Holding Downforce45 N (EDF Vortex)
Payload Capacity1.5 kg (NDE Probes)
Control Dual-TierROS 2 / FreeRTOS
Motor PWM Frequency20 kHz
SYSTEM ARCHITECTURE & ACTIVE ADHESION
Engineered an industrial wall-climbing inspection robot utilizing an active aerodynamic vortex 70mm Electric Ducted Fan (EDF) generating 45 N holding force combined with passive N52 magnetic track locking. Implemented a dual-tier control hierarchy: ROS 2 Jazzy on Raspberry Pi 4 for high-level mission logic and ToF telemetry, paired via UART to an ESP32 FreeRTOS controller for deterministic motor actuation and 50Hz tilt stabilization.
CORE DESIGN HIGHLIGHTS:
- Designed in Autodesk Fusion with 3mm CNC carbon fiber plates, Pololu 30T rubber tracks, and 4x 164 RPM planetary gear motors.
- Delivers 1.5 kg payload capacity for Non-Destructive Evaluation (NDE) ultrasound probes and HD thermal inspection.
- Dual-tier control: ROS 2 Jazzy mission supervisor (RPi4) coupled with FreeRTOS 20 kHz deterministic motor PWM (ESP32).
- Qualified for NeX-Gen Robotics Challenge 2026 (IDREA | Round 1 Concept Presentation).
