Define the task and constraints
Specify input maps, obstacle types, vehicle kinematics, and a success metric such as mean tracking error or collision-free completion rate.
Plan waypoint paths. Respect obstacles and cost.
Waypoint navigation decomposes autonomous flight into a discrete plan of intermediate targets (waypoints) and a low-level controller that follows them. Important practical concerns include obstacle avoidance, dynamic constraints, localisation error, and latency between planning and control.

Waypoint navigation decomposes autonomous flight into a discrete plan of intermediate targets (waypoints) and a low-level controller that follows them. Important practical concerns include obstacle avoidance, dynamic constraints, localisation error, and latency between planning and control.
A proposed application: provide an inspection-route planner that suggests safe waypoint sequences for a human operator to review before execution. For safety, a human should remain in the loop and the planner must not be used for unsupervised flight without further verification.
Specify input maps, obstacle types, vehicle kinematics, and a success metric such as mean tracking error or collision-free completion rate.
Start with a discrete A* or Dijkstra grid planner on map snapshots to produce waypoint candidates for a controller to follow.
Run planned waypoints through a dynamics simulator (or simple kinematic follower) and measure path-tracking error and collisions.
Add realistic sensor noise, latency, and a monitoring layer to trigger safe behaviours or human intervention.
The supplied starter implements a grid-based A* planner on a tiny hard-coded map. It locates start and goal cells, expands neighbours, computes Manhattan heuristic+cost, reconstructs the path and prints it. It does not implement a controller, dynamics, sensors, ROS integration or any continuous-time tracking.
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))
came_from[nxt] = currentThis code is a discrete A* planner on a 4x5 toy grid with hand-coded obstacles. It omits vehicle dynamics, time, velocity/acceleration constraints, sensor models, uncertainty, and controller logic needed to execute waypoints on a real drone.
Proposed extension: replace the toy grid with simulator traces or occupancy maps, generate time-parameterised waypoints respecting kinematic limits, and expose a review interface for an operator to accept or modify routes before execution.
This is a potential application pathway, not a delivered product. The supplied starter does not implement this service or validate it with real users.
