History of Industrial Robots: 1954 to 2026

When the First Industrial Robot Was Invented

The first industrial robot dates to a 1954 U.S. patent application filed by American inventor George C. Devol Jr. for a "Programmed Article Transfer," granted in 1961 as U.S. Patent 2,988,237. Devol partnered with engineer Joseph F. Engelberger, and the two founded Unimation, Inc. to build the machine.

The first working industrial robot, the Unimate, was installed on a die-casting line at the General Motors Inland Fisher Guide plant in Ewing Township, New Jersey in 1961. It unloaded hot metal parts from a die-casting machine, work considered dangerous for human operators. The National Inventors Hall of Fame inducted Engelberger in 2011 and credits him and Devol with founding the industry.

The Foundational Timeline: 1954 to 1996

The first four decades of industrial robotics were dominated by hydraulics giving way to electric drives, teach-pendant programming, and a handful of arm geometries that still define the market today. The milestones below trace the mechanical and control breakthroughs that made every later cell possible.

Key Figures Behind the First Generation

A small group of engineers created the templates the entire industry still uses. Devol supplied the programmable-transfer idea, Engelberger productized and sold it, and Victor Scheinman designed the arm architectures that Stanford, MIT, and later Unimation and Adept turned into commercial products. His biography is documented by the University of Minnesota College of Science and Engineering.

On the collaborative side, Northwestern professors J. Edward Colgate and Michael Peshkin filed the original cobot patent in the mid-1990s while working with General Motors, described in the 1997 ASME cobot paper. Their definition of a passive device that guides a human operator was later broadened by industry into today's power- and force-limited arms.

The Japan Robot Association helped shape the SCARA and articulated-arm ecosystem in parallel; the International Federation of Robotics, founded in 1987, remains the primary source for global installation counts.

• George C. Devol Jr. — patented the programmable transfer machine (1954, granted 1961).
• Joseph F. Engelberger — co-founded Unimation and sold the first industrial robot to GM.
• Victor Scheinman — designed the Stanford Arm (1969) and the PUMA (1978).
• Hiroshi Makino — invented the SCARA at Yamanashi University (1981).
• J. Edward Colgate and Michael Peshkin — filed the first cobot patent (1996).

The Cobot Era: 2005 to 2015

The 2000s shifted the center of gravity from large caged arms to smaller, safer, cheaper robots that could work near people. Universal Robots, founded in Odense, Denmark in 2005 by Esben Ostergaard, Kasper Stoy, and Kristian Kassow, shipped its first UR5 in December 2008 — widely credited as the first commercially successful collaborative industrial robot.

In 2012, Rethink Robotics launched Baxter, a two-armed research and light-industrial cobot priced at about $22,000, developed by iRobot co-founder Rodney Brooks. Rethink followed with the single-arm Sawyer in 2015 before shutting down in 2018, but Baxter proved that a compliant, screen-faced robot could be deployed without traditional guarding.

The safety framework caught up in 2016 with ISO/TS 15066, the technical specification that defines power- and force-limits for collaborative operation. It supplements ISO 10218-1:2025, which covers robot safety requirements more broadly. Buyers evaluating cobots should read the cobot guide alongside this history.

Scale, AI in the Loop, and the 2020s

The IFR World Robotics 2024 report counts 541,302 new industrial robot installations in 2023 and a global operational stock of 4,281,585 units — a figure that has roughly doubled in seven years. China alone accounted for 51 percent of new installations.

The 2020s also brought machine learning into the control loop. NVIDIA released Isaac, a simulation and AI platform used to train robot policies in synthetic environments before deployment. Vendors such as Covariant and Osaro commercialized vision-and-grasping foundation models for pick-and-place work that classical programming struggled with.

General-purpose humanoids — Figure, Apptronik, Boston Dynamics Atlas, and Tesla Optimus — began factory pilots in 2024 and 2025. The IFR humanoid brief notes that unit economics and safety certification, not raw capability, remain the gating items for deployment at scale.

How Today's Buyer Should Read the History

The lesson of six decades of industrial robotics is that hardware got cheaper, controllers got smaller, and safety got codified — but the projects that succeed are still the ones with a documented process before the robot arrives. That was true when Unimate landed at GM in 1961 and it is true when a cobot arm lands on a bench in 2026.

The other durable lesson is that categories persist. The SCARA arm from 1981, the articulated 6-axis arm from the Stanford lineage, and the delta parallel arm from the late 1980s still describe most of what a plant can buy today. AI vision and force sensing have made them more capable, not obsolete.

• Match the arm geometry to the motion, not to the vendor's marketing.
• Confirm the safety standard (ISO 10218, ISO/TS 15066) that applies to your cell.
• Compare a modern cobot quote against a used caged arm plus fixturing.
• Ask any vendor for the year their controller architecture was designed.
• Treat AI-in-the-loop features as valuable but auditable, not magic.
