Six-Legged Robots Run Speedier

In the most recent breakthrough to make the insect-inspired drones run speedier, a team of Swiss researchers, led by an Indian-origin researcher, has found a new path-breaking method which can enable the sex-legged robots to boost up the speed of their walk. By following the patterns of how the insects enhance their walking speed, the Swiss researchers successfully managed to discover a potential method which may help them to increase the running speed of the insect-inspired sex-legged robots.

The invention came up a remarkable breakthrough of the researchers at University of Lausanne and École Polytechnique Federale de Lausanne in Switzerland. As highlighted by the scientists, the Six-legged creatures use their three legs to run at a faster speed. The process is called “tripod” gait, where the insects keep three of six legs on the earth always, keeping two on one part of their body and one on another body part. This enables them to run at a faster speed than other insects.

But in the findings, published in Nature Communications over this weekend, scientists mentioned about a more rapid way which can boost up the running speed of the six-legged robots. By locomoting two legs, instead of the robots on flat ground, the robots can achieve a higher rate. As they don’t have the adhesive pads which the insects use to clamber walls and ceilings, the researchers have provided the robots the locomote for enhancing their running speed.

According to Pavan Ramdya, co-lead and corresponding author of the study, “We seceded with the trivet-gait concept and mull over the idea of “bipod” gait as another prospect of locomotor strategy. By creating simulations in the robots, we were trying to come across new strategies which can enable the robots to run faster, like six-legged insects do.”

The researchers test multiple combinations of legs and try to recognise new tactics that might help the robots to walk and run faster and more efficiently to move all through the world. During the simulation process, they identified a new set of running and walking methods called ‘bipod gaits’. In bipod gaits method, animals can put two legs like the front left and rear right or the middle legs on the ground simultaneously and can run more rapidly across the world. This method is expected to optimise the expenses or the energy consumption capacity of the robot as it will enable it to move speedily, using only two of its six legs.
