They had cleared the obstacle from the road.

That is precisely what we do today.

left, up again, and down again.

What about the obstacle course?

Here is an even more challenging example where our robot Junior approaches a complete road blockage, but its target location is behind the road blockage.

I am starting up over here. These are my obstacles.

No frakking way, Lee.

I had a PhD student work on very narrow openings with smoothing where we used the distance between obstacles as one way to scale the pressure that obstacles would assert on the path to pull away from themselves.

Basically, you can imagine that you set the speed so that you can always come to a safe stop.

Block... block, block.

KT OK, OK, OK. Oh, my God!

So what? We've been on the move.

The lasers scan the environment to detect obstacles a car approaching from the front, the back and also any obstacles that run into the roads, any obstacles around the vehicle.

simulated obstacle course for automobiles

Here is an example of where this occurs.

Here's our familiar grid again.

So you can see it do its job until it finally breaks free and is able to navigate around this blockage onto a different street, as shown over here.

Centennial Highway victims.

One is to use dynamic programming with a stochastic action function. You've learned this in the previous homework assignment.

And we also use three laser range finders.

Watch it go over this.

Obstacle courses, simulated missions.

What you'll see, in fact, is that it's using that half circle leg as a distributed foot.

It's the same as the grid over here.

The second node to expand was this one over here 1, 2, 3, 4, 5, 6, 7.

Now I didn't cheat. I didn't tell it that there's a straight path over here.

Ten fucking seconds. It should take you no less than 10 fucking seconds to negotiate this obstacle.

I wouldn't call it hate mail but letters of really strong concern

As dry leaves that before the wild hurricane fly,

Get the fuck off of my obstacle.

His loss of memory is a psychological problem rather than a physical one.

A Fred Johnson?

Everything is a Remix Part Four

Plug it in with NSA.

Well, erectile dysfunction

Some sort of obstruction in the tunnel.

What's gonna stop me, huh?

My fault, Alan.

Deal unbreaker.

As you can see the maze is changing as the car moves.

This map was made for military reasons.

What is the point?

This is state property!

The road.

It also tells the robot where these obstacles are.
