PROJECT TOPICResearch Frontiers & Advanced Kinematics
Dual-Rotor Bicopter Aerial Rig
An advanced flight kinematics research concept investigating underactuated aerial dynamics, gyroscopic precession compensation, and high-speed servo thrust vectoring using only two main lift rotors.
Underactuated Thrust-Vectored Flight Control
- ✓Cuts rotor count in half compared to quadcopters, maximizing propeller diameter and aerodynamic efficiency.
- ✓Controls pitch, roll, and yaw purely through high-speed servo tilt angles and differential propeller throttle.
- ✓Demonstrates non-linear control techniques for underactuated dynamic systems.
The Engineering Challenge
Problem / Objective
Quadcopter drones require four separate motors and propellers, increasing aerodynamic drag, electrical wiring, and vehicle footprint.
