Part Features

Idler : The idler is firmly assembled with Dynamixel by hooking mechanism and additional frames such as hinge can be assembled on it.


Idler Cap : The cap protects debris such as screws getting into the Dynamixel through the hollow structure.


Keep the cables organized to make sure no cables are trapped when assembling the hollow structure.

The tangled cables can and will cause communication error.
