Abstract:
Hard disk drives have evolved rapidly with computer miniaturization
into highly compact and integrated electromechanical systems. Hard
drives contain many precision mechanical parts which may prove useful
in the design of small precision robots. The advantages of parts taken
from hard disks include low cost, miniaturization, high quality, and
for some applications, cleanliness. We report the results of
engineering tests on flat coil head positioning actuators taken from
hard drives of sizes ranging from a 5.25" to 1.8" media diameter. We
also perform a simple analysis which suggests that requirements for
torque per unit mass are lower for small robot arms. The results
suggest ways that hard disk actuators can be utilized in mini robotic
designs and points the way towards improved versions of these designs
for robotic purposes.
