They are non optimal because there is control noise, and there is also measurement noise.

They tend not to work well if you have no noise in your measurement model or no noise in your controls.

If there is 0 measurement noise, then this function will end up dividing by 0.

So, let's put in a clause that specifies what we believe the actual measurement noise is.

The error is mapped into a matrix s, which is obtained by projecting the system uncertainty into the measurement space using the measurement function projection the matrix R, the characters of measurement noise.

I want you to define the measurement uncertainty matrix, which now is a 2 x 2 that has 0.1 as the main diagonal as measurement noise.

You'll find that there's little corners over here that are either the result of control noise or of measurement noise or of my somewhat deficient implementation.

I now just initialized these positions remain numbers but also assume a certain amount of noise that goes with each particle, 0.05 for the translational noise, 0.05 for the rotational noise, and 5.0 for the measurement noise in those ranges.

Initialize distribution, execute a motion first, then measurement, motion, measurement, motion, measurement, motion, measurement, and so on.

Obviously, there some measurement noise that would be just more or less an added Gaussian with 0 mean.

There is no way to explain these measurements with a fixed velocity, so there has to be measurement noise.

Measurement Update So question 1 is measurement update.

It switches off the noise model, so you will need the noise model for forward simulation of the robot, but you don't need it for computing the probability of the measurement.

I'll call the first measurement X1, the second measurement X2.

There's one last change we have to do to make this code run. We have to actually assume that there is measurement noise.

This is 3D measurement.

What was that noise? What noise? Keep moving.

I copy all the narrowing parameters length, bearing noise, steering noise, and distance noise.

I just add Gaussian noise with the corresponding steering noise and distance noise parameters.

There's also a measurement update step where we use the measurement z.

First, select a truly random number called the seed, this number can come from the measurement of noise, or the current time in milliseconds.

I print the measurement values.

So the measurement is black.

After my first measurement update,

Less noise, please.
