachnid-based robots isn’t a new thing completely. Legged robots, as inimical to those on wheels are better to pass through in rough terrains. The skills were very well presented in a study that was published in Science Robotics on 13th February. The study pointed out that at some point of time robots would be able to find their way back home without a GPS.
The lead author of the study Julien Dupeyroux, an engineer and also a PhD student in Biorobotics at Aix-Marseille, stated that desert ants can ride great distances in search of food; however, they are not able to use their sense of smell to return back home, due to the blistering environments in which they live. However, they’ve found ways to make up for it. Julien even stated that during the whole period of the desert ants evolution, desert ants like
Cataglyphis have grown sensory approach in order to make them able to confine concerning their nest entrance.
In other words, the desert ants like Cataglyphis make use of various tricks to aid them in figuring out and recall their homes in the context of their present location, ability scientists call path integration.
For instance, ants’ compound eyes, contain unique photoreceptors that catch ultraviolet light from the Sun that’s become antithetical by scattered air molecules. The UV light, however, changes as the sun moves across the sky. By tracing these changing patterns, the ants can easily determine which direction they’re facing.
Dupeyroux along with his team used many tricks of the desert ants, along with the ants’ orance, to develop the 3D-printed, Raspberry Pi-led, fully autonomous AntBot. Then they sent the bot out to casually walking around for a short while in an array of environments, before being asked to return back home.
