How are units of noise measurement related to units of a sensor's data measurement?
I'm trying to understand how noise is represented for accelerometers, gyroscopes, and magnetometers so that I can match the requirements of my project with the standard specs of these sensors.
I ...

Kalman Filter and the state noise vector?
I'm reading Probabilistic Robotics by Thrun. In the Kalman filter section, they state that
$$
x_{t} =A_{t}x_{t-1} + B_{t}u_{t} + \epsilon_{t}
$$
where $\epsilon_{t}$ is the state noise vector. And ...

Velocity Model Motion in Matlab (Probabilistic Robotics)
I want to implement the velocity motion model in Matlab. According to Probabilistic Robotics page 124, the model is as following
\begin{align*}
\hat{v} &= v + sample(\alpha_{1} v^{2} + \...

Wheel odometry simulation using ground truth
I'm tracking the state of a robot $X=(x,y,\theta)$ where $x$ and $y$ are the ground coordinates and $\theta$ the heading angle.
I have the ground truth states $X_{gt}=(x_{gt},y_{gt},\theta_{gt})$.
I ...
