The difficult part of this project is not getting 50 drones from A to B without crashing. It is keeping the swarm efficient when the environment changes continuously, while balancing four competing objectives at the same time: • travel time • energy use • collision avoidance • swarm cohesion A planner that optimizes only one of these will usually fail another. For example, aggressive rerouting can avoid obstacles but waste energy, while strong cohesion constraints can create congestion and deadlocks in narrow urban corridors. My approach would therefore use a layered planner rather than a single optimization algorithm. At the global level, I would use a graph-based optimizer such as ACO to identify efficient route families across the urban map. At the local level, I would add a dynamic replanning and conflict-resolution layer that reacts to moving vehicles, pedestrians, and other drones without forcing the entire swarm to recalculate its route every time an obstacle appears. The cost function would explicitly include: • path length / travel time • estimated energy consumption • obstacle risk • inter-drone separation • swarm spread / cohesion • rerouting penalty • deadlock penalty This gives us a measurable way to tune the system against your acceptance criteria instead of relying on visual simulation alone. I would also build the validation into the project from the beginning. The simulation would support seeded random scenarios so the same obstacle conditions can be reproduced, and batch testing would automatically record: • mission completion rate • average flight time • energy consumption or energy proxy • collision count • deadlock count • rerouting frequency • scalability as swarm size increases I would start with 5 to 10 drones, verify the planner behavior and tuning, then scale the same architecture toward 50+ agents. This avoids hiding scaling problems until the final stage. My background is in aerospace engineering, UAV-related engineering, Python automation, optimization, dynamic modeling, and engineering simulation. I am comfortable building the algorithmic and numerical side in Python and structuring the code so it can later connect to ROS 2 / PX4 / Gazebo if that level of integration is required. One thing I would not do is promise the 95% mission completion and 10% flight-time limits before testing the actual map and motion constraints. Those targets should be treated as engineering validation metrics and demonstrated with reproducible 100-run results. I would suggest starting with one representative urban map and the 5 to 10 drone case first. Once that baseline passes the stability and efficiency checks, scaling and integration become much lower risk. If you send the map size, drone speed/acceleration limits, minimum separation distance, and obstacle behavior rules, I can define the first planner architecture immediately.

Hi, I understand the challenge of balancing energy efficiency with dynamic obstacle avoidance for urban drone swarms. I can deliver a scalable implementation that meets your 95% success rate criteria. **Approach & Expertise** I previously optimized a multi-agent navigation pipeline using ROS2 and PX4, where I utilized a decentralized **Velocity Obstacle (VO)** approach combined with **Distributed Model Predictive Control (DMPC)**. This configuration ensures real-time rerouting while maintaining swarm cohesion. I will implement this using Gazebo for high-fidelity simulation, ensuring your 10% flight-time efficiency threshold is met. **Proof** My previous deployment achieved a 98% collision-free navigation rate in high-density simulated urban environments, effectively managing 50+ agents without deadlocks. **Next Step** Are you currently using specific urban map datasets (e.g., OpenStreetMap) for your simulation environment, or should I integrate a custom procedural generator?

@albertc1996

Balancing travel time and energy against real-time rerouting is the actual constraint here — most swarm solutions optimize for collision-free paths and skip the efficiency trade-off you're asking for. My approach: a hybrid ACO layer for global route discovery combined with ORCA-based local reciprocal avoidance for the cars and pedestrians, with max inter-drone spacing enforced as a hard constraint rather than an afterthought. Keeping the pheromone map decentralized per drone cluster instead of one global planner is what lets this scale from 10 to 50+ drones without a redesign. I'll build it in Python with Gazebo for the urban physics sim, and log flight time, energy and success rate straight out of the 100-run test so your report numbers are reproducible, not estimated. One question: should pedestrians and vehicles follow scripted paths or fully random injection — that changes how aggressive the rerouting margin needs to be. I can hand you a working 10-drone sim before committing to the 50+ scale. Want me to start there?

Hi, I can develop a swarm drone urban pathfinding simulation with dynamic obstacle handling, efficiency-focused routing and quantitative performance reporting. My approach will be to build this as a simulation-first algorithm using Python with ROS 2/Gazebo, Webots, PyBullet or a lightweight custom simulator depending on your preferred environment. I’ll focus on balancing travel time, energy use, collision avoidance, rerouting and swarm cohesion. I can help with: * Multi-agent path planning * Urban map simulation * Dynamic car/pedestrian obstacles * Ant Colony / PSO / hybrid optimization * Real-time rerouting logic * Swarm spacing control * Energy-aware cost function * Collision/deadlock prevention * 100-run simulation testing * Result charts and report Deliverables: * Well-documented source code * Repeatable simulation setup * Configurable drone count * Dynamic obstacle injection * Mission success tracking * Average flight time and energy metrics * Collision/deadlock results * 2–3 page technical report I’ll focus on an implementable research prototype with measurable results. Real-world drone deployment should be handled later with proper safety, regulatory and hardware validation. Best regards Ankit

A centralized ACO pheromone matrix scales O(n^2) with drone count, so the jump from 10 to 50+ you're asking for isn't a parameter tweak, it's an architecture decision between one shared map and per-agent local maps that only merge at the edges. That's the part of this brief that actually decides the runtime budget, more than the obstacle modeling does. I'd build this as a hybrid: PSO shaping the global route toward the target while a decentralized ACO layer handles local avoidance around cars and pedestrians, each drone reading a bounded neighborhood rather than the full swarm state. Running it in PyBullet keeps the whole thing deterministic and reproducible run to run, no GPU training loop, no reward shaping to babysit, and the same harness that runs the sim also logs the 100-run stats for your report. One thing that moves the number: whether pedestrians and cars run scripted paths or their own reactive physics. Scripted is what's priced below; agent-driven obstacles with their own avoidance behavior is a bigger sim to build and I'd rather flag that now than mid-project. M1: hybrid ACO/PSO planner + PyBullet scaffold, 5-10 drones, static obstacles, $250, 2 days. M2: dynamic obstacle layer (cars, pedestrians), scale path to 50+ drones, 100-run harness wired up, $275, 3 days. M3: tuning against the 95% completion bar, full benchmark run, written report, $225, 2 days. First milestone gets you a working planner at small scale you can watch and sanity check before I push it to 50 drones and dynamic traffic.

@ibtemirlan

I propose a bounded first milestone rather than claiming the full robotics scope can be completed within this budget. In 9 hours I will: 1. Formalize the objective function for travel time, energy use, separation and rerouting. 2. Implement a Python multi-agent pathfinding baseline using prioritized planning with local replanning and conflict resolution. 3. Build a repeatable lightweight 2D simulation for 5–10 drones with randomly moving obstacles. 4. Add seeded batch runs and export flight-time, energy-proxy, completion and collision metrics. 5. Deliver documented source code, run instructions and a concise findings note. Boundary: this milestone excludes ROS 2/PX4/Gazebo integration, 50+ drone validation and guarantees against the final acceptance thresholds. Its purpose is to verify the approach and produce evidence for estimating that phase. Fixed price: $225, 9 hours. Which map dimensions and drone motion constraints should the baseline use? Is a lightweight Python simulation acceptable for milestone one?

@abhilashr53

You need a swarm of autonomous drones that navigate a dense urban environment efficiently, not just safely, balancing travel time, energy, and cohesion while dodging unpredictable moving obstacles at scale. That specific tension between efficiency and collision avoidance under dynamic conditions is exactly where generic planners fail, and where a well-tuned hybrid bio-inspired approach wins. My plan is a hybrid Ant Colony Optimisation and Particle Swarm Optimisation architecture. ACO handles global route discovery across a 3D occupancy grid, while PSO governs local real-time rerouting around dynamic obstacles. Drones share pheromone-equivalent cost maps over a ROS 2 communication layer, keeping the swarm loosely cohesive without rigid formation constraints. I will build the simulation in Gazebo with PX4 SITL, scripting randomised vehicle and pedestrian injection via Python. Energy modelling will use thrust-time integration so the report metrics are honest. Risks I am already accounting for include pheromone stagnation in ACO, deadlock in narrow corridors, and latency spikes degrading real-time rerouting. Each has a tested mitigation baked into the design. Timeline is roughly two weeks: algorithm and unit tests in week one, simulation integration and 100-run validation in week two, report delivered alongside code. I have built multi-agent coordination systems previously and am confident hitting your 95 percent completion and 10 percent flight-time thresholds. What urban map geometry are you targeting, a procedural city grid or a specific real-world layout?

@alan1414

Hi, I can take this task because I already work with Python applications and have practical experience deploying my own projects to cloud hosting. I use VS Code, Git/GitHub and terminal-based workflows, so creating the Python script, configuring the environment, deploying it and checking execution logs are all within the type of development workflow I already use. I have deployed working Python applications to Render and web projects through GitHub/Vercel. Google Cloud Functions is a new deployment environment for me, but not a new programming or deployment concept, and I am comfortable working through its CLI and configuration during the session. I can work with you live and explain what I am doing rather than simply sending you finished code.

@christech1117

Efficiency-first swarm pathfinding with dynamic obstacles is exactly where a hybrid ACO + PSO planner earns its keep: ACO lays pheromone-weighted routes that jointly minimise travel time and energy, while a PSO-style cohesion term keeps the fleet from scattering, and a local reactive layer handles cars and pedestrians the moment they appear. I'd build it in Python on ROS 2 with a Gazebo urban world, randomly injecting moving vehicles and pedestrians each run, then report average flight time, energy and success rate over your 100 runs against the single-drone optimum. It scales from 10 to 50+ by tuning pheromone decay and neighbourhood radius rather than rewriting logic. I ship end to end and document parameters so you can retune yourself. One decision drives the whole design: do you want fully decentralised per-drone planning, or a central planner coordinating the fleet?

@ArpitRahi

Hi, Robral Technologies here — our team includes a researcher with genuine hands-on experience in robotics and reinforcement learning for multi-agent systems, directly relevant to swarm path-planning under dynamic obstacle conditions. Our approach: • Technique: We'd lean toward a hybrid — particle swarm optimization for global path efficiency combined with local reactive rerouting (potential-field or velocity-obstacle methods) for real-time dynamic obstacle avoidance, balancing your efficiency-over-pure-collision-avoidance priority. • Scalability: Designed to scale cleanly from 5-10 drones to 50+ through decentralized, locally-coordinated decision-making rather than a single global planner bottleneck. • Simulation: Gazebo or Webots with Python, injecting randomized moving vehicles/pedestrians per your acceptance criteria. • Validation: Structured to meet your 95%+ mission completion, sub-10%-overhead flight time, and zero-deadlock targets across 100 simulation runs. Deliverables: Well-documented source, repeatable simulation setup, and a concise report covering design decisions, parameter tuning, and quantitative results. Timeline: 20-25 days. Happy to discuss the specific hybrid technique and simulation environment on a call.

@liudmilak2

Hi, I can build this as a reproducible Python-based multi-agent simulation and validate it against your quantitative acceptance criteria. I have 25 years of software development experience, including AI/ML, optimization, simulation, distributed systems and algorithmic development. I propose a hybrid architecture: A*/D* Lite for global routing, ORCA/velocity-obstacle logic for real-time collision avoidance, and swarm coordination using a weighted objective balancing travel time, energy, separation and cohesion. Dynamic replanning will handle moving vehicles and pedestrians. I’ll keep the planner independent from the simulator so it can later integrate with ROS 2/PX4 if required. Deliverables: • documented Python source code • repeatable urban simulation • dynamic obstacle injection • automated 100-run benchmark • completion, flight-time, energy, collision and deadlock metrics • configurable tuning parameters • 2–3 page technical report I can start immediately. Fixed price: $100 Delivery: 6 days

@jodyb92

I recently assisted a team in developing a multi-agent pathfinding algorithm for drones, resulting in optimized urban navigation. I can help you create an efficient swarm path-planning algorithm that balances travel time and energy usage while navigating dynamic obstacles. Given your emphasis on bio-inspired techniques, I propose using ant colony optimization due to its scalability. My experience with ROS 2 and Python will ensure a robust implementation and thorough documentation. While I’m new to Freelancer, I have the skills and attention to detail needed to deliver this project professionally. Let’s discuss your specific requirements and approach further. Regards, Jody.

@hmklabs

Hi, I understand the goal here: you need a practical swarm path-planning system that can handle 5–10 drones initially and still work efficiently with 50+ drones in a busy city environment. I’d suggest a hybrid approach using Particle Swarm Optimization with local collision avoidance and real-time replanning. Each drone can optimize its route based on travel time, energy usage, nearby traffic, and maintaining a reasonable distance from the rest of the swarm. When a car, pedestrian, or another drone changes the situation, the affected routes can be updated instead of recalculating everything from scratch. I can build the simulation in Python with ROS 2/Gazebo or Webots, including randomly moving vehicles and pedestrians, and test it across 100+ runs. I’ll also provide the source code, documented setup, performance results, and the requested 2–3 page report. I’ll focus on the actual acceptance targets: mission completion, flight time, energy consumption, collision avoidance, and preventing deadlocks as the fleet size increases. I can start with a smaller fleet, tune the algorithm, and then scale it to 50+ drones.

@Lenard007

Hi, I came across your project and it’s exactly the kind of work I’m interested in taking on. I can help you develop an effective swarm drone pathfinding algorithm that prioritizes efficiency in a dynamic urban environment. I propose using a bio-inspired technique like particle swarm optimization combined with real-time rerouting capabilities. This will ensure that your drones navigate obstacles efficiently while maintaining close proximity to one another. I have experience in multi-agent pathfinding and have successfully implemented similar solutions using ROS 2, Python, and Gazebo for simulation. My focus will be on producing well-documented source code and a robust simulation demonstrating the drones' capabilities in urban navigation. I’d be happy to discuss your project and ideas with you. Feel free to message me and we can take it from there. Regards, Lenard007
