*** The Biggest Rig Ever? ***
MRMC upgrade The VFX Co's Cyclops with a 9m Long Arm

Is this the biggest motion control rig on the planet? Mark Roberts Motion Control were proud to deliver this month an upgrade to the VFX Co's Cyclops motion control system to allow it to carry their 9 metre long Carbon Fibre Arm - almost doubling the original arm length on the Cyclops. The Cyclops is the largest motion control rig available from MRMC. The London based VFX Company came to MRMC to request the ability to switch between using the standard arm which gives 6 metres of lens height and their Carbon Fibre arm which comes in 3 sections allowing it to be up to 9 metres long and giving a lens height of about 10 metres (over 30 feet)!

This made the Cyclops so tall that we could not attach all 3 sections or lift all the way up without hitting the ceiling. The work required a new sub-arm to be made to allow the new and old arms to attach securely to the Cyclops, as the clients wanted to be able to switch between both types of arm for various stages in the shoot. The work also had to fit in with the VFX Co's busy work schedule, so there was limited time for the whole sub-arm to be designed, made and tested.

as any further and the factory ceiling would have been hit!!!

 

*** The New "Modula" Rig System *** 

Having had so many enquiries from clients about a low cost motion control system that can be gradually upgraded and added to, as well as the ability to mix and match different axes of motion such as a head with track or a head with lift, MRMC have designed a system that is modular, lightweight but still highly rigid to give precise motion and the capability of being a complete dolly with Jib arm. The lift and the track can be separated and each run on its own. The lift mechanism in particular uses the concept developed for the Milo of having a thin but broad skin to keep the system lightweight but very rigid. The column is about 30cm in diameter but is very thin and extremely rigid to give very accurate movements, even with heavy side to side accelarations from the track. A jib arm with motorized (and computer controlled) rotate can also be added as an upgrade.

Such a system would not replace a full motion control rig but complements the larger designs like the Talos and the Milo. You would not get the same performance as the full moco systems but would make definite improvements on systems based on ordinary dollies which are then motorized. Because the "Modula" rig is designed for motion control from the start it is more rigid than a dolly that is simply converted. It is designed specifically to run with the Ulti-head.

*** Wireless and Tilt Options for the Ulti-head *** 

New and exciting options are continously being developed for the Ulti-head. At IBC we showed an Ulti-head with the new Pan slip-rings to allow for unlimited rotation.
Now we have the secondary tilt support option which adds more rigidity to the L-shaped Ulti-head by easily turning it into a U-shaped head and also allows for much greater payloads than the standard 35kg. The secondary tilt support easily adjusts to allow for a variety of camera heights and widths as well as different size roll rings or dutch rolls.

Additionally we have also started work on a Wireless option for the Ulti-head when used as a remote head. This will allow it to become a fully remote head with no control cables.

*** CGI Virtual Camera Handwheels - The Motion Box - MOBO*** 

The use of handwheels (or Panbars) combined with a virtual camera in a CGI world has been growing in leaps and bounds. Initially used on purely CG Animation projects like "Polar Express", a number of live-action feature films and projects have since been using the handwheels as a way to allow the cameraman, DoP or director to immerse themselves in the 3D world to get the exact shot they want. The concept is very simple, a CGI scene (for a live-action or animation film) has been created by a 3D artist, but it is down to the cameraman to decide where the "virtual" camera should be in the shot, and what the camera motion should be. So why not give him exactly what he is used to, a set of handwheels that connect to the CG computer and he can control the camera just like he would on a live set. Such a system has been used now on major feature films like The Aviator, Monster House, and Beowulf as well as a number o f still confidential projects.

The MSA-20 handwheels, sometimes referred to as The Motion Box (MOBO) when used in this manner, consists of handwheel electronics made by Mark Roberts Motion Control which have special software to allow them to export the data in realtime to the CG computer. It then shows the cameraman a pre-visualization of his camera move on a monitor, just as he would see on a monitor on set. Camera Control Inc. in LA have successfully supplied this system to their clients with rave reviews.
