Google is still working on their self-driving car project, aiming to make driving safer, more enjoyable and more efficient. The Google Car has gone almost a million miles already on a test-drive, and no accidents have occurred. It even drove a blind man back and forth to a restaurant once!
How it Works
As you may know from the
picture, on top of the Google Car is a laser range finder mounted on the roof
of the car. It's actually Velodyne 64-beam laser, generates a
detailed 3D map of the environment. The car will actually combine
measurements with actual maps. There are four radars, that
allow the car to see traffic, a sensor that senses traffic lights, and a GPS
+ wheel encoder, which can tell where the car is.
Program Setback
Still, the car has some setbacks. It needs to be programmed to become more "aggressive." Such as, in an intersection, it yields to other vehicles; but if other cars don't reciprocate, it advances a bit to show to the other drivers. If they didn't program that type of behavior, it wouldn't be able to drive for people.
Pros:
-Google boasts it's driverless car could save millions of lives every year
-The car has a already driven more than one million miles with no accidents
-The car yields to pedestrians, even a person who decides to cross the street at last minute!
-This will eliminate drunk driving-caused accidents.
-The google car could double the capacity of roads by allowing cars to drive more safely while closer together.
-The google car could double the capacity of roads by allowing cars to drive more safely while closer together.
-They are very lightweight.
-They would decrease the amount of fuel
consumption
-They could even be ran on hydrogen and electricity
which would definitely help air pollution and fuel consumption
-Robotic cars will eliminate about 94% of all car accidents!
Cons:
-It needs to be programmed to become more "aggressive." (see Setbacks)
-You can never fully rely on robots, so accidents may still occur
-Currently, these robotic cars are very expensive to make. It reach up to two million dollars!

3D Printer
A 3D printer is an addictive technology where a 3D object is created by laying down many layers to create the three-dimensional look. The first 3D printer invented was based on a technique called stereolithography and was invented by Charles Hull in 1984. Stereolithographic printers is one of the most accurate types of hardware for assembling 3D output, with a minimum build layer thickness of only 0.06mm. How a 3D printer works:
There are several types of 3D printers and some work differently from others. However, all 3D printers "print" the 3D objects by transferring the substance in many layers onto a layered surface, starting from the bottom layer. Before printing though, a person must create a 3D image of the object they want to print on a CAD (computer assisted design) program. The 3D image is then cut into myriads of horizontal layers. These layers are then stacked on top of each other until the completed object is done.
Now lets say that you want to print a 3D image of a figurine. To do so, you do something called selective layer sinistering. It involves heating and solidifying granite-like material with a laser in a certain pattern for each slice before repeating with all the new layers. This is the technique to make a 3D image of a figurine!
Most printers can only print certain objects with specific materials. It is a limitation that prevents the 3D printer from printing complex items such as some Apple products and smartphones.
The 3D printer is giving a huge boom to the world, positively and negatively. In a positive way, we can share online blueprints and print it at home. That way, do-it-yourself makers can have another something to do. However, the 3D printer also has its negative side. Security experts are worried about the 3D printer’s ability to share digital privacy and sharing knowledge that could be dangerous if shared to the wrong person. A group in Texas has already started working on the first ever 3D-printable gun.
Overall, the 3D printer is a very fascinating technology!
Robotic Chicken Butcher:
Robotic Chicken Butcher... When you here that, you probably go like "What?!" but it's true! The Robotic Chicken Butcher is how boneless chicken parts are made, just recently. You see, a job in poultry plants is quite dirty and dangerous. They have to separate the shoulder joint from the body, and it requires a knife for hours i n a room at the temperature of a refrigerator. Well, this new robot will solve that problem.
This was invented from a team in the Georgia Tech Research Institute in Atlanta. The robot consists of a..
First of all, Gutted whole chickens sit on metal cones as they travel along a conveyor belt, just as they would in a conventional poultry factory.

Calculating
There are 2 robotic arms working, one arm for each side of the bird. By calculating the dimensions of one body the machines can deduce dimensions of other body parts.

Slicing
To remove the wings from the breast meat, the robotic arms slice into the chicken with a knife at the collarbone, move toward the shoulder, cut through the shoulder joint, and continue down the bird’s backside along the shoulder blade, all in two seconds.

This process is repeated almost nine billion times a year.
Pros:
-Prevent danger in these jobs
-Is easier, more effective
-The robot does it, therefore people do not have to be in cold temperatures receiving minimum wage
-It may be more sanitary this way, and the wings are cut more perfectly.
Cons:
-Since robots do it, people may lose their jobs.

When the SpaceX launches its Falcon Heavy rocket into space late this year, the craft will become the most powerful rocket in the world. Only NASA’s Saturn V, which sent Americans to the moon, has ever generated more power. In rockets, the most important measure of power is thrust. Falcon Heavy’s 27 individual booster engines together generate 3.8 million pounds of thrust. It is enough to allow the 3.1-million-pound rocket and its 117,000-pound payload to lift up and orbit the Earth. The Air Force has already hired SpaceX and its Falcon Heavy to send two satellites into orbit sometime in 2015.
1) THREE ROCKET CORES
Falcon Heavy’s first stage consists of three cores. All three cores operate together at liftoff.

3) CENTER CORE
For payloads heavier than 100,000 pounds, Falcon Heavy uses a cross-feed system to run fuel from the side cores to the center core, leaving the center core almost fully fueled after the side boosters separate. What’s left is the equivalent of a complete Falcon 9 rocket already high in space.

4) FUEL TANKS
A liquid-oxygen tank at the top of each core feeds the engines through a center tube.

5) SECOND STAGE
Powered by a single Merlin 1D engine modified to operate in space, the second stage delivers the final push that gets the payload into orbit. The engine can shut down as needed, enabling Falcon Heavy to deliver multiple payloads to different orbits.

6) FAIRING
Falcon Heavy can carry either a Dragon capsule—SpaceX’s free-flying spacecraft, currently used to resupply the International Space Station—or up to 117,000 pounds of payload enclosed in a shell 45 feet long and 17 feet in diameter. The fairing consists of two clamshell-style halves made of an aluminum honeycomb core and carbon-fiber face sheets.
Pros
- cheaper launch cost
-Powerful and faster than most of the other rockets
- Tested and is very safe
Cons
-too many materials
-can cause some atmospheric damage
