A camera, LiDAR sensor, force-control feature or humanlike shape is not proof that a robot is safe to approach. The relevant question is whether the complete system can detect hazards and respond reliably under the conditions in which workers will use it.
What does “collaborative” mean for a humanoid robot?
“Collaborative” is about a robot system and the way it is operated—not a guarantee attached to a robot’s shape or product category. A system may use monitored stops, speed and separation monitoring, or power and force limiting (PFL), depending on its risk assessment and intended task. A demonstration of a robot sharing space with a person does not show that the same setup is safe in a different workplace.

In the United States, OSHA says there are currently no specific OSHA standards for the robotics industry. Its robotics standards page lists consensus standards and guidance, including ISO 10218 and ISO/TS 15066, but OSHA says those consensus standards are not OSHA regulations. Employers still need to meet applicable workplace safety duties; the technical standards and the particular installation help inform how risks are addressed.

ISO/TS 15066:2016 sets safety requirements for collaborative industrial robot systems and their work environment, supplementing ISO 10218-1 and ISO 10218-2. ISO says the specification was reviewed and confirmed in 2022 and remains current. Its stated scope is industrial robot systems described in ISO 10218; its principles may be useful elsewhere, but that does not establish that every humanoid or service robot is covered. ISO 10218-1:2025 addresses industrial robot safety requirements, with integration and applications covered by ISO 10218-2:2025. Do not infer that a humanoid is “ISO certified” without evidence for the exact model, configuration, use and relevant conformity assessment.

What can a robot’s sensors actually tell you?
Sensors can support safety functions, but the component list alone says little about whether people are protected. A safety-related system has to detect a relevant condition, process it through appropriate control logic and trigger a dependable response—such as slowing or stopping the robot. Its performance depends on detection coverage, response time, stopping behavior, installation and foreseeable failures.
| Sensor or function | Potential role | What must still be established |
|---|---|---|
| Camera or depth camera | Can provide visual or depth information about people and objects. | Whether the sensor and its control path are suitable for a safety function, cover the relevant area and respond reliably in the actual conditions. |
| LiDAR or other worker-detection sensor | Can contribute to detecting a person and maintaining separation from a moving robot. | Coverage, response time, stopping distance and how the safety system behaves if detection is impaired or fails. |
| Collision or contact sensor | Can detect contact or a collision condition in the configuration where it is installed. | Which contacts it detects, how quickly it acts and whether the resulting response is adequate for the task and contact conditions. |
| Safety-related controls and monitored functions | Can use sensor inputs to initiate a monitored stop, protective stop, speed limit or separation response. | Documentation and validation for the complete integrated function—not simply the presence of a sensor. |
Manufacturer specifications illustrate the difference between listed hardware and demonstrated safety performance. Unitree’s G1 page lists a depth camera and 3D LiDAR. Its G1-D page lists LiDAR, depth cameras, physical collision sensors and low-obstacle detection sensors for the chassis configuration described there. Those feature lists do not establish safety-rated performance or suitability for a particular shared workspace. Unitree also advises users to keep sufficient distance and use the robot carefully.
Is there a safe force limit for a humanoid robot?
There is no single force number that makes every robot collision harmless. PFL is a collaborative operating technique, not a universal guarantee. OSHA’s Technical Manual says force, power and ergonomic parameters for force-limited systems are determined by risk assessment; both transient contacts and quasi-static contacts—where a body part can be pressed or trapped—need consideration.

The risk can change with the robot, end effector, contact geometry, body location, speed and nearby structures. A quoted contact limit is meaningful only when it is tied to the applicable authoritative standard, the relevant body region and contact condition, and testing of the application. A number detached from those conditions should not be treated as a promise that a collision will be injury-free.
One possible layered approach is to combine PFL with speed and separation monitoring. The robot can move faster while people remain farther away, then slow as they approach so that any possible contact stays within the limits assessed for that application. This is an example of combining safety functions, not blanket approval for close contact.

The right safeguards depend on the risk assessment, including whether contact is expected and what hazards the task creates. A deployment may require several layers rather than reliance on any one sensor or robot feature.
- Control access and exposure: use barriers, restricted zones or interlocked access where the risk assessment calls for them.
- Detect people and manage motion: integrate suitable safety-related detection with validated protective stops, safe speed limits or speed and separation monitoring as appropriate.
- Assess contact risks: where contact is part of the intended operation, evaluate PFL and the end effector for the actual task and contact conditions.
- Plan abnormal conditions: define what workers should do if detection is obstructed, the robot behaves unexpectedly, equipment is damaged or a person needs to enter a restricted area.
- Manage maintenance and recovery: establish safe maintenance and lockout practices, emergency procedures, supervision and worker training.
- Use PPE where appropriate: select it as part of the assessed safety approach, not as a substitute for suitable engineering safeguards.
Warning lights and sounds can alert workers, but OSHA’s guidance does not treat warnings alone as adequate safeguards. The system’s safety functions and the procedures supporting them need to match the hazards.

Ask for evidence tied to the actual robot, end effector, task and workplace layout—not just the model name or a general product brochure. The review should address how the system performs in its intended operating conditions and what happens when conditions change.
- The risk assessment for the task and workspace, including foreseeable interactions and hazards.
- The exact robot and end-effector configuration covered by the assessment.
- Documentation of safety functions, their limits and the controls that use sensor information.
- Measured stopping response and detection coverage for the installed layout.
- Validation records for force- or pressure-limited use, where relevant to the application.
- The design for guarding, restricted access and worker entry into the robot’s area.
- Maintenance, abnormal-condition, emergency and recovery procedures, plus worker training requirements.
NIOSH’s Center for Occupational Robotics Research focuses on worker safety for people who use, wear or work near robots. Its work is relevant background, but general robotics research cannot replace assessment of a particular installation.
What do current humanoid safety assessments establish?
A 27 May 2026 announcement from Fraunhofer IPA describes an assessment program for humanoid robots that includes functional-safety assessment and collision-force measurement using a force sensor. The announcement identifies a Unitree G1 EDU-4 with Dex3-1 hands and firmware 1.04 as the technical basis for the work. This is a specific testing example, not an injury-rate estimate and not evidence that all humanoid robots have passed the same assessment.
The sources cited here do not establish a broadly representative humanoid-worker injury rate or a general safety comparison across humanoid models. Product demonstrations and a list of sensors cannot fill that gap or show that a particular workplace is safe.
