Industry Brief, August 18, 2026: Bypassed interlocks, free training, AMR charging

By MillBrief Editorial · August 18, 2026 · Retrospective edition, published September 23, 2026

This is a retrospective edition. The brief did not run on August 18, 2026; we wrote it on September 23, 2026 using only reporting that was published on or shortly before August 18, 2026, and it makes no forecasts.

This is a retrospective edition covering August 18, 2026, using only reporting published on or up to two days before that date. Today: a fatal accident inside a robot-served washer cell and the key that switched its guarding off, a state-funded way for Ohio shops to train people on robots at no cost, an integrator’s case that charging is where AMR projects go wrong, and a pharmacy chain growing a mobile-picking fleet it started small. Our own words, links to the original outlet, vendor numbers labelled as vendor numbers.

A bypass key, an energized gantry and a fatal accident at a Stellantis engine plant

The Detroit News (read here in its syndicated copy) reports on three Stellantis worker deaths in the US within two years. The one that concerns automation buyers most happened at the Dundee Engine Plant on April 7, 2025. The plant was being retooled for a new four-cylinder engine, and Ronald Adams, 63, was working alone on a large industrial chamber washer when he was found pinned between a robotic arm (a gantry) and a conveyor. He died after reaching hospital.

According to court records cited by the paper, the washer’s safety mechanism had been “electronically bypassed” with a special cheater key, so the robot and conveyor stayed energized while people worked inside. Lawyers for the washer supplier, Fives Cinetic, argue the accident would not have happened had the safety features not been deliberately defeated. One worker said he had reported the robotic system moving unexpectedly in “dry run” mode two days earlier; a supervisor denied knowing of it. The family’s lawyer says there is no evidence Adams used the key himself. A judge refused Stellantis’s bid to move the widow’s Wayne County lawsuit to the workers’ compensation system, and a Michigan OSHA investigation is ongoing.

The other two deaths were different in kind: a Toledo worker caught on a conveyor that, according to OSHA, lacked adequate guarding (Stellantis settled the fine for about $11,000, down from roughly $16,000), and a fall from a loading bay. A University of Michigan safety researcher quoted in the piece called the run of deaths “not a smoking gun” but a prompt to check that safety policies are actually enforced.

Why it matters: The failure here was not the robot, it was the ability to switch its protection off. Maintenance and changeover, not normal production, are when cells are most dangerous and when bypasses are most tempting. When you buy a cell, ask the integrator how guarding bypass is controlled, who holds any override keys, how maintenance mode limits robot motion, and how lockout is documented. Put that in the questions you ask an integrator and budget for the training behind it; it is one of the hidden costs of automation that should never be cut.

Ohio funds about 3,000 no-cost robotics course places, aimed partly at smaller manufacturers

Robotics Tomorrow carries the announcement: the Association for Advancing Automation (A3) and the Mahoning County Career & Technical Center, with VAZA Consulting, will offer robotics and automation training free to Ohio residents. The money is a $499,000 grant from Ohio’s Individual Microcredential Assistance Program, which is expected to cover around 3,000 course enrollments through June 30, 2027.

Two online A3 courses are open now: an introduction to industrial robots, and a course on the business case (ROI) for automation. Five more are due in the coming months; A3 says its training covers topics such as robot safety and mobile robot safety. The programme is open to students, adult learners, current workers and employers, and the announcement says it places particular emphasis on small and mid-sized manufacturers.

Why it matters: Skills are routinely the constraint after the robot arrives, and paying for them is often what stalls a first project. If you run an Ohio plant, this is a free way to get an operator or maintenance tech through an introduction, and to get whoever signs the purchase order through the ROI course before the quote lands. Pair it with our own payback worksheet. Outside Ohio, it is worth asking your state workforce agency whether a similar microcredential or training grant exists.

An integrator’s warning: model AMR charging on your worst day, not your average one

A contributed article on Robotics Tomorrow, written by the team at HOJ Innovations, a warehouse systems integrator, argues that charging is the most under-modelled part of mobile robot projects. It sets out three approaches: opportunity charging (short top-ups in natural gaps), scheduled charging (longer sessions, which usually means buying extra robots to cover the gap) and battery swapping (fast, but with spare packs, swap stations and labour to run them).

The central warning is about opportunity charging. On a normal day there are enough gaps to keep batteries topped up; on a peak day the gaps disappear, fleet charge drifts down, and robots run short during exactly the surge they were bought for. The authors also say lithium iron phosphate handles frequent partial charging well but costs more and needs thermal management, while lead-acid suffers from partial charging. They advise sizing the fleet for aged batteries that have lost their first 10 to 20 percent of capacity, and planning the electrical work (circuits, panels, possibly transformer capacity, permits and lead times) alongside the robots, with charging staggered to limit peak-demand charges.

Why it matters: This is an integrator’s opinion piece, not a study, but the checks are sound and cheap to ask for. Before you sign, ask the vendor to simulate fleet state of charge across a full peak shift using your real duty cycle and end-of-life battery capacity, and get an electrician’s quote for the charger circuits. Both are classic reasons automation projects slip.

Brightpick grows a pharmacy picking fleet from nine robots to a planned 74

Robotics & Automation News reports that Brightpick will add 44 Autopicker mobile picking robots for Dr. Max Group, a European pharmacy chain, split between a site in Ostrava in the Czech Republic and one in Bratislava in Slovakia, both due in the second half of the year. That would take the group to 74 robots.

The relationship began in late 2023 with nine robots at the Prague warehouse of Viapharma, Dr. Max’s sister logistics company, and grew to 30 there. The companies’ figures for Prague: up to 20,000 items picked a day, a 95 percent cut in manual picking labour, 40 percent more warehouse capacity and picking errors practically eliminated. A Viapharma logistics director says pickers were moved to more skilled work, particularly quality control. These are vendor and customer numbers; no independent measurement is cited.

Why it matters: The pattern is the useful part: a small first deployment, a measured scale-up at the same site, and only then replication elsewhere. That is how a mid-size operation should approach any new automation, and it is the logic behind our guide on what to automate first. If a vendor quotes you headline gains like these, ask for the baseline they were measured against and the ramp time to reach them.
