Science news: Robot cockroach crash dummy will climb walls after scientists research | Science | News


They are perhaps the most sturdy animal to ever grace the earth and are well known to be able to withstand a nuclear bomb.

But now they are inspiring researchers who are fascinated by their crash dummy-like qualities, according to a report in the Journal of the Royal Society Interface.

The insects don’t swerve when they see a wall coming, but ram into it and use the force of the collision to launch themselves upwards.

Inspired by this, Scientists have developed a sensorless, palm-size robot with a soft, roachlike exoskeleton and six legs which is called the Dynamic Autonomous Sprawled Hexapod.

Most robots tackle obstacles by sensing and then dodging around or climbing over them.

But this takes time to make such a decision, limits their ability to move around at high speeds and slows them down.

Although it can’t scale a wall yet, the robot can shift from horizontal to vertical movement by crashing into one – like a cockroach.

The robot is only 16 grams because as animals increase in size they hit obstacles with more energy during collisions – making them more susceptible to injury.

Researchers calculated that animals weighing less than one kilogram are able to use the cockroaches smashing ability.

The scientists believe the new work could lead to the development of less complex but more sturdy robots that can navigate complex environments at higher speeds.
