Machine, Assemble, Repair: How We Build Atlas | Boston Dynamics
A Boston Dynamics Prototype Operations team member explains how the company builds and improves Atlas, from precision machining through assembly and testing, alongside its engineers.
Chris Thorn, Atlas hardware team lead at Boston Dynamics, discusses the new Atlas design with industrial designers Aaron Abroff and James Kucera at Boston Dynamics.
Abroff says Spot’s design started with making an unfamiliar robot work as a product, with protective cladding and room for customer equipment. Stretch was shaped for warehouses, while Atlas is designed for manufacturing tasks that call for humanlike capabilities without copying human proportions.
Kucera describes design priorities including round-the-clock uptime, broad joint movement, durability, and quick repairs. Atlas uses two batteries so it can replace one while continuing to operate. Shared actuators and interchangeable limbs simplify production, maintenance, and future redesigns.
The team chose passive cooling to avoid fans on the actuators, shaping visible fins to move air behind the robot’s padding. Safety clearances influenced the robot’s height and width, while offset arms and legs help reduce pinch risks and preserve movement. Camera placement and range of motion also shape the body so Atlas can see its surroundings and reach work areas.
The product head replaces the prototype’s rounder look with light rings that can support interaction without giving Atlas a literal face. Neck movement helps the cameras see the feet and reach overhead areas. Kucera says the head must combine desktop-level computing with waterproofing and the ability to withstand falls.
Thorn notes that robots fall frequently during lab development, so the head must be robust without becoming too heavy, costly, or complicated. The team is weighing repair time against durability requirements. Modular construction and staged hardware updates let behavior development proceed while subsystems continue to improve.
