Cinebot / Robot as Car Rig - Moving Vehicle and G-Force Safety

NEEDS_REVIEW SAFETY CRITICAL

Summary

The chat includes questions about mounting Cinebot/robot systems on moving cars and whether g-forces could trigger safety stops. Partial replies mention low-loader/truck approaches and long cable routing, but no complete safety-approved workflow was extracted.

The evidence supports a conservative conclusion only: treat moving-vehicle robot use as a specialist grip/stunt/engineering rigging problem, not a normal robot setup. A Mitchell mount or cobot label does not by itself make the robot safe for road or process-vehicle use.

Symptoms

  • A production wants to mount a Cinebot Mini or Max on a moving vehicle and you need to know whether g-forces during acceleration or braking can trigger the robot's safety stop.
  • The robot is being considered for a car-roof or process-trailer rig and you need to assess what engineering or rigging review is required.
  • A camera battery or accessory came loose from the rig during a vehicle move.
  • The UR controller is located in the car boot and you need to route cables from the boot to an arm on the roof.
  • You are planning a moving-vehicle robot shoot and need a safety checklist before the shoot day.

ISSUE-ENV-003

First Reported

2024-12-22 - Markus asked whether Cinebot could be used with its Mitchell as a car rig and whether g-force could trigger safety stops.

Additional Reports

  • 2025-05-31 - Cinebot Mini on car: long cable from UR controller in boot to arm on roof.
  • 2026-05-06 - moving-road car rig question; replies mentioned low-loader trailer and 3-phase generator truck setups.

Key Risks

  • Safety stop triggered by vehicle acceleration, braking, vibration, or bumps
  • Rigging loads exceeding vehicle/roof/Mitchell mount capacity
  • Controller/base separation and cable strain
  • Power supply and emergency stop access while moving
  • Legal road-use and stunt/safety requirements
  • Arm dropping or shifting during transport/bumps if not restrained
  • Quick-release plates, batteries, lenses, monitors, and accessories detaching under acceleration
  • Cable pulls between controller, base, arm, vehicle, and generator

Current Community Evidence

[NEEDS_REVIEW] 2024-12-22 - User: Markus

Asked whether Cinebot could be used with its Mitchell as a car rig, and whether g-force could trigger the cobot safety stop. No definitive safety answer was extracted.

[LIKELY] 2025-05-31 - User: Timothy Heys Cerchio

For Cinebot Mini, one approach needs a long cable from the UR controller inside the base, located in the car boot, to the arm rigged to the roof. This is a routing note, not full safety approval.

[EXPERIMENTAL] 2026-05-06 - Users: Steve Schweiger, Buddy Bleckley

Possible production approaches included placing the car and robot on a low-loader trailer, or using a truck with a built-in three-phase generator. This needs formal rigging/safety review.

[LIKELY] Lock down every accessory under g-force

2021-11-28 - Steve

One vehicle/g-force discussion noted that everything needs to be locked down securely and that quick connectors should not be trusted under g-forces; a V-mount battery reportedly came off under load. This was not Cinebot-specific, but it is directly relevant to moving-vehicle robot rigs.

[LIKELY] Secure robot arm for road bumps during transport

2025-09-13 - Marcin Biegunajtys

A transport note reported that a Bolt arm can drop if the vehicle hits a bump, so the roll axis/arm should be supported and restrained in a safe store position during travel. This is transport guidance, not approval to operate while moving.

Interim Safety Guidance

Do not treat the Mitchell as the whole safety case

The robot/camera payload, vehicle mount, road surface, acceleration/braking, cable routing, power, E-stop access, and controller location all need to be engineered together. A car-roof Mitchell plate alone does not answer the moving-load problem.

Prefer process trailer / low-loader style setups

Where the shot requires the car to appear moving, the safer production pattern is usually a low-loader/process trailer or vehicle platform engineered by grips/stunts, with the robot and power distribution mounted to a rated structure rather than directly to a normal vehicle roof.

Minimum checks before any moving-vehicle test

  1. Get a qualified key grip / vehicle rigger / stunt safety review.
  2. Confirm the rated load path for robot, base, arm, payload, and accessories.
  3. Restrain all camera accessories, batteries, monitors, cables, and lens motors against acceleration and bumps.
  4. Provide a hardwired E-stop position accessible to the responsible operator/safety person.
  5. Strain-relieve controller, power, and robot cables across any vehicle/body gap.
  6. Test static first, then crawl-speed, then production speed only after sign-off.

Do not publish as an approved car-rig workflow

The chat does not contain enough evidence to approve Cinebot/Bolt operation on a moving vehicle. This page is a risk checklist and escalation pointer until MRMC/rigging/stunt engineering confirms an operating procedure.

WhatsApp Excerpts

  • 2024-12-22 04:52 - Ben Myers: Cinebot Mini IK Rig.blend
  • 2024-12-22 06:56 - ~ Markus: That’s a nice Christmas present right there, thanks 🙏
  • 2024-12-22 06:59 - ~ Markus: So you haven’t done any animations within blender that you exported to the robot successfully? Or did I get that wrong..?
  • 2024-12-22 08:11 - ~ Markus: On to something different.. How about using the cinebot and its Mitchel for a car rig, like on a modulus x? As it is a co-bot, could there be any issues with g-force triggering the safety stop?
  • 2024-12-22 08:27 - Ben Myers: I have but it's not that straight forward just yet. Working with MRMC to streamline that process.
