Greetings from the Contingent, The journey to gold continues. As we advance in our preparation for Inter IIT Tech Meet 14.0, we now take on the second Low-Prep Challenge in the Autonomous Systems and Controls domain, presented by Drona Aviation. The Low-Prep Problem Statement titled Control System for Drone Stabilization and Precision Motion has been released. This challenge focuses on building a high-reliability, autonomous indoor nano-drone stabilization pipeline capable of centimeter-level precision without GPS or external tracking — relying solely on onboard sensors and real-time control firmware. Short Summary of the Problem Statement: Participants are required to design and implement a complete on-board control architecture that enables a nano-drone to take off, establish a stable hover, lock its position and altitude autonomously, and execute precise 10-20 cm micro-movements in any direction based on user command. The system must fuse Optical Flow, Time-of-Flight, and IMU measurements to achieve drift-free, production-grade stability in indoor environments, while running entirely on the provided MagisV2 firmware and compute constraints. Key Functional Goals: • Stable autonomous hover with minimal drift • Hands-free position lock after takeoff • Precision micro-movements (10-20 cm) on pilot stick input • Smooth acceleration/deceleration with no overshoot • Robust recovery from external disturbances • Clean transitions between hover and movement modes • Real-time sensor fusion from Optical Flow, ToF, IMU and Baro sources • Altitude stability up to 2 meters • High-frequency velocity estimation from optical-flow + altitude scaling • Cascaded Position–Velocity–Attitude control architecture Deliverables: • Firmware on MagisV2 implementing stabilization + micro-movement control • Sensor fusion logic and velocity + position estimation • User-triggered displacement execution with controlled settling • Demonstration video showing stable hover, 10-20 cm movements, recovery handling • Documentation (system design, control strategy, fusion approach, results, tuning) • Parameter reasoning and fallback handling • Consistent performance across multiple flights and varied surface conditions • Full code, configurations, and build/run instructions Problem Statement: https://drive.google.com/file/d/1U1rTjcIOXG_0jSdZIcy3DxE0wXvsvfsy/view?usp=sharing Deadline to apply: 11:59 PM, 29th November (strict and non-extendable) Submission Form (fill with LDAP): https://forms.gle/QRAVNWBX5n7Pjdrp7 Let us push forward with engineering excellence in flight control, embedded firmware, and real-world robotics — and continue leading IIT Bombay toward gold.
