A Robot Injuring a Worker During Autonomous Operation: Which Economic and Non-Economic Damages Could Be Available?

A worker hurt by a robot running on its own program can usually recover two kinds of money: economic damages — medical care, lost wages, future earning capacity, prosthetics and home modifications — and non-economic damages, meaning pain, suffering, disfigurement, and a spouse's loss of consortium. The split matters because workers' compensation pays only the first kind, and only partially; the second kind comes from a lawsuit against someone other than the employer, typically the robot manufacturer, the systems integrator, or a maintenance contractor.

These injuries are not exotic. A NIOSH analysis of federal fatal-injury data counted 41 robot-related worker deaths in the United States between 1992 and 2017, 78% of them caused by a robot striking the worker and 83% involving stationary industrial robots — the arms bolted inside a fenced cell, not mobile machines. Many happened during maintenance, when a worker was inside the cell and the machine was still live.

Why workers' compensation is the floor, not the answer

Workers' compensation is a no-fault system: you get benefits without proving anyone was careless, and in exchange you generally cannot sue your employer. California's Division of Workers' Compensation describes the standard package — temporary disability at two-thirds of lost gross wages up to a weekly statutory maximum, medical treatment, and a permanent disability rating from 1% to 100%. Other states differ in the numbers, but the architecture is the same. Two gaps follow from that design.

The wage benefit replaces roughly two-thirds of wages and stops at a cap, so a higher earner absorbs the difference. And there is no category for pain and suffering at all — a hand lost in a robot cell produces a percentage rating, not a figure for what the loss actually costs a person's life. Closing those gaps requires a third-party claim: a lawsuit against a company that is not your employer. That is the only route to non-economic damages in most robotics cases.

Which economic damages a robot injury generates

The dominant injuries in this space are severe and permanent. A 2024 study in *Applied Ergonomics* reviewing OSHA Severe Injury Reports found 77 robot-related accidents between 2015 and 2022; the 54 stationary-robot incidents produced 66 injuries that were mainly finger amputations and head or torso fractures, while 23 mobile-robot incidents produced leg and foot fractures. Amputation is the case that shows how far past the medical bill economic damages run.

The MPL Association, citing a Johns Hopkins Center for Injury Research and Policy estimate, puts the lifetime cost of a traumatic amputation at about $509,272, with prosthetic limbs running $5,000 to $50,000 and needing replacement every three to five years. A 35-year-old with a 45-year replacement horizon is looking at a recurring cost, not a one-time purchase. Economic damages in a robotics case typically include:.

Past and future medical treatment, surgery, and rehabilitation
Prosthetics, replacement cycles, maintenance, and fitting
Lost wages to date and reduced future earning capacity
Vocational retraining if the worker cannot return to the same trade
Home and vehicle modifications, and paid attendant care

What non-economic damages cover, and who can claim them

Non-economic damages compensate the consequences that have no invoice: physical pain, mental anguish, permanent disfigurement, and the loss of activities the worker can no longer do. In a crush or amputation case these are frequently the largest single component of a verdict, because the medical bills stop and the disability does not.

A spouse can usually bring a separate claim for loss of consortium — the loss of companionship, household contribution, and intimacy caused by the injury. Where the worker dies, the claim converts into a wrongful death action brought by the estate or statutory beneficiaries, which carries its own non-economic elements for the survivors. These are the damages that workers' compensation structurally cannot reach, which is why the identity of the third-party defendant drives the value of the whole case.

Suing the robot's maker, the integrator, or the maintainer

An autonomous machine has a chain of companies behind it, and the employer's immunity does not extend to any of them. The clearest example is *Holbrook v. Prodomax Automation Ltd.* in the Western District of Michigan, where the estate of maintenance technician Wanda Holbrook — crushed on July 7, 2015, when a robot entered the cell she was working in at a Ventra Ionia plant — sued the systems integrator along with robot makers FANUC, Nachi and Lincoln Electric. The case settled confidentially mid-trial in 2021.

The theories that typically carry these claims are product defect (a design or manufacturing flaw in the robot or its safety controller), negligent integration (how the cell, fencing, interlocks and light curtains were specified and installed), failure to warn, and negligent service by an outside maintenance firm. Which one fits depends on evidence that lives in the machine: controller logs, the safety-PLC program, the lockout/tagout records, and the cell's as-built drawings. The current design benchmark is ISO 10218-1:2025 and ISO 10218-2:2025, which took effect on April 1, 2025, replaced the 2011 editions, absorbed the collaborative-robot content of ISO/TS 15066, and introduced Class 1 and Class 2 robot categories. Note the mismatch that plaintiffs' experts often point to: OSHA's own robotics directive, STD 01-12-002, dates from 1987.

An OSHA citation is evidence, not a payout

If OSHA investigates and issues a citation, the penalty is payable to the government, not to the injured worker. The OSH Act says so directly: 29 U.S.C. § 653(b)(4) provides that the Act neither supersedes workers' compensation law nor "enlarge[s] or diminish[es] or affect[s] in any other manner" the common-law or statutory rights of employers and employees.

The 2025 maximums are $16,550 for a serious violation and $165,514 for a willful one — and none of it reaches the person who was hurt. What the citation is worth is the file behind it. The inspection generates witness statements, photographs, machine specifications, and findings about guarding and lockout practices, gathered while the cell is still in its post-incident state. That record is often the best available description of the scene by the time a third-party case is filed.

Two things that shrink the final number

The first is a statutory cap on non-economic damages, which about half the states apply in some form. Tennessee Code § 29-39-102, for instance, caps all non-economic damages per plaintiff — loss of consortium included — at $750,000, rising to $1,000,000 only for catastrophic loss, defined as paraplegia or quadriplegia, amputation of two hands or two feet, or major third-degree burns. A single-hand amputation, the archetypal robot-cell injury, stays at $750,000 no matter what a jury awards. The second is the comp lien.

California Labor Code §§ 3852 and 3856 let the employer or its insurance carrier recover the benefits it already paid out of the worker's third-party judgment, after litigation expenses and attorney fees are deducted first. In practical terms, the compensation benefits are repaid from the tort award — so the gross verdict and what the worker keeps are different figures, and lien negotiation is a real part of case value. Before either issue matters, preserve the evidence. Ask in writing that the employer and the equipment owner keep the robot cell, its controller, and its safety-system logs unaltered, since a cell is usually cleaned, reprogrammed and back in production within days.

Frequently Asked Questions

Are injuries from mobile robots treated differently from robot-arm injuries?

The legal analysis is the same, but the injury pattern differs. The *Applied Ergonomics* review of OSHA Severe Injury Reports found 23 mobile-robot incidents producing 27 injuries, mainly leg and foot fractures, against 66 injuries from stationary robots that skewed toward finger amputations and head or torso fractures. Mobile cases tend to focus on navigation software, sensor coverage and floor-marking rather than cell guarding and interlocks.

Does it matter that the robot was running unattended rather than being operated by hand?

It usually helps the claim. When no one was steering the machine, the conduct under scrutiny is the design of the safety system and the way the cell was integrated — decisions made by the manufacturer and integrator, who have no workers' compensation immunity. The NIOSH fatality analysis found many deaths occurred during maintenance, where the question is why the machine could move at all with a person inside.

If a similar case settled confidentially, can it still help mine?

Only indirectly. *Holbrook v. Prodomax Automation* settled mid-trial in 2021 with terms undisclosed, so it sets no dollar benchmark. What it does establish is the viable defendant list — integrator plus multiple robot manufacturers — and that such a case can survive to trial against all of them.
