Path Planning & SLAM for Real Robots
Example session with this skill installed
I have a differential drive robot with a 2D Lidar and IMU. I need to set up a SLAM stack for a 5000sqm warehouse and a planner that handles dynamic obstacles. Recommend a stack and metrics.
- Read your context and instructions
- Compiled the path planning
I have analyzed your requirements for a differential drive robot in a warehouse environment. Given the 5000sqm scale and sensor suite, a 2D occupancy grid approach is most efficient.
Recommended Navigation & SLAM Stack
| Component | Recommendation | Reasoning |
|---|---|---|
| SLAM Stack | slam_toolbox (Asynchronous) | Better suited for large maps than Gmapping; handles loop closure effectively in long corridors. |
| Global Planner | D* Lite | Efficiently handles re-planning when warehouse layouts change or paths are blocked. |
| Local Planner | TEB Local Planner | Respects differential kinematics while accounting for dynamic obstacle avoidance. |
| Sensor Fusion | robot_localization (EKF) | Fuses wheel odometry, IMU, and Lidar-based scan matching to minimize drift. |
Benchmarking Metrics
To validate this configuration, we will monitor the following KPIs during simulation runs:
SLAM ATE (Absolute Trajectory Error): Measured via evo using ground truth or loop-closure consistency. Target: < 0.15m.
- Planning Latency: p95 response time for global re-planning when a dynamic obstacle blocks the primary route.
- Path Clearance: Minimum distance maintained from obstacles relative to the robot's 0.6m x 0.8m footprint.
Success Rate: Percentage of navigation tasks completed without collision or localization loss across 50 randomized scenarios.
Next steps
- Configure
slam_toolboxin asynchronous mode to prevent processing lag during the initial 5000sqm mapping run. - Calibrate the Lidar-to-IMU extrinsics to ensure the EKF does not diverge during rapid rotations.
- Run a simulation benchmark in a high-density dynamic obstacle scenario to tune the TEB costmap inflation layers.

About this skill
From occupancy grids to loop closure — choose, tune and validate.
Implement and tune robot path planning and SLAM - grid and sampling planners (A*, D* Lite, Hybrid-A*, RRT*, lattice), trajectory optimisation, and 2D/3D SLAM (slam_toolbox, Cartographer, RTAB-Map, ORB-SLAM3, LIO-SAM/FAST-LIO) - with simulation benchmarks and metrics (ATE/RPE, success rate, path quality). Use when the user needs a robot or drone to plan paths, build maps, localize, or when a planner is slow/unsafe or a map drifts.
Includes an EXPERT.md reference (exact parameters, thresholds, failure diagnosis).
Acceptable use: civil and commercial applications only. Any military, paramilitary or weapon-related use is prohibited, as stated in the skill itself.
