Introduction

As you know that God is the creator of this sublime world of the living. Here, every organism has mastered its way of living, even a small cockroach who is one of those strongest bodybuilders in disguise that can even bear the weight of your squash.

This caught the minds of the engineers who now, have developed a small, scurrying bot based on this humble cockroach – with almost as much speed and squashability as its biological equivalent.

Being only a tenth of a gram, this marvellous creation can withstand the weight of a human which is almost equivalent to 60 kilograms or 132 pounds.

Detailed Insights

It's made from a thin sheet of polyvinylidene difluoride (PVDF), a piezoelectric material that expands and contracts with the application of a small alternating current.


That expansion and contraction gives the roach-bot its way of moving: by adding a front leg and an elastic polymer layer, the scientists got the sheet to bend in a way that propels it forward.

The team experimented with several lengths of robot (from 10 to 30 mm) and varied the frequency and voltage of the electric current to alter the running speed of their designs. At its fastest, a 10 mm robot managed to scuttle along at a whopping 20 centimetres per second when 200 V were applied at 850 Hz.

Right now the bot needs to be tethered to its electricity source, but a future version could be powered by a tiny battery.
