Narrator: Artificial intelligence

Is an area of computer science

Focused on creating Intelligent machines

That work and react to humans.

The term "Robot" First appeared in 1920.

It comes from The czech word "Robota,"

Meaning "Forced labor."

This facility makes A type of educational robot

Equipped with a series Of interconnected servomotors.

This type of equipment Allows the robot

To move with an extraordinary Degree of dexterity.

Construction starts From scratch.

Tiny bushings are created From a steel rod

Placed inside this high-tech Automated machining device.

A technician monitors The operation

As the machine shapes the parts With digitized precision

To the design specifications.

The high-speed steel bits

Carve the metal At an incredible speed.

This machine can Manufacture 1,309 parts

Per every eight-hour shift.

The parts fall into A vibrating mechanism

That feeds them into The next phase of production.

A specialized device Called a gear-hobbing machine

Quickly and accurately cuts A series of cogs

To create tiny sprocket wheels.

A technician uses State-of-the-art Measuring devices

To gauge the profile, Tooth alignment, and pitch

Of sample parts

To ensure they are up to Standards specified

In the manufacturer's Control plan.

Another operator mounts A gear plate on a device,

Fastening it to a smaller part Called the sun gear.

Once all the required parts Are tested and prepped,

Technicians begin Putting them all together

To create d.C. Motors.

Since the robots Are specialty items

With small Production quantities,

This facility is able to Assemble each motor by hand.

The gears used in the motors Are made of a variety of metals

To account for Different requirements

Of torque and loading force Within the device.

Moving with speed and precision,

Specialists are able To assemble each motor

In less than 10 minutes.

Next, the tiny control unit Is installed.

That will allow the user To manipulate the robot.

The technician Carefully attaches

The bottom portion of the unit Inside the motor container

With a small cordless drill.

Once the unit is firmly secured,

He expertly positions The wire leads

To prepare them For the next step.

A technician quickly Solders the wires in place.

Now that the installation of The control panel is complete,

A technician finalizes The d.C. Motor assembly

By attaching the cover

And securing it down With four screws

Using a cordless drill.

Next, the individual motors

Are installed into The framework of the robot.

One motor becomes The robot's head,

While the remaining motors Are attached to hinged joints

That correspond To a major body part.

Then the robot's wiring Is plugged in,

Ensuring the motors Are connected to each other.

They now form parts Of an integrated device

Which can act together.

Technicians use a 3-d printer

To create a suit of armor For the robot,

Which they mount on its exterior To give it a more finished look.

A specialist plugs the robots Into a computer

And programs Their different movements.

The robot tech communicates With the robot's control panel

To make it do remarkable things.

But first, an old-fashioned Rock 'em sock 'em

Before they take over the world.

Narrator: when professional Boxers win a title,

They're crowned the champ

And rewarded with a belt To be worn around the waist.

Each international organization Commissions a belt

That's custom-designed To its specifications

And prominently features The organization's logo

In the belt's central medallion.

These boxing championship belts Are entirely handcrafted.

The laterals, the side pieces Flanking the ornate centerplate,

Are sometimes engraved With a fighter's portrait.

When a boxing association Commissions a new design,

The company's artisans prepare A sketch for each piece.

Following the sketch, They sculpt a clay model.

From that, They cast a plaster model,

Then a metal model,

Refining the sculpture At each step.

Artisans use The final metal model

To produce a rubber mold,

Which is used to cast the piece In white metal.

The extracted castings Are quite rough,

So the workshop's craftsmen

Use files, chisels, And automated tools

To refine the shape.

Some of the devices And techniques

Are routinely used by jewelers,

While others were designed Specifically for this purpose.

Once the intricate details Are completed,

The team files down rough spots Along the perimeter.

The belts feature

A three-dimensional sculpture Of an eagle

Fused to the centerplate.

An artisan heats the wings With an open flame

To make them pliable.

Then he bends them to render The eagle more lifelike.

Every piece must be Meticulously hand-polished

On a buffing wheel.

This prepares the metal to be Plated with gold or rhodium.

The piece is electroplated With copper,

Then nickel, then 18-karat gold.

The nickel carries the shine Through to the surface.

After a thorough buffing On the surface,

The pieces are embellished with Crystals into molded cavities.

Sometimes The championship winner

May order precious stones Such as diamonds and rubies

To replace the crystals, Depending on their preference.

A team of enamelers Paints the finished pieces

With jewelry-grade enamel.

This requires a steady hand And close attention to detail.

Once the piece is painted,

It's put into an oven To bake the enamel.

The belt strap is made Of high-grade bonded leather.

A craftsman traces A belt template in the leather,

Then cuts it out with a knife.

Then they adhere the strap To leather or high-grade vinyl.

The designer sews The strap's lining separately,

Stitching black spandex Over a faux-fur backing

And attaching The authenticity label

Which bears The belt's serial number.

This distinguishes it From cheaply made copies.

The craftsman attaches Leather/high-grade vinyl piping

To the strap perimeter.

He places a brand sticker On the back

Next to an inscribed tribute

To the originator Of the modern boxing belt.

They adhere the lining.

Then, after smoothing out The layers of the belt

With a hammer,

The designer stitches The lining to the strap.

Some belts have buckles, Others hook-and-loop fasteners,

Which are stitched to the strap At the same time as the lining.

Once the belt is finished,

The centerplate and laterals Are attached.

It's essential to wear gloves While doing this

To protect the pristine surface.

The final step is to place An engravable brass plate

Into each lateral.

Then the championship belt Is delivered

In a hand-crafted Protective case

For a knockout presentation.

Narrator: Radar helps sailors navigate

Through inclement weather While on the water,

Ensuring they aren't Operating blind.

These specialized Pedestal mounts

Elevate the radar systems,

Which maximize The antenna's range.

The mounts also provide Equipment stability

While traveling over Rough waters.

Boat-radar mounts are one Of the most critical pieces

Of navigation equipment To have on deck.

Radar-mount construction

Begins with A computer-generated drawing

That specifies the height And angle of the tower.

The parts are made from Extruded marine-grade aluminum.

A machinist clamps The first top plate in a jig

And sets the tower upside down On the top plate.

The jig holds The tower in position

As he tack-welds The assembly in place.

After clamping side gussets To the tower,

The technician turns it Right-side up

And inserts the bottom tabs In a baseplate

To position it for assembly.

Using an angle ruler,

He confirms that the tower Stands at 90 degrees.

Then he welds The radar-equipment tower

To the base.

He sets the tower on its side

To measure locations For tack welds,

Marking each with a pen.

Next, he makes larger Stitch welds intermittently.

This will secure the gussets To the tower.

The machinist installs A gusset arm or bracket

In the middle Of the radar tower.

Using a metal puck as a guide,

He centers another top plate On the gusset arm.

He clamps it And measures its placement

To verify that It's properly centered,

And welds it to the arm.

He removes the puck

And installs another Mounting arm at the base.

A computerized drill Cuts bolt holes

In a radar-mounting plate.

Radar-bolting patterns vary, So it configures them

To match up with A specific radar system.

Once the bolt holes are placed,

The drill carves around The border of the plate,

Reshaping it From square to round.

The circular profile Will match the base

Of the satellite-radar system.

In a process known As countersinking,

He bevels the rims Of the bolt holes

To a graduated profile.

This method will provide A stronger connection

Between the mounting platform And the radar system.

With a special deburring tool,

The technician removes

Sharp edges left by The countersinking process.

He smooths the outer edges Of the mounting plate

Using a hand sander.

The mounting plate Is placed in a tub

Of vibrating ceramic stones Mixed with water.

The friction removes Any lingering imperfections

And sharp edges.

Another technician Cuts aluminum wings

For an accessory extension.

The extension could hold A number of accessories,

Including a radio, gps antenna, Or deck lights.

The parts are hollow In order to house wiring.

The wings will be assembled To a center trunk.

But first, they cap one end Of each wing.

This wing will contain wiring

Snaked through from holes In the sides of the trunk.

The technician welds a wing To each side of the trunk.

This step completes the Accessory-extension structure.

Next, it's time to build an arm For a navigation light.

A hydraulic press bends the arm To the desired curvature.

A measuring tool indicates The angle of the bend.

The technician drills a hole for The installation of the light.

After a powder-coat finish has Been applied to all the parts,

The mount is ready For assembly on the boat.

By using critical Navigational equipment,

This boat-radar mount Will ensure

That any boater will be able To find their bearings.

Narrator: european radiators Exude both warmth and style.

The heating-tube technology

Can be modified for electric Or hot-water heating systems

And can be made In a range of designs.

These radiators can Blend into a background

Or stand out to make a statement On the wall.

This european-style radiator Is typically mounted to a wall

So it doesn't Take up floor space,

Allowing more room For furniture and people.

Making panel radiators Starts with steel flat tubes.

Using a circular saw,

The machine cuts A stack of the tubes to length.

These flat tubes Will be held together

By struts known as headers.

An automated drill punches holes For bushings into the ends.

At the next station,

A machine inserts bushings Into the holes

And welds them together.

Another welding device

Seals the ends Of the flat heating tubes.

The tubes are stacked.

Meanwhile, technicians Prepare the headers,

Which are made Of square steel tubes.

An automated machine punches Holes in the headers.

These holes will allow hot water To flow throughout the radiator.

A circular saw cuts the header To its specified length.

Most radiators are custom-made,

And sizes are determined

By the heating requirements Of the space.

The headers are equipped With endcaps and fittings

To supply water and vent air.

A technician inserts the caps Into the ends of the header tube

And hammers them down.

He clamps several Of the capped headers

In a fixture.

The fixture Holds them in position

As an automated welder joins The caps to the headers.

Here is the header tubing

Before and after The holes were punched

And the endcaps were welded.

With the header clamped Into another fixture,

A drill carves a threaded Connector into the side.

This connector will be used To plumb the radiator

To the hot-water system.

It's now time to build The grid of heating tubes.

First, a machine moves The header into position.

An automated arm slides The flat heating tube

Into place on the header,

And a welding device Joins them together.

The automated welder

Installs flat tubes On each side of the headers

And applies the company logo.

Strips of steel will be used

To make fins That direct heat upward.

A machine punches a series Of notches in the steel

To mount the fins to the back Of the radiator.

A hydraulic press bends The notched steel,

Creating An accordion-like profile.

These ridges create pockets

That will capture hot air And allow it to rise.

The fins coil up At the end of the line

For easy transfer To the next station.

At this point, All the flat tubes

Have been fully assembled To the headers.

An operator places the fins,

Which have been cut To a specified length,

On the back Of the flat-tube grid.

A machine welds the fins To the heating tubes

Between the folds.

This step produces A heating panel

That will radiate heat Up and out.

Another team member Installs metal trim

On the top of the radiator.

He places mounts On the back corners

And welds them together.

These mounts will house Threaded bolts,

Which will be used to level The radiator to the wall.

The radiator is now Fully assembled.

The radiator undergoes A quality-control test.

Technicians pump in air And submerge it in water.

If bubbles appear, It indicates a leak.

If not, the radiator is removed From the water.

Electrostatically charged Epoxy particles

Are sprayed onto the device,

Which provide A protective layer.

This european-style radiator Is now ready

To release some major heat.
