Term
In Graph SLAM, when the x_0 is 0, how do we assign Omega and Xi
matrices?
Give this one a try later!
we assume the Omega matrix for we assume the Omega matrix for
[x0, x0] = 0 and Xi for X0 = 1 [x0, x0] = 2 and Xi for X0 = 0
, we assume the Omega matrix we assume the Omega matrix
for [x0, x0] = 1 and Xi for X0 = 0 for [x0, x0] = 1 and Xi for X0 = 1

How do cars calculate the heuristic function in the real world?
Give this one a try later!
You can calculate in 2D
and use the 2D planning You can calculate in 3D and use
result as a heuristic for the the 3D planning result directly.

You can ignore 2D planning and You can use random values for the
focus on 3D only. heuristic in 3D planning.

What does P stand for in PID controller?
Give this one a try later!
Integral. We steer in proportion to Adaptive. We steer based on
the accumulated error over dynamic adjustments to the
time. error.
Proportional. We steer in
proportion to the Crosstrack Derivative. We steer in proportion
error to the rate of change of the error.

In Histogram Filter,, how is the Move/motion function calculated?
Give this one a try later!
Using convolution (addition).
(using total probability). The Using division (scaling). (using joint
operation of a weighted sum probability)
is called a convolution.
