This algorithm is placed just before the measurement update step: for $k = 0$ to $k < N$: (where N is the number of landmarks seen so far), compute $\psi_k = h_k(\hat{\xi_t^-}) \Sigma_t^- h_k(\hat{\xi_t^-})^T + R $, calculate the predicted measurement $\hat{z_t^k}$, and finally, compute the mahalanobis distance $d_k = (z_i - \hat{z_k}) \psi_k (z_i - \hat{z_k})^T$.

Docker configuration for Turtlebot3 Gazebo Simulation. Beginning with Transforms $T_{1b} = (0, 0, -D)$ and $T_{2b} = (0, 0, D)$ we can extract their Adjoints: Then, we write Twist $V_b$ in each wheel frame where $V_i = A_{ib} V_b$, noting that $v_y = 0$ for a 2D system: Hence, we can extract wheel speeds $\dot{\phi_1}$ and $\dot{\phi_2}$: Using the above two equations, we can construct our motion equation matrix: where \(H = \frac{1}{r} \left[\begin{array}{ccc} -D & 1 & 0 \\ D & 1 & 0 \end{array} \right]\), To get our body Twist $V_b$, we compute the pseudo-inverse of H in $V_b = H^+ u$.

Next, a circle fitting algorithm was used to estimate a centroid and radius for each cluter. Then, after computing the theoretical measurement using $\hat{z_t^i} = h_j(\hat{\xi_t^-})$, get the posterior state update: Note that this algorithm is written such that we perform our full EKF SLAM update once we have received both odometry and measurement data.
