This is a teach pendant, and traditionally,

it's how you teach a robot arm to do something.

Two of the problems with programming robots the traditional way

are that you need to tell it exactly what you want it to do,

The other is that the robot assumes that nothing changes.

You just manually drive the tip of the robot

and then hit 'record,' and remember that point,

then you drive it over to the other place and hit 'record,'

and remember that point, and then, when you play,

And it can do that over, and over, and over again.

In the event that there is some error or something moves,

The robot will still go exactly where you told it to go the first time,

and that can result in a crash, or breaking something,

or injuring a person. It's just like any computer.

It will do exactly what you ask it to do,

writing code generally meant using what's called 'assembly language'.

You would have to literally tell the processor

to move things from one memory address to another,

or to change specific pixels on the screen.

you would be telling the chip every single thing that it had to do.

As time moved on, programmers got higher level languages.

the system works out the boring details for you.

If you've ever worked with a spreadsheet, then that counts.

Writing a formula in Excel, that's enough.

In the end, sure, it all gets converted to assembly language.

For most programmers, they never even have to think about it.

The team here at Autodesk's Pier 9 in San Francisco are

Basically, the biggest robot that we have in the lab,

which we call 'Ash,' is essentially a big,

robotic 3D printer that's printing in stainless steel.

We have a MIG welder that is depositing stainless steel onto a metal plate.

By activating the MIG welder while moving the robot, we're building a weld bead,

and then we're building beads on top of each other.

You would typically use welding to stitch two pieces of metal together.

What we're doing is using the same technology,

in order to produce a separate piece of finished material.

The motors in the robot arm are told, “move this way.”

It's just that human's original instructions are a bit more abstract,

and they're filtered through another couple of layers.

Using a teach pendant would be pretty impractical for these complex curves.

They go to an X and a Y, and then up and down.

This robot can point in various directions.

The robot needs to know not only where it is,

but how it should point when it gets there.

and the software figures out the instructions set for the robot

that will result in a print, that is what we want.

One of the things we're developing is a closed loop feedback system,

where the robot is actually aware of what it's doing.

it's keeping track of the quality of the print that it's doing.

It will actually correct, reprogram itself in real time,

What we're working on is a vision system,

where between vision and a couple of other sensors,

we can monitor and supervise the status of the prints.

If the welder runs out of wire, or if something else happens,

the robot would traditionally have no way of knowing.

Not all the robot's movements are being directly controlled by a person.

than just having an error message pop up.

The only reason I'm allowed this close is because

I'm literally holding the emergency stop button in my hand,

Our robot currently has no way of sensing us. What currently happens is

when a person that shouldn't be near a robot gets close to the robot,

It would be great, and we're interested in a future

where the robot can know that person is there,

with vision or some other kinds of sensing,

Self driving cars, hospital heart monitors,

basically everything electronic: ultimately,

The more levels of abstraction between the programmer and the bare metal,

Thank you very much to all the team at Autodesk,
