A comprehensive deep-dive into ArduPilot’s MAVLink 2.0 protocol stack — covering code architecture (33 files, 8 vehicle types), message routing (20-entry table), bucket scheduling (10 streams), parameter protocol, mission protocol, MAVLink FTP, serial control, high-latency mode, signing/security, 40+ commands, and 80+ message types.

A step-by-step guide to compiling and flashing PX4 firmware for FMU-v6C (STM32H7) flight controllers — covering environment setup, source code management, default/raptor/neural board configurations, four flashing methods, first power-on calibration, and 6 common troubleshooting FAQs.

A detailed engineering guide to designing the flight control system for a small reusable rocket — covering thrust vector control allocation, small-disturbance linearization for pitch/yaw/roll channels, controller design with stability margin analysis, and 100-run Monte Carlo shooting validation under normally distributed parameter errors.

A University of Macau team transforms a quadrotor into a low-cost, indoor rocket thrust-vector control testbed using a gimbal-mounted carbon fiber cylinder. Published in IEEE Transactions on Aerospace and Electronic Systems, the system achieves centimeter-level trajectory tracking with adaptive backstepping control.

A systematic analysis of the rumored Russian Volna Kupol Garant (VKG) Starlink jamming system. Cross-examining Ukrainian and Russian sources, evaluating technical claims about 8-channel uplink interference, and assessing reliability against Starlink’s known anti-jamming capabilities.

Complete hands-on tutorial for setting up ArduPilot Follow Me mode. Track a moving vehicle from the air using an open-source flight controller, Mission Planner, USB GPS, and telemetry — step by step with all parameters, wiring, and safety tips.

Carnegie Mellon University researchers demonstrate agile quadrotor interception using only 3D direction vectors — no distance measurements needed. Trained with differentiable quadrotor dynamics and APG, the system achieves ~30% improvement over point-mass baselines at speeds up to 10 m/s.

A step-by-step Mission Planner guide for complete beginners. Learn waypoint planning, survey grids, NAV/CONDITION/DO commands, auto-photo missions, and more. No prior experience needed — just open Mission Planner and follow along.

Six most common APM/PX4 customer build issues from a field engineer’s perspective: compass interference, vibration, current sensor accuracy, GPS fix problems, takeoff flips, and link loss. With troubleshooting checklists and hardware design solutions.

RobotMCP connects LLMs to ROS robots through MCP protocol: auto-discover interfaces, control via natural language, sim-to-real shared interfaces. Technical deep dive with working demos and honest boundary assessment.
