Define the map and goal
Represent the environment as an occupancy grid, mark start and goal cells, and decide how obstacles are encoded and updated.
Plan a field path. Balance path length and safety.
Field robot planning finds a collision-free route between start and goal on a map. Practical concerns include map fidelity, vehicle kinematics, dynamic obstacles and latency between planning and actuation.

Field robot planning finds a collision-free route between start and goal on a map. Practical concerns include map fidelity, vehicle kinematics, dynamic obstacles and latency between planning and actuation.
A proposed application is a local planner that produces safe routes between waypoints inside a farm zone, helping an operator supervise autonomous passes. This starter does not include actuators, sensors or deployment integration.
Represent the environment as an occupancy grid, mark start and goal cells, and decide how obstacles are encoded and updated.
Use a graph search such as A* on the grid to build a simple, reproducible route planner that prefers shorter paths.
Measure path length, clearance from obstacles and planned vs actual tracking error in simulated trajectories.
Run the planner in a simulator or replayed sensor traces and add safety checks and human-in-the-loop overrides for deployment.
The supplied starter implements a grid-based A* search: it parses a small static ASCII grid, locates S and G, expands neighbours, computes Manhattan heuristic and returns a shortest discrete grid path. It does not model vehicle kinematics, sensors, dynamic obstacles, ROS interfaces or simulator traces.
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 code runs A* on a tiny hard-coded occupancy grid; it lacks field-specific data, vehicle kinematics or control, sensor input, dynamic-obstacle handling, ROS/simulation integration and any performance evaluation against realistic traces.
Proposed extension: replace the ASCII grid with simulator traces or SLAM-produced occupancy maps, add a kinematic feasibility filter for the robot and run closed-loop tests in a simulator.
This is a potential application pathway, not a delivered product. The supplied starter does not implement this service or validate it with real users.
