Robo Arm
A robotic camera arm runs a programmed path with inhuman precision, repeatable every take for product geometry or a stunt match. No operator shake; the spline is the performance.
Narrative function
The path must be identical every take. Commercials, previs stages, a bottle that must match a CGI pass, a stunt that must fit a plate: the arm does not interpret.
A human dolly will drift. An orbit-360 can be walked and will breathe.
Bolt cam is a throw, not a repeatable spline (unless the throw is itself robotic). If you want error and life, do not use the arm.
How it works
Motion-control arm or a six-axis robot, programmed XYZ and pan/tilt/roll. Speed can be inhumanly even or inhumanly fast.
Product tables, crash pads, or a repeatable orbit. Prompt: Robotic arm move around [Subject], programmed path, inhuman precision, product or stunt geometry.
When to use it
Use it when takes must match: VFX, product, a stunt plate. Do not use it for a scene that needs human drift.
Compared with similar shots
360-Degree Orbit can be a human walk or a circular dolly with breath. Bolt Cam is a crash throw aimed at impact.
Robo-arm is the repeatable spline, any shape, no shake.
In film
Commercials and previs stages are the native grammar: bottles, cars, and stunt geometry that must composite. The precision is the style.
Prompt it
Programmed, repeatable, no shake. Still: Robotic arm move around [Subject], programmed path, inhuman precision, product or stunt geometry.
Video: A precise robotic-arm path around [Subject], repeatable, no human shake. Name the path shape.
Forbid handheld error.
What usually goes wrong
The usual wrong cousin is a steadicam orbit. The tell: a little sway, a human accel.
The fix: write programmed path, identical takes, no operator shake.
Questions
What is Robo Arm in film?
A robo arm is a robotic camera on a programmed path, repeatable every take, with no human shake. Product and stunt geometry live here.
Robo Arm vs 360-Degree Orbit
An orbit-360 is a circular walk or dolly and can breathe. A robo arm can orbit, but the point is a programmed spline that matches take to take.
When should I use Robo Arm?
Use it when the path must be identical: VFX plates, product, stunts. Do not use it when you want human error.
How do I prompt Robo Arm for AI image or video?
Write a programmed path with no shake. Example: Robotic arm move around [Subject], programmed path, inhuman precision, product or stunt geometry.
Melies can generate this Robo Arm
Melies is the AI filmmaking workspace. This Robo Arm opens with the camera path and prompt already loaded, so you generate the move instead of describing it from scratch.
