Kessler Multi-Axis Motion-control Time-lapse Tutorial – sandbox/Uli Formula

Create complex multi-axis time-lapse motion control using Kessler Crane‘s Oracle Controllers

I made this tutorial to share a formula I designed (with the help of my plasma physicist buddy Ulrich Buddemeier) to help create complex multi-axis time-lapse, vfx, and other shots with less time in the field and greater accuracy.
While the joystick on the controllers works great, I was searching for another option for many complex moves and decided to leverage the accuracy of the nodal points on the Revolution Head to help me work more intuitively.
This tutorial was made using the 2.08 Oracle firmware. The new 3.0 firmware offers a bridge mode (among other useful new features) which should allow one to use two Oracle controllers to accomplish the same shots that previously needed 3 using the sandbox/Uli formula.

Please share your thoughts and results. I will add more info as it becomes available, including stereoscopic 3D experiments using this formula.
Here is a list of  gear used, either seen in this tutorial or otherwise used:

Kessler Cineslider – 3′
Kessler Revolution Head
Kessler Oracle Controller x 3
Kessler ElektraDrive motors

Anton/Bauer Dionic 90
Anton/Bauer Satellite Plate
Anton/Bauer Multi-tap
Anton/Bauer Extensions
The Hot Rod Camera P-Tap Power Adapter Cable (AB2CB) for Anton/Bauer D-tap to Canon LP-E6 Battery
Manfrotto Carbon Fiber Tripod
Pclix Intervalometer
Zeiss 100mm Lens
ViewFactor Contineo Powered Cage
Canon 5D Mark II

(in progress)

 

I’ll be adding more info to flesh out the text explanation and step by step, but until then…

Why this solution?

This formula is for designing complex multi-axis shots with accuracy and speed in the field – for when you want to be able to move cam to start and end points and quickly “set” that move without having to negotiate recording moves that may be complicated to get right, or too time-consuming on set.

Basic Concept -

FOR MULTIAXIS MOVES BASED ON FULL ROTATION
WITH SET TIME AS FRACTION OF ROTATION. Uses 3 Controllers.

We can do with by using the nodal points for each axis in conjunction with a formula that I designed with help from Ulrich, my plasma physicist buddy.

FOR MULTIAXIS MOVES BASED ON FULL ROTATION
WITH SET TIME AS FRACTION OF ROTATION. Uses 3 Controllers.
PROGRAMMED MOVE: 360° IN 24Hours

Determine desired shot.
Note nodal point on Revolution Head for Pan and Tilt.
TAKE READOUT DIFFERENCE BETWEEN START/END POINT (IE D=70)
Decide how long the shot should take
DESIRED TIME (IE T=5H)
Use Formula below to calculate Pan and Tilt
TMOVE=T/F = 360*T/D
IE 360*5/70 = 25.7H

or using minutes
TMOVE=T/F = 360*T/D (1440 MIN)
IE 360*5/70 = 25.7H
