Robowerk offers a small
selection of servos that are built for R/C model purposes. By adding
the Missing Axle, these servos are also usable in robotics.
When choosing a servo you should keep its use inside the robot in mind.
A plastic gear servo is quieter and has little wear, but metal gears
are far superior in strength.

Die Missing Axle - shop
This kit adds a free spinning second axle to the back of any Robowerk
servo (other servos possible). The additional axle significantly
reduces loads on the main axle that are typical for robots. Mounting
the Missing Axles requires disassembly of the servo, drilling, and
hot-glueing.
Axle and rivets are dimensioned for mounting material between 1 and 2
mm.
We recommend our 6.9mm drill bit for a perfect fit of the bearing.

 6.9mm drill bit - shop
This drill bit is required to drill the correct size hole for the
Missing Axle in the bottom plate of the servo. To avoid slippage of the
bearing, you should not use a 7mm drill. |
