Spy Robots

Imagine a drone which can stick to the walls, fly, and proper itself out from the water and can also securely land when required. A drone which can easily fit in the palm of your hand – sounds amazing right? People have this fear that robots are now becoming similar to humans, however, they’re actually becoming more bug-like each and every day. A group of researchers from Harvard University proved that the robot flight is basically copying small bugs that were there on the ceilings and walls.

There’s a wide range of applications for similar robots, ranging from tiny spying devices which can be used to conduct surveillance missions, to scientists using them to go where no sensors can reach. Till the time when robots will be in the air, hovering can take as much energy as flying can. Additionally, a new study published that considerable energy can be saved if we plan on using tiny robots which can simply land and rest between jaunts. It’s similar to how a bee might land somewhere after taking off again.

When we use the word robot, we’re not talking about some terrifying robots from the movies or directly from the future. Instead, we’re talking about creations like RoboBee. This drone was made by Harvard John A Paulson School of Engineering and Applied Sciences. Due to the advancements in technology, this device can stabilise on the surface of water before an internal combustion engine will ignite to let it fly and bring it back in the air.

RoboBee was launched in Southern California in Los Angeles and weighs around 75 grams.

The major concern that was faced was the unknown weight of the actuators and how to make them flap. Scientists then came up with a new and improved design called ‘unimorph’ which depended on a single strip of piezoelectric material which would contract and expand while a current is passed through it.

This approach offered various advantages in terms of the dimensions, weight, control, aerodynamics and construction.

There is only one downside to the RoboBee – it’s basically not a drone because it depends on a tether as a source of energy. However, once the battery tech comes in line with the nano-scale robotics, the drone could work on its own perfectly.
