Quanser test -3 DOF Helicopter
The 3 DOF Helicopter is a compact laboratory platform that emulates the motion of a rigid-body helicopter around three axes: pitch, travel, and elevation. The helicopter body is attached to an arm via an instrumented joint that lets it pitch freely. The arm’s other end connects to a base with a two-degree-of-freedom joint, allowing vertical motion and rotation about the vertical axis. Dual propellers, powered by DC motors, generate thrust to control movement. High-resolution encoders monitor every axis for precise feedback. A slip ring mechanism on the vertical axis prevents cable wrap during continuous rotation. This setup is ideal for developing and studying control laws in flight dynamics.
