Building an Artificial Intelligent Unmanned Unicycle

November 24th, 2012

Is it possible to build an unmanned artificial intelligence unicycle? We know it is hard for the human being without practice to ride a unicycle, because it takes balance and coordination. Building an artificial intelligent unmanned unicycle will not been easy chore and right now even the top robotics scientists and the top researchers have only yet built a motorcycle which can drive itself without falling over. And even that is problematic as it to falls over once in a while.

Now then I propose to build an artificially intelligent unmanned unicycle which has weights which move around to keep it upright at all times without the rider on it. How so you ask? Well I propose using the same system, which is in the Segway Scooter which keeps the scooter from falling forwards or backwards and dumping the standup rider.

Next I propose a motor on the stem above the wheel that is connected to this device, which stops and moves the wheel to keep it from falling backwards or forwards. Now then, I propose something that looks like a captain’s wheel on an old wooden ship be placed on the stem that leads to the seat where no rider will sit.

Additionally this wheel I propose to be made out of aluminum and hollow with weights inside. With the computer system attached to a level, which shows that the unicycle is falling in any direction other than forwards in backwards it will initiate a weight to move to the opposite side from which the unicycle is falling.

I am pretty certain we can build an artificial intelligent unmanned unicycle. Now you may ask why? And many people ask why people climb mountains and why they build kites and why human beings even exist. » Read more: Building an Artificial Intelligent Unmanned Unicycle

Global Wind Patterns

November 24th, 2012

Although winds can change on a daily basis, there are some consistencies in world wind patterns. Working from the equator to the poles, there are three bands of wind direction in each hemisphere. From the equator to about 30 degrees latitude (about a third of the way to the poles), the winds come from the east and are called the trade winds. Actually, they come from the northeast in the northern hemisphere and from the southeast in the southern hemisphere. In the middle latitudes, from 30 degrees to 60 degrees, they come from the west and are called the prevailing westerlies. And from the poles, they come from the east and are called the prevailing easterlies. The Coriolis force causes them to arrive at slight angles.

What regulates these winds are three distinctive cells or circular wind patterns in both the northern and southern hemispheres – one near the equator, one at the poles and one in between. The trade winds from both hemispheres converge on the surface at the equator, which sends the air aloft, reducing the pressure. This is why it rains so much around the equator. When the air reaches the upper altitudes, some of it heads north and some heads south in an effort to even out the heat difference between the equator and the poles.

At about 30 degrees latitude, the high-altitude winds sink to the surface. Sinking winds create high-pressure zones, with lots of sun, which is why 30 degrees latitude is where the world’s great deserts are. Some of that sinking air heads back to the equator, which keeps this cell or circular wind pattern going.

Some of the high winds descend at the poles. From there they head back toward the equator and converge with the prevailing westerlies at 60 degrees. When winds converge, they rise. This, you get another area of frequent storms at 60 degrees.

In general, there are a number of prevailing wind conditions on the surface and at higher altitudes in both hemispheres that greatly affect the weather. Where winds converge on the surface at the equator, the air moves upward and you will have lots of storms and rain. » Read more: Global Wind Patterns
