New MkII robot gripper from DAGU

Dagu has had an aluminium gripper available for some time now so we decided it was time for a re-design. The new MkII gripper has some significant improvements on the original.

  • Brass sleeves in the joints improve rigidity and eliminate the need for adjustment.
  • A 2:1 gear ratio increases gripping torque while utilizing the full 180° travel of the servo.
  • A spring loaded clutch protects the servo gear train while providing spring tension for gripping objects.

Miniature servo magnetic clutches

Miniature servos are great for robotics, they are small and cheap. Unfortunately they have very small plastic gears that strip easily so they always need replacing....  or do they?  Not any more!!!

Magnetic servo clutches from DAGU

After years of being frusatrated by stripped gears in my servos I have finally done something about it. DAGU is now producing servo clutches to suit 8g and 9g miniature servos.

Unlike normal servo savers, Dagu servo clutches can be continuously rotated without damage to the clutch or the servo. They look like a servo horn but are a few millimeters thicker. They can be configured for both standard and continuous rotation servos. Here are some common configurations:
