BME 366
Six-DOF Kinematics The Flock
of Birds
Laboratory #1
Objective
To measure 3-D kinematics of the human arm movement using the Flock-of-Birds
magnetic system and to analyze the movement in 6 DOFs.
Features:
RMS errors are 0.1" for translations and 0.5º for rotations
Equipment: Flock-of-Birds
Description: The Flock of Birds system (FOB) consists of a transmitter,
receiver, and bus. The transmitter consists of three orthogonal coils
which generate a magnetic field in a certain sequence. The receiver
contains triaxial minicoils to detect the generated magnetic field.
Due to the magnetic measurement mechanism, there
cannot be magnetic conductive materials nearby. The FOB system allows
up to 30 receivers at once. The FOB uses multiprocessors to reduce computation
time and a Fast Bird Bus (FBB) to transmit data to the host computer.
The system costs less then $3000 and is an economical yet fairly accurate
way to measure 3-D kinematics.
