The FR08-D101K Hinge Frame Set allows you mount 2 MX-106 DYNAMIXELS side-to-side. The MX-106 robot actuators can be 'linked' together in a fashion that allows them to move together as one, double torque, actuator when in this configuration. You will need a FR08-H110K Adapter Frame Set to connect the 2 MX-106T horns.
See the Double MX-106T Robot Joint Kit for an all-in-one joint kit.
