Robotic Bees for Agricultural Purposes

INTRODUCTION

RESEARCH PROBLEM

1. Studies indicate that natural gas-methane leakage may be so widespread that it actually represents a lower greenhouse gas emitter per unit of energy than coal. This is because natural gas has a much greater harmful greenhouse effect than the carbon dioxide resulting from the combustion of carbon-based fuel. Developing a technology that makes it easy to find leaks helps them get repaired.

Methane leaks are a key factor in the country's gas boom as raw emissions can negate CO2 emissions from burning other fuels. The new report suggests that using more gas to mitigate climate change over 100 years has great benefits but cannot help in the short term.

This is because leaks and unplanned flags venting from storage tanks and processing plants are likely to be larger than previously realized. They seem large enough to make a carbon-to-gas shift effectively meaningless over a 20-year period, according to estimates from about two dozen scientists working with the Environmental Defense Fund, a nonprofit environmental group.

1. Populations of honeybees have fallen in recent years, and many researchers have blamed a class of widely used insecticides, called neonicotinoids. Without insect pollination, around 33% of the plants we eat should be pollinated by different means, or they would create fundamentally less sustenance. Up to 75% of the plants would lose some productivity.

The latest estimate of the worldwide economic benefits of pollination amounts to some 265 billion euros, measured as the value of natural pollination crops.

This, of course, is not a real value because it hides the fact that natural pollination, if severely impaired or terminated, could turn out to be impossible - making its true value infinitely high. And how much value can we attach to the abundance of color that greets us, for example, on a bright spring day? Most wild plants (around 90%) require animal-mediated pollination for engendering, and in this manner other ecosystem services and the wildlife habitats they give, depend specifically on insect anti-agents. Honey bees, alongside numerous wild species - are the overwhelming and economically most critical gathering of pollinators in most geographical areas.

THE PURPOSE

The objective is to tailor the framework to particular tasks, for example, observing plant growth and detecting gas spills. Scientists even trust that it might be possible to equip them with smoke locators so they can find forest fires speedier than greater robots.

Robotic bee could inspect crops, track forest fires, scavenge through rubble and look for survivors and identify gas spills, especially methane to warm the Earth's atmosphere, an intense ozone depleting substance that is ordinarily stronger than carbon dioxide.

The device could likewise have important agricultural uses, fly down into the plant sky, search for sicknesses and measure parameters, for example, moistness, with significantly better subtle elements than is conceivable with drones, taking into consideration another sort of smaller scale cultivating locally adjusting the earth to improve yields, these modest robots could act like honey bees and independently pollinate crops. The drones would carry pollen starting with one plant then onto the next, utilizing sensors and cameras to distinguish the areas of the yields.

HOW DOES IT WORK?

The goal of the researchers is to develop for such purposes once an artificial insect that flies completely autonomous. So far, however, Robotic bee is not yet: Eight outer cameras are watching the little robot in flight and send every movement to a computer that takes over the control. And Robotic bee has not really kept it in the air for a very long time: After just 15 minutes, the robot insect failed in the first flight. Material fatigue is still very high and there are also problems with energy supply. The mini bee is still powered by a thin cable. Leashed, she could not possibly fly a mission! A correspondingly small battery, with which the bee could take off, gives it so far not yet. In about two years, the researchers want to get the biggest problems of the mini-robot under control. Then, hopefully, Robotic bee can whiz through the air unleashed.

Since water is about 1000 times denser than air, other propulsion conditions apply: Air propellers are not efficient for moving in the water because their rotation speed must be significantly reduced.  Otherwise, the fine wings might break in the water. Therefore, the researchers let the mini-robot flutter in two frequencies - in the air around 260 hertz, in the water at about 11 hertz.

Four balancers with jibs on the ends make the unit about four inches long and keep it upright in water. But the core of the robot is a small rectangular box with a lid made of titanium and the plastic polyimide as well as side walls made of carbon fibers. The box literally has it all, because it contains an ignition device and electrodes that can be used to break down water into its constituent’s hydrogen and oxygen by electrolysis.
