What kind of figure this source publishes
The BLS category is a relative rank, not an absolute level, and it is not a first-hand measurement: it groups an occupation's percentile ranks across several published studies into four bands. It is not an employment or wage forecast, not a probability of adoption, and it does not separate automation from augmentation.
Task-level exposure

Values in this tab are predicted labels, not observations. Eloundou et al. (2023) published two rating regimes — human raters and GPT-4 — and the β shown here is derived from the GPT-4 rater basis alone; the same task can take a different value under the other regime. The unit and the meaning differ from the observed shares (%) in the other tabs, so do not place them on the same axis.

0.79/ 3· Robot exposure index
Scale, basis and source
Each physical task is graded 0–3 by the setting in which robots that have been deployed, sold or demonstrated could do it (0 none · 1 purpose-built robot settings such as a fenced machine cell or a bottling line · 2 structured facilities such as a hospital pharmacy or a container port · 3 unstructured settings such as a private home or a construction site), and the grades are averaged by share of working time
Physical tasks among this occupation's O*NET 29.3 tasks
Anthropic estimated the grades and time shares with Claude Opus 5 using web search, as of 2026.
The robot exposure index is a different measure from the AI exposure figures on this site and cannot be added to or compared with them. It does not measure actual adoption or cost, and 0 also covers occupations with no physical tasks.

ILO occupational description
AI Changing Work links the ISCO-08 unit groups below to this occupation by applying the U.S. Bureau of Labor Statistics crosswalks (2018 SOC to 2010 SOC, 2010 SOC to ISCO-08) as published, without case-by-case selection; each link may be whole or partial.
- ISCO-08 3119Physical and Engineering Science Technicians Not Elsewhere Classified
The definition, tasks and examples below are the ILO's description of that unit group, not of this occupation.
This unit group covers physical and engineering science technicians not classified elsewhere in Minor Group 311: Physical and Engineering Science Technicians. For instance, the unit group includes those who assist scientists and engineers engaged in developing procedures or conducting research on safety, biomedical, environmental or industrial and production engineering.
Tasks
- In such cases tasks would include -
- (a) collecting data and providing technical assistance regarding: efficient, safe and economic utilization of personnel, material and equipment; methods of work and sequence of operations and supervision of their implementation; and efficient layout of plant or establishment;
- (b) aiding in the identification of potential hazards and introducing safety procedures and devices;
- (c) modifying and testing equipment and devices used in the prevention, control, and remediation of environmental pollution, site remediation and land reclamation;
- (d) assisting in the development of environmental pollution remediation devices under the direction of an engineer;
- (e) assisting engineers in testing and designing robotics equipment.
Example occupations
Engineering technician (production) · Fire investigator · Forensic science technician · Quantity surveying technician · Robotics technician · Time and motion study technician

ESCO occupational vocabulary
Each entry below is matched to this occupation in the published ESCO-O*NET Crosswalk (version 1, 2022). The match types are that crosswalk's; the wording is AI Changing Work's.
- radiation protection technicianESCO 3111.12Same scope
Radiation protection technicians monitor radiation levels in buildings and facilities to ensure compliance with health and safety standards, and to prevent dangerous elevations in the radiation level. They take measures to minimise radiation emissions, and to prevent further contamination in the event of radiation pollution, by developing radiation protection plans, in particular for nuclear plants and facilities.
- nuclear technicianESCO 3111.10Overlapping, not the same
Nuclear technicians function as aids to physicists and engineers in nuclear laboratories and power plants. They monitor the procedures to ensure safety and quality control, and maintain equipment. They also handle and control radioactive equipment and measure radiation levels to ensure safety.
