eMotimo Spectrum ST4/Dana Dolly Integration Motion Control Kit

eMotimo has released a kit that integrates their motion control system with a Dana Dolly. It looks like a nice option for those who already have a Dana Dolly.

4-Axis Control

The eMotimo Spectrum ST4 provides control over 4-axis and is capable of supporting up to 15lbs. A motor integrates onto the Dana Dolly to provide movement on the slide axis, which is belt driven. The pan & tilt control is provided directly from the motion control unit. Using the eMotimo Fz motor will allow the system to also control the focus point.

The integration kit includes two belt clamps and 12 feet of timing belt. The clamps attach to the two ends of the Dana Dolly and a motor is connected to the main ST4 unit.

Setting and controlling the unit is done by the included wireless PS4 controller.


The Spectrum ST4 has a number of programs which you can use to easily set up the unit including parallax loops & push/pull moves, the example below combines a parallax move with an additional focus pull.
