PX4 / Gazebo Developer – Running Track Pacing Simulation (Software Only)

## Project Overview We are two track-and-field coaches seeking an experienced PX4/Gazebo developer to create a computer-based simulation of a programmable athletic pacing system. Our objective is to simulate a virtual drone following a standard 400-meter running-track oval at controlled speeds and selectable lap times. This initial engagement is exclusively for software development and simulation. We are taking a phased approach, beginning with a basic working simulation before adding more advanced functionality. ## Phase 1 – Initial Project ($300–$400 Budget) For our first milestone, we are looking for a developer who can: 1. Set up a PX4 Software-in-the-Loop (SITL) simulation using Gazebo or a comparable environment. 2. Create a virtual flight path representing a standard 400-meter running-track oval, including straightaways and curves. 3. Program a simulated drone to complete the oval along a continuous, repeatable path. 4. Demonstrate the working simulation and provide the source code, configuration files, and basic setup instructions. The goal of Phase 1 is simply to establish a functioning simulation that we can build upon. ## Potential Future Milestones Following successful completion of Phase 1, we would like to explore: - Programmable lap times (e.g., completing 400 meters in 59 seconds). - Consistent speed control throughout the oval. - Timing accuracy and path repeatability over multiple laps. - A simple interface for adjusting target lap times. - Performance reporting and simulation testing. These additional milestones would be discussed and budgeted separately. ## Preferred Experience - PX4 Autopilot - Gazebo simulation - MAVSDK / MAVLink - Python and/or C++ - Trajectory planning and speed control - Robotics or autonomous navigation simulation ## Project Scope This engagement involves computer-based software simulation only. No physical drone operation, hardware manufacturing, flight testing, or laser equipment is included. ## Budget and Working Arrangement Our initial budget is $300–$400 for Phase 1. We are open to an hourly arrangement, provided the estimated hours and total cost are agreed upon before development begins. We are interested in establishing a longer-term working relationship with the right developer as the project progresses. ## To Apply Please provide: 1. A brief description of your experience with PX4, Gazebo, or comparable simulation environments. 2. Examples of similar simulation or autonomous navigation projects you've completed. 3. Your estimated hours and cost to complete Phase 1. 4. Your anticipated timeline for delivering the initial working simulation. We value clear communication, practical engineering solutions, and a collaborative approach to development.
