Define task and metrics
Specify whether the goal is mapping, localisation or both and select metrics such as localisation error, map accuracy (IoU) and path success rate.
Simulate SLAM-based mapping. Assess planned paths.
SLAM (Simultaneous Localisation and Mapping) simulation combines sensor models, motion models and mapping algorithms so a robot can localise itself while building a map. A realistic simulation provides sensor traces (RGB, depth, lidar), control inputs, and a map ground-truth; common failure modes include sensor noise, dynamic obstacles, missed loop closures and localisation drift.

SLAM (Simultaneous Localisation and Mapping) simulation combines sensor models, motion models and mapping algorithms so a robot can localise itself while building a map. A realistic simulation provides sensor traces (RGB, depth, lidar), control inputs, and a map ground-truth; common failure modes include sensor noise, dynamic obstacles, missed loop closures and localisation drift.
A proposed use-case is developing and validating indoor navigation strategies for service robots in warehouses or offices; the supplied starter does not implement SLAM or sensor simulation and so cannot validate such applications directly. Any deployment would require rigorous safety testing and a human in the loop for navigation decisions.
Specify whether the goal is mapping, localisation or both and select metrics such as localisation error, map accuracy (IoU) and path success rate.
Collect or generate sensor and odometry traces (lidar/depth, IMU, control inputs) using a simulator like PyBullet or Gazebo.
Integrate a mapping/localisation algorithm (e.g. EKF, particle filter or graph-SLAM) that consumes simulated sensors and produces pose and map estimates.
Compare estimated poses and maps to ground truth, inspect loop-closure failures, and test under different noise and dynamic-obstacle scenarios.
The supplied starter implements a grid-based A* style path-planning demo: it defines a small obstacle grid, finds start and goal cells, runs a priority-queue search using Manhattan heuristic, reconstructs the grid path and prints the planned path and its length. It does not simulate sensors, produce sensor traces, build maps, or run any SLAM algorithm.
while frontier:
_, current = heapq.heappop(frontier)
if current == goal:
break
for nxt in neighbors(current):
new_cost = cost_so_far[current] + 1
if nxt not in cost_so_far or new_cost < cost_so_far[nxt]:
cost_so_far[nxt] = new_cost
priority = new_cost + heuristic(nxt, goal)
heapq.heappush(frontier, (priority, nxt))The starter is a deterministic grid path planner on a tiny hard-coded map. It contains no sensor models, no odometry or landmark processing, no mapping module and no SLAM optimiser; therefore it cannot be used to evaluate localisation drift, loop closure, map consistency or other SLAM-specific properties.
Proposed extension: replace the hard-coded grid with simulated sensor traces from PyBullet or Gazebo, implement a particle-filter or graph-based SLAM pipeline, and log pose and map estimates for quantitative evaluation against ground truth.
This is a potential application pathway, not a delivered product. The supplied starter does not implement this service or validate it with real users.
