Define map and task
Represent the inspection area as an occupancy grid or mesh and decide start, goal and waypoints for coverage or point inspections.
Plan obstacle-avoiding paths. Weigh path cost and distance.
Autonomous inspection drones need reliable path planning, obstacle handling, and evaluation under realistic sensor and dynamics constraints. A useful baseline is a reproducible planner on a map representation, but production systems add perception, low-level control, latency checks and safety monitors.

Autonomous inspection drones need reliable path planning, obstacle handling, and evaluation under realistic sensor and dynamics constraints. A useful baseline is a reproducible planner on a map representation, but production systems add perception, low-level control, latency checks and safety monitors.
A proposed application: plan safe inspection routes over a mapped structure (roof, pipeline, bridge) and replay them in simulation for human verification. This build is a prototype suggestion and not ready for live inspection use without further safety work.
Represent the inspection area as an occupancy grid or mesh and decide start, goal and waypoints for coverage or point inspections.
Build a deterministic planner (for example A* on an occupancy grid) so you can measure path length, clearance and collision-avoidance properties in static maps.
Replay planned paths in a physics simulator (PyBullet or Gazebo) and check tracking error, control latency and collisions under noise.
Replace the static grid with simulated sensor inputs and a localisation module, then measure failure modes and recovery strategies.
The supplied starter implements a simple grid-based A* planner: it locates S and G in a small ASCII occupancy grid, uses Manhattan distance as a heuristic, expands neighbours, records came_from and cost_so_far, then reconstructs and prints the planned path and its length.
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 minimal A* on a tiny, static 4x5 ASCII grid. It has no dynamics, vehicle model, sensor inputs, obstacle uncertainty, collision checking beyond grid cells, ROS integration, simulator traces or control/trajectory following — so it does not implement an autonomous inspection system end-to-end.
A proposed extension: connect the planner to simulator traces and a simple controller so planned paths are executed in PyBullet or Gazebo, add sensor-based occupancy updates and a supervisor that vetoes unsafe motions.
This is a potential application pathway, not a delivered product. The supplied starter does not implement this service or validate it with real users.
