What Is Boston Dynamics? A Robotics Company Through Examples of Atlas, Spot and Stretch

Boston Dynamics is a robotics company that develops and uses Atlas, Spot and Stretch. Its work includes testing reinforcement-learning control on Atlas, public safety applications for Spot and unloading operations with Stretch. This newspaper’s articles organize the robots’ uses and distinguish research, demonstrations and product announcements.

Why it matters

Viewing Boston Dynamics only as a “humanoid robot company” can obscure Spot’s public safety applications and Stretch’s use in unloading. Separating Atlas’s control research, accounts of work in factories and product announcements by stage makes it easier to assess what the company is testing and which applications it is pursuing.

Explainer

Boston Dynamics is a company that works on robots including Atlas, Spot and Stretch. This newspaper’s articles cover distinct efforts: control research for humanoid robots, public safety applications for quadruped robots and the development of robots for logistics. It is important to look at each robot’s use and demonstration stage, rather than judging the company by its robot names alone. ## What do Boston Dynamics robots do? Atlas appears in this newspaper’s articles as a humanoid robot, Spot as a quadruped robot and Stretch as an autonomous mobile robot that unloads cargo from trailers. The company’s work is not limited to one type of robot. It ranges from control testing for research to descriptions of applications in the field and announcements of robots for logistics operations. ## Atlas tests control using wheels Boston Dynamics built a research test bed by replacing Atlas’s feet with wheels and tested a reinforcement-learning-trained controller on the real robot. The wheeled configuration is for research, not a product; it is designed to run actuators continuously at high torque and speed. A test of reinforcement-learning control on a wheeled Atlas reported that the company evaluated motor characteristics and adjusted its models to narrow the gap between simulation and the real robot. The company has also applied insights gained from the wheeled configuration to the standard Atlas. A separate article also described an example of Atlas performing actual work in a factory. These are different accounts of control research and factory work; they do not show that the wheeled research robot itself was deployed in a factory. Reading this alongside an article about Atlas performing work in a factory helps distinguish research from use in the field. ## Spot for public safety, Stretch for unloading Boston Dynamics has described public safety applications for Spot, including bomb disposal, search, responses to barricade incidents and structural inspections after fires. The company has also outlined standard kits, sensors and remote-control capabilities. Spot’s public safety applications show how the robot can be used to assess hazardous sites and reduce the burden of sending people directly into them. However, the applications described in the article are the company’s own account and do not guarantee performance in every setting. Stretch is an autonomous mobile robot designed to unload trailers. Boston Dynamics’ “Stretch Gen 2” was reported as a robot focused on improved reliability and simplified maintenance. The announcement of Stretch Gen 2 describes the launch of a next-generation robot for unloading in logistics operations. The information in the article does not confirm the scale of deployment or its operating record. ## What to consider when following Boston Dynamics When reading about the company, it is important not to conflate “research testing,” “descriptions of applications” and “robot announcements.” Atlas’s wheeled configuration is a test bed for control technology, while the Spot article covers public safety use cases. Stretch Gen 2 was announced as a next-generation robot for unloading. Each represents a different stage: technology development, examples of use in the field and product development. For readers looking up Boston Dynamics, considering Spot and Stretch as well as Atlas shows that the company’s robots are not limited to humanoid research. At the same time, publicly available information does not confirm deployment numbers, prices or the extent of broad commercial rollout for individual robots. When reading this newspaper’s articles, it is also necessary to distinguish announced plans from information confirmed in actual operations. ## Related articles from this newspaper - Boston Dynamics tests reinforcement-learning control on a wheeled Atlas (2026-11-09) - Forbes publishes an article on manufacturing humanoid robots with wheels (2026-11-09) - Bloomberg reports Toyota Motor has established a dedicated robotics division (2026-11-05) - Boston Dynamics announces “Stretch Gen 2” (2026-11-03) - Samsung tests humanoid robots designed to operate 24 hours a day; possible unveiling at CES 2027 (2026-10-20) - The Robot Report covers humanoid robots working in factories (2026-10-17)
