Little Black Duck - 12g, 2Kg/cm miniature servos from DAGU
Have you ever built a robot and then found your miniature servos were not quite strong enough?
Get yourself a flock of ducks! DAGU's little black ducks!
DAGU are now selling a 2Kg/cm servo that is only slightly taller than a standard miniature servo. The height difference allows for thicker, stronger gears and a bearing to support the load.
I have tested this servo by lifting 2Kg of water in a bottle with the string mounted 1cm from the centre of the horn. I used a regulated 6V power supply. This is a true 2Kg/cm servo. The gears are plastic but they are stronger than a standard 1.5Kg miniature servo and the bearing on the output shaft ensures low friction under load.
